Best AI tools for sales teams working in Slack (2026)

By Kris Newlin · Updated October 25, 2026

Key Takeaways

The best AI for sales in 2026 does the work in the place where the team already talks. For prospecting, pipeline hygiene and CRM updates that run from Slack, Microsoft Teams or the web app at app.viktor.com, start with Viktor, the AI employee who connects to your CRM and asks for approval before he changes a record. The specialist products below each cover a narrower job:

• Viktor: One AI employee for the whole team. He works in Slack, Microsoft Teams or the web app, across 9,800+ connected tools.
• Gong: Call recording, deal warnings and forecasting. Slack and Teams mostly receive its notifications.
• Clari (now part of Salesloft): Forecasting and pipeline inspection for revenue leaders.
• Outreach: Sequencing teams that want to accept or edit deal suggestions from Slack.
• HubSpot Breeze: HubSpot CRM customers who want to update records by mentioning Breeze in Slack.
• Apollo.io: Outbound teams that need a contact database and sequencing in one product.

AI for sales: the short answer

AI for sales covers three recurring jobs: finding and researching prospects, keeping the pipeline accurate, and keeping the CRM current. Many products in this category handle one of those jobs inside their own app. Some, such as Gong and Clari, mainly send alerts to Slack or Teams, and the rep opens the app to do the work.

Viktor does the work. After a call, a meeting event trigger starts him where the platform supports it. He posts deal stage, next step and close date updates as an approval card: Approve writes them to Salesforce or HubSpot, Reject leaves the record unchanged. See what an AI employee is.

A specialist product fits better when the need is narrow and already lives in one system. Examples are call coaching in Gong, forecast roll-ups in Clari, or record edits in a HubSpot-only stack.

Sales workflow automation: what AI runs, what people approve, what stays human

AI automates the most time-draining sales workflows (account research, lead enrichment, pipeline scans, CRM updates and follow-up drafts) by doing the work from a trigger, such as a finished call, a new lead or a weekly schedule, and asking a person to approve anything that changes a record or reaches a buyer. Sales workflow automation therefore splits into three tiers. AI runs the research and scanning work on its own, people approve anything that writes to a record or reaches a buyer, and people keep the judgment calls.

Four technologies sit underneath these tools. Generative AI, built on large language models, drafts emails, briefs and call summaries. Machine learning finds patterns in past deals, and predictive models turn those patterns into lead scores and deal risk warnings. Natural language processing reads call transcripts and email threads to pull out next steps, objections and sentiment. Agentic AI chains these steps together, so a product can read the CRM, decide what to update and post the change for approval instead of only answering a question.

Viktor, the AI employee, runs the first tier on his own and posts second-tier changes as approval cards, while human-only work stays with sellers so people spend time on work only they can do.

How we picked these tools

Every product on this list does at least one of the three sales jobs above, and its own help center, release notes or press releases from 2025 or 2026 document how it works in Slack or Microsoft Teams. Each product is compared on four questions:

• Where the work happens: Can a rep ask a question or approve a change inside Slack or Teams, or does the chat app only receive a notification?
• Write access with review: Does the product change CRM fields, and does a person approve the change first?
• Scope: Does it cover one sales job or several across different systems?
• Pricing model: Does the vendor charge per seat, per credit, or from shared workspace credits?

Claims about competitors come from those vendors’ documentation, with dates where the pages give them. For Slack tools outside sales, see this roundup of Slack AI tools.

The best AI tools for sales teams

Viktor comes first as the AI employee. The five specialist products follow, each with the situation where it fits.

1. Viktor: the AI employee who works your pipeline from Slack

Viktor is the AI employee who lives in Slack and Microsoft Teams, connects to 9,800+ tools, and does the work. Teams that don’t use either chat app can start in the web app at app.viktor.com, and Discord teams can run him in their server. The company hires one Viktor, so anyone on the sales team can DM him or mention him in a channel, and he keeps what he learns about accounts, deal stages and team preferences in workspace memory.

His sales work runs through the CRM you already pay for: HubSpot, Salesforce and Attio are among the 9,800+ tools in the integrations directory, and most connect with one-click OAuth. When a tool is missing but has an API or MCP server, he can usually build the connection himself. He plans each job on his own cloud computer and posts the result in the thread, so nobody has to build a workflow or maintain infrastructure for him.

