New features, improvements, and fixes shipped to Viktor.

October 10, 2026

Ten new integrations: Buffer, Circleback, Postscript and more

Ten more tools now have one-click cards in the integrations catalog, so you no longer need to wire them up by hand as a custom connection.

  • Marketing and social tools — Buffer (connect with an API key), Vista Social, Postscript and Helium 10 are now in the integrations catalog. Connect them once and ask Viktor to schedule posts, pull campaign stats or check product research.
  • Meetings, feedback and ops — Circleback, Senja, Chaser (Slack Tasks), Motion (Creative Analytics) and Skio join the catalog as one-click connections, so Viktor can read your meeting notes, testimonials, task reminders, creative performance and subscription analytics.
  • SEO data — Senuto's official MCP is now available as a catalog card for search visibility and keyword questions.
October 8, 2026

Grok 4.7 and Nano Banana 2.1 are now available

Grok 4.7 is selectable in every workspace, and Nano Banana 2.1 joins the image generation models at half the price of Nano Banana 2.

  • Grok 4.7 for everyone — xAI's Grok 4.7 is now in the model picker for every workspace, no longer limited to early-access teams. Pick it per chat like any other model.
  • Nano Banana 2.1 image model — Google's Nano Banana 2.1 is now an option for image generation. Ask Viktor to use it by name; it costs about half as much per image as Nano Banana 2.
October 3, 2026

@ mentions for teammates and admin access controls in chat

The web chat composer can now mention Slack teammates with @, and admins can manage who can use Viktor by asking in chat.

  • Mention teammates with @ — Typing @ in the web chat composer searches your Slack workspace members. Pick one and Viktor knows exactly which person you mean, so there is no more guessing between two "Julias". Available in Slack-connected workspaces.
  • Manage Viktor access from chat — Admins can ask Viktor to block people, edit allowlists, change guest access, update Slack Connect channels or revoke team invites. Each change is shown as a draft and only applies once an admin approves it.
September 30, 2026

GPT-6.1 Sol, Claude Sonnet 5.5, and #channel mentions in chat

Two new models are in the picker, the Balanced and Ultra presets moved to Claude Opus 5.5, and the chat composer can now reference Slack channels.

  • GPT-6.1 Sol and Claude Sonnet 5.5 — OpenAI's GPT-6.1 Sol is now selectable in the model picker with its reasoning and speed options, at the same price as GPT-6 Sol. Claude Sonnet 5.5 is also out of beta and available to every workspace.
  • Balanced and Ultra now run on Claude Opus 5.5 — The Balanced preset (and !fast) moved to Claude Opus 5.5 at low reasoning, and Ultra moved to Claude Opus 5.5 at high reasoning. Workspaces on either preset pick up the new model on their next message.
  • Reference Slack channels with # — Typing # in the web chat composer opens a list of the Slack channels you can read. Pick one to drop #channel-name into your message, so you can point Viktor at a channel without typing its name from memory.
  • Feature docs on viktor.com/docs — The docs now cover every user-facing Viktor feature, grouped by category.
September 29, 2026

A single-rail sidebar, a chat-first Viktor page, and multi-speaker audio

The sidebar and home page were redesigned around chatting with Viktor first, and Viktor can now generate multi-speaker dialogue audio with emotion tags.

  • Single-rail sidebar — The separate chat-history rail is gone. Nav items and your recent chats now live in one column (Home, Infinity, Tasks, then Workspace, Organization, and your chats), so switching between navigation and chat history no longer means two panels competing for space.
  • The dashboard is now the Viktor page — Opening a workspace used to land on a credits-and-rewards dashboard. It's now the Viktor page: starting a chat comes first, with the nav row reading "Viktor" instead of a separate Chat item. Once onboarding content is done, the page centers on the chat instead of leaving empty space around leftover cards.
  • Multi-speaker dialogue audio — Viktor's text-to-speech can now render a full back-and-forth between multiple voices in one call, and can use inline delivery tags like [whispers] or [laughs] for more expressive narration — useful for podcast-style clips or dialogue scenes instead of flat single-voice narration.
September 26, 2026

Admin DM restrictions, and richer integration connects in app chat

Workspace admins can now limit which teammates Viktor is allowed to DM in Slack, and connecting an integration from app chat shows a real connect card and picks the conversation back up once you're connected.

