Message Viktor in Slack like you'd message a teammate. "Train a CustomGPT assistant on this batch of documents and test it with these questions." "Update the knowledge base behind our CustomGPT assistant with this new content." Plain English, any tool.
Viktor opens CustomGPT, runs the work, and posts back what changed. Sensitive actions wait for your approval. Everything is logged. You stop doing the work and start reviewing it.
A CustomGPT AI agent is an AI that connects to your CustomGPT account and completes work in it - it doesn't just answer questions about CustomGPT, it takes the actions. Viktor is that agent: an AI employee that works in CustomGPT on your behalf and delivers the finished result in Slack or Microsoft Teams.
Unlike workflow builders such as Zapier or Make, there is nothing to configure - no triggers to map, no workflows to maintain. You describe the outcome in plain English, and Viktor picks the right CustomGPT actions, chains them with the other 3,200+ tools it connects to, and asks for approval before anything sensitive runs.
CustomGPT lets you easily build your own chatbot with your own data.
Scoped API keys - Viktor stores your key securely, uses only the scopes you grant, and you can revoke it at any time.
Review-first approvals: sensitive CustomGPT actions wait for your sign-off before they run.
Isolated compute per team, encrypted in transit and at rest - and your data is never used to train models.
SOC 2 Type 1 compliant, with Type 2 and ISO 27001 in progress.
Yes. CustomGPT is one of the 3,200+ tools Viktor connects to, via a managed connector. Once connected, anyone on your team can put Viktor to work in CustomGPT from Slack or Microsoft Teams - no workflow builder, no code.