Three features make him useful for pipeline hygiene:

• Scheduled tasks: A Friday pipeline update or a Monday morning brief is set up once in plain English and then runs every week.
• Event triggers: A message, a meeting, a won deal, a submitted form or a webhook can start a job. Availability differs by platform.
• Approval cards: Viktor is an AI employee who waits for approval before he changes a record. Sensitive actions post a card with Approve and Reject buttons, and a rejected action does not run. Admins can mark any tool as needing approval or as forbidden.

Microsoft Teams support has been generally available since 18 June 2026. In Teams he handles DMs, channel mentions, group chats, followed threads, approval cards, files and scheduled tasks.

Slack has features Teams lacks, including canvases, Lists and Slack Connect. In Teams, meeting transcripts are available only where the tenant allows them. In Slack, his searches respect what the person asking can see.

Hampton’s results show what owned work looks like at scale. In 44 days, Viktor connected 24 tools, took over reporting, built 12 dashboards and took on 26 recurring jobs a week, and Hampton avoided $440K in planned hires. Those are Hampton’s figures, not a forecast for other teams (read Hampton’s story). Viktor is rated 4.8 on G2.

Pick one sales job, such as the Friday pipeline update, and hand it to Viktor free. Signup includes up to $100 in credits and needs no credit card.

2. Gong

Gong is a revenue intelligence platform built around recorded calls. Its AI Deal Monitor shows eight warnings on deal boards, including Ghosted, No power and Stalled in stage, and AI Deal Predictor scores each open deal against the rest of the pipeline. Gong’s help center says AI Data Extractor pulls insights from calls and can optionally write them to the CRM fields a team chooses, and “reps do not need to do anything for the fields to be updated.”

Predictive lead scoring ranks leads or deals from activity and CRM signals, and per Gong’s help center, AI Deal Predictor applies that idea to open deals using 300+ signals. Its score is a percentile rank against other open deals, not a probability. Deal risk warnings fire on activity or a lack of it, such as no emails or calls logged for a set period, a risky prospect email, or too few contacts on the deal, and they draw on all interactions from one week before the opportunity is created until the deal closes.

A score or warning should trigger a human action: a rep or manager decides the next step. On the coaching side, AI Call Reviewer scores calls against scorecards, and AI Trainer runs AI role-play practice that is available with Gong Enable. For onboarding, scored calls and AI summaries give new reps examples of strong discovery calls to study before they run their own.

Most of Gong’s chat-app features are notifications:

• Slack: Streams post new matching calls to a channel. Reps can share calls and reply to comment notifications, and forecast reminders reach AEs one hour before the forecast is due.
• Teams: The Gong Notifications app posts mentions, comments, call shares and stream updates, but it does not post to private or shared channels.

Gong’s help center does not document asking Gong questions inside a Slack channel or DM. Questions go through Gong Assistant on call pages, the Account console and Search, or through Gong’s read-only MCP server in Microsoft Copilot, ChatGPT and Claude.

Gong’s pricing page says licenses are “priced per user” plus a platform fee based on the number of users, and it publishes no dollar amounts (checked October 2026).

Choose Gong when call recording, coaching and deal warnings matter most, and Slack or Teams only needs to deliver alerts.

3. Clari

Clari and Salesloft completed their merger on December 3, 2025, and since September 2, 2026 the two have operated as one company under the Salesloft brand, with Clari Forecast keeping the Clari name. Forrester wrote in August 2025 that “Clari dominates forecasting.” An April 14, 2026 release lets managers and reps create Salesloft tasks and send AI follow-up emails from Clari Forecast and Clari Inspect.

Clari’s chat-app features run through Clari Copilot, and Clari’s July 2025 notification guide lists pre-call alerts and post-call alerts that cover call summaries, action items, smart follow-ups and CRM field updates, delivered in Slack or Teams. Clari’s help center says Smart Summaries are available only to users with the Slack integration enabled, and its documentation does not describe Ask Clari answering questions inside Slack or Teams.

Choose Clari when forecast accuracy is the main problem, especially if the team already runs Salesloft.

4. Outreach

Outreach combines sequencing, conversation intelligence through Kaia, and AI features sold through its Amplify package. Its October 2026 release notes say Omni is “now available directly in Slack,” either in the Outreach app’s Chat tab or by inviting @Outreach into a channel. Reps can ask Omni to list stuck opportunities, summarize call transcripts or draft follow-up emails, but Omni in Slack requires the Amplify package, and only the person who started a thread can ask follow-up questions in it.