  • Limit who Viktor can DM — Settings → Permissions gets a new "Who Viktor can DM" control, laid out like the existing "Who can use Viktor": anyone in the workspace, or an admin-picked list. When restricted, every DM Viktor tries to start or post into — including outreach crons and group DMs — is checked against the list first, with a plain-language refusal explaining what's blocked and why.
  • Integration connects get a card in app chat — Asking Viktor to connect an integration in app chat used to get a bare Markdown link. It now shows a proper connect card (icon, name, description) for Pipedream, Composio, Zapier and MCP connects, and once you finish connecting, Viktor resumes the same conversation instead of leaving it hanging.
September 25, 2026

Email for Teams-only workspaces, and richer usage insights

Workspaces that only installed Viktor to Microsoft Teams can now send and receive email, and the Usage page compares periods and lets you pick a custom date range.

  • Email inbox for Teams-only workspaces — Viktor's email inbox (<prefix>@viktor-mail.com) used to be minted only through the Slack install; a workspace that only added Viktor to Microsoft Teams could neither send nor receive email. Teams-only workspaces now get their own inbox automatically, and the Emails settings page treats Teams installs the same as Slack.
  • Compare usage periods, and pick a custom range — The Usage page's credit chart now overlays the previous period as a dashed line and shows the percentage change ("+21% vs previous period"), and the period picker gains a custom date range option (up to 366 days) alongside the fixed windows.
  • List a Google Sheet's tabs directly — Viktor's Google Sheets tool can now list every tab's name, ID, and size in one call instead of reading the whole sheet first, so asking Viktor about a spreadsheet's structure is faster.
September 24, 2026

Chat media albums and Google Ads target ROAS

Images and videos in chat now group into a real album with a working video player, and the Google Ads MCP can set target ROAS on an ad group directly.

  • Chat media albums — Multiple images and videos attached to a chat message now render together as a compact album with a working video player, instead of stacking one file per row with a bare "Open"/"Download" link.
  • Google Ads: target ROAS on ad groups — The Google Ads MCP can now set target ROAS on a single ad group directly, and refuses with an explanation instead of silently no-op'ing when the ad group's bidding strategy wouldn't apply the change.
September 23, 2026

Claude Opus 5.5 and GPT-6 join the model lineup

Claude Opus 5.5 and OpenAI's GPT-6 Sol/Luna are now in the model catalog, and 26 more official integrations — including Kajabi, OpusClip, HoneyBook, vidIQ, Avoma and FirstPromoter — joined the catalog as one-click connects.

  • Claude Opus 5.5 and GPT-6 Sol/Luna — Both new model families are live in the catalog with full pricing and billing support. Smart now runs on Claude Opus 5.5, and Cheap runs on GPT-6 Luna — at the same price you paid before, since the customer-facing rate card didn't change.
  • 23 new integrations — Kajabi, OpusClip, HoneyBook, vidIQ, Ubersuggest, Aloware, Akiflow, Magnific, Sunsama, and 14 more vendors are now searchable, one-click catalog cards instead of manually pasted custom MCP URLs.
  • Avoma, FirstPromoter and Votel — Three more official remote MCPs get one-click OAuth cards: search Avoma meeting transcripts, notes and scorecards and update outcomes (Organization/Enterprise plan or API Access add-on required); manage FirstPromoter affiliate programs, promoters and commissions; build and publish Votel AI websites and manage contacts, agents and campaigns. All three can be shared with your team like any other catalog integration.
September 22, 2026

Clay joins the integrations catalog

Connect Clay's official remote MCP directly from the integrations catalog — no more hunting down the URL and OAuth flow yourself.

  • Clay integration — Clay now has an official catalog card under CRM/Marketing, with a one-click OAuth connect. Previously, teams had to discover and configure Clay's MCP server URL manually; it's now a predefined, team-shareable integration alongside your other tools.
September 16, 2026

Wide tables and code blocks, expanded in place

Wide tables and code blocks in chat now expand to the full pane width on their own, without widening the whole conversation.