Deal Agent posts suggested opportunity updates from Kaia calls to Slack, where reps can accept, reject or edit them, though action buttons work only for free-text fields. Outreach’s FAQ says Teams notifications “don’t support accepting, editing, or rejecting an update directly,” so reps open Outreach to finish the change. Smart Email Assist drafts emails that the rep reviews before clicking Send.

Choose Outreach when reps already sequence and record calls in Outreach and want to act on deal suggestions from Slack.

5. HubSpot Breeze

HubSpot’s help article on using Breeze Assistant in Slack, last updated October 19, 2026, says users can mention Breeze in a channel or DM to search, summarize, create and update records, including bulk changes. Before any CRM update, Breeze shows a confirmation card listing the proposed changes. HubSpot’s Slack Marketplace listing still labels this feature “Now in beta.”

• Teams: Support is narrower. HubSpot’s documentation does not describe Breeze chat inside Teams. A separate “Microsoft Teams for Breeze” connector makes Teams messages searchable from Breeze inside HubSpot.
• Outbound: The Prospecting Agent is available on Sales Hub Starter, Professional and Enterprise and uses 100 HubSpot Credits per lead (checked October 2026). It can run in “Review emails” mode or “Send without review” mode.
• Pricing: HubSpot charges per seat plus HubSpot Credits, and each paid tier includes a monthly credit allotment (checked October 2026).

Choose HubSpot Breeze when HubSpot is the CRM, Slack is the chat app, and the main need is record updates and summaries.

6. Apollo.io

Apollo’s homepage advertises 240M+ contacts and 30M+ accounts, and its native Slack app is available on all Apollo plans. From Slack, reps can find and research prospects, enrich contacts, add them to lists and sequences, ask about sequence reply rates, and pause a sequence. On Professional and Organization plans, scheduled runs for lead discovery, sequence creation and sequence optimization send recommendations to Slack, where reps approve the next step in the thread, and using Apollo’s AI in Slack requires a paid Slack plan.

Apollo documents no native Teams messaging integration. Teams appears in its docs as a meeting-recording source and as a listed workflow integration without documented actions. Apollo publishes per-seat plans that include credits (checked October 2026).

Choose Apollo.io when the team needs contact data and outbound sequences in one product and works in Slack.

AI sales tools compared

The table below compares Viktor, Gong, Clari, Outreach, HubSpot Breeze and Apollo.io on chat-app support and best fit:

What AI for sales looks like in a rep’s week

These four Viktor jobs show the difference between receiving an alert and getting finished work.

Pre-call research in two minutes

Say a rep DMs Viktor before a 2 p.m. call: “Brief me on Acme.” Viktor reads the account and open deal in the CRM, the recent email threads and notes from the last call in the connected tools. He posts a short brief in the thread covering who attended last time, what they objected to, and what the rep promised to send, and for the whole team the same job runs as a scheduled morning brief that lists each rep’s meetings for the day.

LinkedIn’s 2025 “ROI of AI” research, based on an Ipsos survey of 1,250 sales professionals, found that 38% of sellers who use AI to research leads and companies save over 1.5 hours per week.

CRM updates nobody has to type

In Validity’s 2025 survey of 602 CRM users and administrators, 76% said less than half of their organization’s CRM data is accurate and complete.

Viktor handles two pieces of that problem. The first is the post-call update described in the short answer at the top: after each call he posts an approval card, and only an approved change reaches Salesforce or HubSpot.

On Fridays, Viktor runs a scheduled task and posts the pipeline update to the sales channel. He lists open deals with no next step, close dates already in the past, and deals with no logged activity for two weeks. He then fixes the records each owner confirms in the thread.

Follow-up drafts that go through the rep first

After a call, Viktor drafts the follow-up from the notes and posts it in the thread, the rep edits it there, and Viktor sends it only after the rep approves. Keeping a person in that step protects the domain, since Google’s sender guidelines tell senders to keep reported spam rates below 0.10% and avoid ever reaching 0.30%. Forrester warns that AI outreach sent continuously across thousands of accounts “does not eliminate the spam problem; it further industrializes it” (Forrester).

For the full workflow, see the same-day follow-up guide.