  • Expand wide tables and code blocks in place — Tables and code that used to be squeezed into the reading column can now expand independently to the full pane width, while your prose and the composer stay centered. Each block gets a bordered look and a theme-matched Expand/Collapse action next to a separate Copy button.
September 15, 2026

A wider chat, and a way into the Viktor Community

Pick a Wider or Full width chat from the header or Settings, and find the Viktor Community from a new link in the site footer.

  • Chat window size — Chat used to read in the same fixed-width column no matter your screen. A new "Chat window size" preference lets you pick Default, Wider, or Full width from a button in the thread header or from Settings → Behavior. Only the message column grows — the composer stays put.
  • A way into the Viktor Community — A new Resources → Viktor Community link in the site footer opens /community, where eligible workspaces can request an invite to join.
September 12, 2026

Your dashboard, your work

The dashboard is now a personal home page with your chats, runs, and pages up front, plus an emoji picker in chat and an installable API adapter for ACP clients.

  • A personal home page — /dashboard used to show the same workspace stats to everyone. It now leads with your own recent chats, your scheduled runs and how they went, and your published pages, with credits and rewards up top; admins get a Workspace summary at the bottom.
  • Emoji search in chat — Type a colon in any chat composer to search emoji by name, see your recently used ones, and pick without losing your draft or cursor position.
  • An installable Viktor adapter for ACP clients — Use Viktor from any Agent Client Protocol client without pulling this repository, via a local adapter for the Compat API plus a Quick Start covering install, scoped keys, and approvals.
September 11, 2026

Keenable joins your integrations

Connect your own Keenable account so Viktor can search the live web and fetch pages as clean text.

  • Keenable web search integration — Keenable, a search service built for AI agents, is now a card in the integrations panel for every workspace. Connect it with your own Keenable API key and Viktor gains two new tools: live web search and fetching a page as clean text.
September 10, 2026

Talk over Viktor and he stops

A new voice setting cuts Viktor's playback the instant you start talking over him, instead of a second later.

  • Quiet Viktor when you talk over him — In a live voice call (Talk to Viktor and Infinity mode), Viktor used to keep talking for about a second after you started speaking over him, making it hard to take the floor. A new switch in Settings → Voice, off by default, drops his playback the moment your microphone hears you — about a second before the model itself would have stopped.
September 9, 2026

Queue a follow-up, pick a cheaper model, push reasoning higher

Chat now lets you queue a follow-up instead of steering into a running turn, a new Cheap preset routes simple work to a lower-cost model, and Claude models offer two new reasoning levels.

  • Queue or steer follow-ups mid-run — Sending a message while Viktor is still working used to always steer straight into the running turn. Now web chat lets you choose: Steer sends it into the run at the next step, Queue holds it and sends once the run finishes — handy for "then do X" follow-ups. Enter keeps your remembered default; Cmd/Ctrl+Shift+Enter does the other one for a single message.
  • A Cheap model preset — The composer and settings model pickers now have a fourth preset, Cheap, backed by GPT-5.6 Luna, alongside Ultra, Smart and Balanced — a lower-cost option for simple lookups and mechanical work.
  • Higher reasoning levels on Claude models — Claude Fable 5.1, Fable 5, Opus 5, Opus 4.8 and Sonnet 5 now offer xhigh and max reasoning effort (Opus 4.6 adds max), available anywhere you pick a reasoning level — default model settings, !fast/!deep overrides, and the composer picker.
September 8, 2026

GPT Image 2.5 is the new default image model

Viktor's default image model is now OpenAI's GPT Image 2.5 Sunburst — sharper detail, more natural lighting, edits that leave the rest of the picture alone — with GPT Image 2.5 Flare for quick iterations, at about a quarter of the cost of GPT Image 2.

  • GPT Image 2.5 Sunburst replaces GPT Image 2 — Image generation and editing now default to gpt-image-2.5-sunburst, OpenAI's most capable image model: sharper details, richer textures, better fidelity to the people and products in your reference photos, and edits that change only what you asked for. Nothing to change on your side — existing requests, aspect ratios, and transparent backgrounds all carry over.
  • GPT Image 2.5 Flare when quality doesn't matter — For a throwaway, a just-for-fun image, or a rough prototype, Viktor can reach for gpt-image-2.5-flare: same price, a few seconds faster.
  • Cheaper per image, and a cheaper marketplace cover — GPT Image 2.5 uses about a quarter of the tokens per image at the same token prices, so each generation or edit costs roughly a quarter of what it did. Generating an AI cover for a marketplace skill listing now costs 12 credits instead of 40.
September 8, 2026

Rename your chats

Chats in the web app can now be renamed in place, right from the sidebar.

  • Rename a chat from the sidebar — Every chat row now has a "…" menu (also reachable by right-click) with Pin, Rename and Archive. Rename edits the title in place — Enter or clicking away saves it, Escape cancels — and the new name syncs to your other devices. No more being stuck with whatever the auto-titler guessed.
September 7, 2026

Recommended integrations for everyone, and a clearer approval card

The integrations page now recommends tools to every Slack-installed workspace, and approval requests in chat lead with the sentence that matters.

  • Recommended integrations, for every workspace — The /integrations page now shows a Recommended section for every Slack-installed workspace, refreshed weekly from the Slack messages Viktor already stores (no extra Slack or model calls). Previously this only worked for a small test group and expired after 30 days.
  • Approval cards lead with the sentence, not the JSON — When Viktor needs a yes on a tool call, the card now opens with a plain-language caption ("Google Calendar · Create event") and the agent's own sentence about what will happen, with the raw arguments tucked behind a "What it will send" toggle instead of sitting in front by default. "Always approve this tool" moved into the Approve button's menu so it can't be clicked by accident.
September 5, 2026

The Skills explorer is now the only Skills page

The file-explorer redesign of the Skills page is fully rolled out, and skills are now ordered by how much you actually use them.

  • Skills page explorer, for everyone — The tree-and-reader redesign of the Skills page (folders and files on the left, the skill itself readable on the right) is now the only Skills page; the older tabbed layout is gone for good.
  • Ordered by what you actually use — Collections and the skills inside them are now ranked by how often you read them, so your most-used tools surface first instead of sitting wherever the alphabet happened to put them.
September 4, 2026

Change a Space's URL anytime, and speaker-labeled transcripts by default

Spaces can now switch their address without a redeploy and speech-to-text separates speakers automatically.

  • Change a Space's URL anytime — Workspaces can now switch a deployed Space to a new address from Settings, without a redeploy or any downtime. Previously this required an internal operator to run a script.
  • Speaker-labeled transcripts by default — The transcription tool now separates speakers automatically, turning a multi-person recording into labeled turns (Speaker 1, Speaker 2, ...) instead of one undifferentiated block of text.
September 3, 2026

A clearer Emails settings page, and readable URLs for Pages

Emails settings got a redesign around one sender list, and workspaces can now move their published Pages to a readable web address.

  • Emails settings, redesigned — The Emails settings page now leads with Viktor's inbox address in a copyable field, and merges allowed domains and addresses into one "Allowed senders" list that tells you what typing an email or a domain will do before you confirm it. An empty allowlist now warns you and offers to allow your whole company domain in one click.
  • Readable Pages URLs — Workspaces can now switch their published Pages from the legacy random-string address to a readable {workspace-slug}.viktor.page root, matching the readable Space URLs shipped last week. Old links keep working via redirect.
September 2, 2026

Claude Fable 5.1 is now available, and is the new Ultra default

Claude Fable 5.1 is live for everyone, and Viktor's Ultra model preset now runs it by default.

  • Claude Fable 5.1 — Anthropic's Claude Fable 5.1 is now available to every workspace, no beta flag required. The Ultra preset now serves Fable 5.1 by default, replacing Fable 5.
September 1, 2026

See model costs by reasoning level, and confirm before switching everyone

The model picker now shows reasoning-specific cost estimates, and changing a workspace's default model needs confirmation first.

  • Cost by reasoning level — The model picker (default model, voice, commands, and scheduled tasks) now shows a cost estimate for each reasoning level of a model, based on real production task costs, instead of one flat guess per model.
  • Confirm before changing the workspace default model — Changing the default model for a workspace with more than one member now opens a confirmation dialog naming the old and new model and how many teammates it affects, so one accidental click can't switch the whole team's model.
August 31, 2026

Bring your own OpenRouter key for 300+ models

Connect your own OpenRouter account for direct access to 300+ AI models, plus faster approvals and cleaner Space URLs.