Worked example: from new inbound lead to an approved first touch

Outbound sales and inbound follow-up share the same chain: source or receive the lead, enrich it, write the first touch, launch the sequence. Here is one way to hand that chain to Viktor in plain language:

1. Trigger: “When a new lead lands in HubSpot from the demo form, start.”
2. Enrich: “Look up the company’s size, industry and recent news, find the lead’s role, and add what you find to the HubSpot record as a proposed update.”
3. Draft: “Write a first-touch email that references one thing from the research and the page they converted on. Keep it under 120 words.”
4. Approval gate: “Post the record update and the draft in #inbound-leads as an approval card. Send nothing until the lead owner approves.”
5. Launch: “After approval, enroll the lead in the inbound sequence and log the email on the record.”

Steps 1 to 3 sit in the fully automatable tier, and steps 4 and 5 keep a person in charge of what reaches the buyer and the CRM.

How to choose an AI tool for your sales team

Choose based on where the work has to land and who approves it:

• Work spans several systems and starts in Slack or Teams: Viktor fits. He researches, updates the CRM and sends follow-ups across connected tools, and the rep approves each change from the thread.
• Call coaching and deal warnings are the gap: Gong fits, as long as Slack or Teams only needs to carry notifications.
• The forecast is the gap: Clari fits, especially for teams already on Salesloft.
• Reps live in Outreach sequences: Outreach fits, and its Slack action buttons work only on free-text fields.
• HubSpot is the CRM and Slack is the chat app: Breeze covers record edits from a mention. Its Slack feature is still labeled beta on the marketplace listing.
• The team has no contact data: Apollo.io supplies the database and the sequences.

Build versus buy

Three routes get an AI into the sales workflow, and they differ in setup effort, failure points and pricing model.

Viktor is the right pick for teams whose work spans several systems. A product built for a narrower scope may fit when the need lives in one system.

Guardrails for AI in sales

• Call recording consent: Tell participants a call is recorded. Some US states and countries require all-party consent. Tools such as Gong offer a consent page before meetings.
• Data that stays out of a model: Payment data, health data and credentials never belong in a prompt. Viktor’s API keys and tokens are added at runtime by a gateway, so the model never reads the credentials.
• Hallucinated claims in outreach: Nothing goes out before a rep approves it, and every claim about the prospect’s company gets fact-checked first. Forrester notes that hallucination and inference errors can distort company context and undermine seller credibility.

Check three things before you buy. First, confirm every write to the CRM passes an approval step you control. Second, confirm the product works in Teams to the same depth as in Slack if part of the company uses Teams. Third, compare pricing models: the build versus buy table above sets them side by side, and Viktor’s pricing page shows the current plans. His security details list SOC 2 Type 1 compliance, and customer data is never used to train models.

For a company-wide rollout, talk to the Viktor team about onboarding, security review and spend controls. Smaller teams can start with the Friday pipeline update today: sign up free with up to $100 in credits and no credit card required.

FAQ

How does AI for sales save reps time?

Salesforce’s 2026 State of Sales report surveyed 4,050 sales professionals from August through September 2025 and found that the average seller spends 40% of their time selling. AI takes over parts of the other 60%: account research, CRM entry and first drafts of follow-ups. Gartner reported on May 19, 2026 that AI saves sellers an average of 4.8 hours per week, yet the same release found that 72% of sales organizations report low reinvestment of that time into high-value selling, so decide up front where the saved hours will go.

Will AI replace SDRs and AEs?

AI augments sellers rather than replacing them. It takes over account research, CRM entry and first drafts of follow-ups, the tasks marketed as AI SDR work, while sellers keep discovery, negotiation and relationships. The SDR role shifts toward fewer, better-prepared conversations, with each outreach built on research that is already done. Viktor, the AI employee who takes that work off the team, leaves sellers to spend their time on work only they can do.

Does Viktor replace my CRM?

Viktor works inside the CRM you already pay for. He reads and updates records only with the access you grant, and the CRM remains your system of record.

Does Viktor work with Salesforce and HubSpot?

Yes. Salesforce and HubSpot are both among his 9,800+ integrations, along with Attio. Each connection can be shared with the whole workspace or kept private to the person who connected it and the people or groups they invite.

How is an AI employee different from a sales tool?

Most of the specialist products above are licensed per seat or per credit and do their main job inside their own app. The company hires an AI employee once for the whole team, so one Viktor takes requests from every rep and manager, remembers how the team sells, and returns finished work across the tools the team already uses. Viktor’s positioning line puts it as “Not a tool. A hire.”