  • Native OpenRouter integration — Connect your own OpenRouter API key and Viktor can chat with any of OpenRouter's 300+ models, billed to your own OpenRouter credits, with a model browser and key-status check built in.
  • Grouped approval cards in app chat — A burst of tool calls needing approval now folds into a single card instead of a stack, with an "Always approve this tool" option — bringing app chat's approval flow to parity with Slack.
  • Readable Space URLs — New Viktor Spaces get a human-readable address (e.g. workstreams-zeta.viktor.space) instead of a random string, making them easier to share and recognize.
August 30, 2026

Viktor can post directly to your Facebook Page

With Meta Ads connected, Viktor can now create, edit, and delete posts on your Facebook Page — not just draft unpublished ad creatives.

  • Facebook Page posts — With a Meta Ads connection, Viktor can now publish a visible post to your Facebook Page, edit its text, or delete it — going beyond unpublished ad creatives to real Page feed writes. Every create, edit, or delete asks for your approval first, and a successful post always comes back with a link so you can check it live on Facebook.
August 29, 2026

Pages: manage, share, and version what you publish

Viktor's generated pages are now fully live, with delete, duplicate, rename, sharing, and version history.

  • Pages management — Viktor's generated pages feature is now live for everyone. You can delete, duplicate, and rename pages, hand off ownership to a teammate, share a page via link or QR code, and browse a version history with one-click restore. The pages list shows who created what, who can access it, and how many views it's gotten.
  • Collapsible sidebar — The chat sidebar in web chat can now be hidden, not just resized. Toggle it with the sidebar button or ⌘B / Ctrl+B; the setting is remembered next time you open Viktor.
August 27, 2026

Guests get direct edit access on Viktor-created calendar events

When Viktor creates a Google Calendar event, invited guests can now edit it directly instead of only proposing changes.

  • Direct edit access for calendar guests — When Viktor creates a Google Calendar event, guests (including the person who asked for it) can now edit the event directly — move the time, update details — instead of only being able to propose changes. Viktor's connected account stays the organizer; this only changes what guests can do.
August 26, 2026

Transparent backgrounds for generated images

Ask Viktor for a transparent PNG or WebP and GPT Image 2 will generate cutouts, logos, and stickers with real alpha — no manual background removal.

  • Transparent image backgrounds — Viktor can now generate images with a transparent background using GPT Image 2, its default image model. Just ask for a cutout, logo, or sticker as a transparent PNG or WebP and Viktor requests it directly from the model instead of removing the background afterward. Existing image requests are unaffected — transparency is opt-in.
August 19, 2026

Supermemory in the integrations catalog

Connect your Supermemory account over OAuth so Viktor can search and add to your personal memory store.

  • Supermemory integration — Supermemory is now a card in the integrations catalog, connected over OAuth to Supermemory's hosted MCP server. Once connected, Viktor can search your existing memories and pull them into whatever you're working on. Connections are private to you by default, and anything that writes or forgets a memory asks for your approval first. Viktor's own workspace memory is untouched — this is an extra store you already own, not a replacement.
August 12, 2026

Wispr Flow meetings, and memory on Microsoft Teams

Connect Wispr Flow's Notetaker so Viktor can read your meeting notes, and workspace memory now works on Microsoft Teams.

  • Wispr Flow integration — Wispr Flow is now a first-class card in the integrations catalog, connected over OAuth to Wispr's official Notetaker MCP. Once connected, Viktor can list your recorded meetings and pull their notes, summaries and action items into whatever you're working on — no setup beyond clicking Connect.
  • Workspace memory on Microsoft Teams — Memory is no longer Slack-only. Teams workspaces get the same three pieces Slack has: relevant memory injected into the first turn of a new thread, memory_search available to Viktor mid-task, and the nightly pass that turns conversations into durable workspace knowledge.
August 11, 2026

Custom domains, and Seedance 2.5 video

Serve Spaces and published pages on your own domain, and generate 30-second video clips with Seedance 2.5.

  • Custom domains for Spaces — Any workspace admin can now point a domain they own at a Space from its Settings tab, no waitlist or flag. Viktor walks you through the DNS records, provisions the certificate, and keeps whatever access policy the Space already had. Published pages get the same treatment: ask Viktor to add a domain for your pages and one hostname serves your whole viktor.page namespace, with per-page access carried over.
  • Seedance 2.5 for video generation — The default text-to-video model is now Seedance 2.5: single-shot clips up to 30 seconds at 720p, and up to 30 reference images to steer the look. A cheaper 480p variant is available for drafts, and Seedance 2.0 stays selectable when you want the lower price.
August 8, 2026

Manage shared skills from the browser, and run them with /

Upload, edit and download your workspace's shared skills without leaving the Skills page, trigger any of them with a slash command in chat, and use the OpenAI-compatible API from Microsoft Teams.

  • Upload, edit and download shared skills — The Shared Skills tab on the Skills page now does more than show you what Viktor knows. Anyone in the workspace can download a skill as a zip with its full files, admins can edit any text file in place — including SKILL.md — and a new Upload skill flow takes a folder or zip and validates it file by file before it lands. Edits take effect on Viktor's next turn.
  • Shared skills as slash commands — Typing / in the chat composer now lists your workspace's shared skills alongside system commands, so picking one sends it straight to Viktor. Autocomplete follows the / wherever it sits in your draft, and recognized commands get highlighted as you type and in the sent message.
  • Microsoft Teams on the API — The OpenAI-compatible and public APIs now work for Teams workspaces exactly as they do for Slack: chat completions, responses, messages, threads and runs all resolve your Teams identity and run with your connections. No setup or opt-in needed.
August 7, 2026

Archive chats and search everything from ⌘K

Chats can be archived out of the sidebar, and ⌘K now searches your chat history and starts a new chat from whatever you typed.

  • Archive chats — Archive a chat to clear it out of the sidebar, browse everything you've put away in the Archived chats view, and unarchive when you need it back. Works in the web app.
  • ⌘K searches your chats — The command palette now searches your chat history alongside pages, settings and actions, so there's one search instead of two. Typed a message rather than a query? ⌘↵ starts a new chat with it from any screen, without navigating to chat first.
  • Slash commands in the composer — Typing / in the chat composer opens a command menu. First one in: /usage, which pops the workspace usage dashboard for admins without leaving the conversation.
August 6, 2026

Chat in the web app, task renaming & Slack-native invites

Chat is now available to everyone in the Viktor web app, scheduled tasks can be renamed, and team invites arrive as a Viktor DM in Slack.

  • Chat in the web app — Chat is out to all users at viktor.com: full conversations with Viktor outside Slack, with searchable history, auto-titled threads, unread indicators, image generation and keyboard shortcuts. Same workspace, same memory, same integrations — a second door into the same Viktor.
  • Rename scheduled tasks — Scheduled tasks can be renamed after they're created, from the task detail page or the calendar edit dialog. Admins, the task creator, and whoever requested the run can edit the name.
  • Slack-native team invites — The team invite field now suggests people from your connected Slack workspace, and Viktor delivers the invite as a DM instead of an email. External addresses and Microsoft Teams workspaces still get the email invite.
August 1, 2026

Viktor on Discord

Viktor now works in Discord, and Slack guest access can be scoped to specific people and channels.

  • Discord — Connect the new "AI Coworker (Discord)" integration and the same Viktor shows up in your Discord DMs and channels: same memory, same skills, same integrations as in Slack. No separate account needed — it's the one workspace, in a new room.
  • Scoped guest access — Slack guest access is no longer all-or-nothing. Admins can allow only specific guest accounts to trigger Viktor, and confine guests to chosen channels, so a client or contractor in a shared channel gets exactly the access you intend.
July 31, 2026

Developer docs, usage API & new MCP integrations

Full API and MCP documentation is live on viktor.com, the public API can now report usage and credits, and 19 popular MCP servers joined the integration catalog.

  • Developer documentation — viktor.com/docs now covers the public API, the MCP server, and the OpenAI/Anthropic-compatible endpoint, plus getting-started guides for connecting tools and scheduling tasks. Endpoint tables are generated from the API spec, so they stay in sync with what ships.
  • Usage & credits API — Three new public API endpoints report your credit balance with a burn-rate forecast, windowed credit totals, and per-day usage broken down by one-off runs, scheduled tasks, media, and Spaces. Grant a key the usage:read scope to build your own spend dashboards or alerts.
  • 19 new MCP integrations — Higgsfield AI, Otter.ai, Context7, Superhuman Mail, SE Ranking, AgencyAnalytics, SocialPilot, Consensus, Plaud, JobTread, AWS Knowledge, OpenArt and more are now one-click entries in the integration catalog instead of custom MCP URLs.
July 30, 2026

MCP server

Connect any MCP client to Viktor with your API key — Claude, Cursor, OpenAI Agents SDK, and more.

  • MCP server — Viktor's public API now includes an MCP endpoint at api.viktor.com/mcp. Point any MCP-compatible client — Claude Desktop, Cursor, OpenAI Agents SDK — at it with your API key and drive full agent runs, manage threads, and retrieve results without writing REST calls. The server supports 14 tools including ask_viktor for one-shot agent runs with real-time progress.
July 29, 2026

Kimi K3 & public API

Moonshot's Kimi K3 is now available in the model picker, and Viktor's OpenAI-compatible API is generally available for all workspaces.

  • Kimi K3 — Moonshot's 2.8-trillion-parameter reasoning model joins the model picker with 1M-token context and always-on chain-of-thought. Choose between low, high, and max reasoning depths depending on the task — it runs at roughly half the cost of comparable frontier models.
  • Public API — Viktor's OpenAI-compatible API is now generally available. Call it using the OpenAI SDK, Anthropic SDK, or any compatible client to run Viktor programmatically — same models, tools, and integrations as the chat, accessible with a personal API key from Settings.
July 28, 2026

App chat: search, unread badges & shortcuts

Find past conversations with full-text search, see which threads have new messages, refine generated images, and navigate with keyboard shortcuts.

  • Conversation search — A search bar in the sidebar lets you find any past thread by keyword. Threads are also auto-titled from the first exchange, so you can scan your history at a glance.
  • Unread badges — Thread rows now show an unread indicator when there are new messages you haven't read yet, so you always know which conversations need attention.
  • Image refinement — Generated images include a refine action in the lightbox — click it to start an edit prompt that uses the original as a reference.
  • Keyboard shortcuts — Navigate between threads, open compose, and trigger common actions with keyboard shortcuts. Customize bindings in the new Keyboard Shortcuts page under Settings.
July 25, 2026

Claude Opus 5

Anthropic's most powerful model is now available in Viktor's model picker.

  • Claude Opus 5 — Anthropic's latest flagship model, launched July 23, is now available in the model picker for all workspaces. Select it when you need the deepest reasoning and most capable generation Anthropic offers — it runs on the direct Claude API with a 1 M-token context window.
July 21, 2026

Admin control over Space access & Meta Ads budget schedules

Workspace admins can now edit Space access policies, and Viktor can manage High Demand Period budget boosts on Meta Ads.

  • Workspace admins can edit Space access — Access policies for a deployed Space can now be changed by workspace admins as well as the Space's creator, so managing who can open a Space no longer depends on one person. Regular members remain view-only.
  • Meta Ads budget schedules — Ask Viktor to create, list, and delete budget schedules (Meta's High Demand Periods) on your campaigns and ad sets — time-bounded budget boosts, handled directly through the Meta Ads integration.
July 18, 2026

Viktor in your language & faster navigation

Use Viktor's interface in your language — 28 languages supported — plus a new ⌘K command menu, a Team page in the sidebar, and billing-period views on the Usage page.

  • App language — Use Viktor's interface in your language: 28 languages supported, including separate Español (España) and Español (Latinoamérica). Set yours in Settings → Personal → App language.
  • ⌘K command menu — Get around Viktor faster with the new command menu — press ⌘K to open it.
  • Team page — Your team now has its own page in the main sidebar, so it's one click away.
  • Billing periods on the Usage page — The new period picker on the Usage page lets you view usage for your current or previous billing period, plus recent ranges like the last 7 or 30 days.
July 13, 2026

Manage your plan from Slack

Pick a plan, upgrade, and enable auto top-ups directly from Slack — payment for new subscriptions completes in your browser.

  • Slack in-app billing — You can now pick a plan, upgrade, and enable auto top-ups directly from Slack. New subscriptions hand you a secure Stripe Checkout link to complete payment in your browser; upgrades and auto top-ups happen without leaving your workspace. Auto top-up credits are charged at the same rate as the credits in your plan. One-time top-ups remain available on the web.
