Viktor is an AI employee that connects to Cal.com with a scoped API key and helps you schedule meetings and manage appointment bookings, running 7 Cal.com actions for you like Get Booking, Cancel Booking, and Create Booking. Ask in plain English in Slack or Microsoft Teams; Viktor does the work in Cal.com and reports back. Setup takes about two minutes.

Message Viktor in Slack like you'd message a teammate. "Find a time that works for everyone and send a Cal.com booking link." "Check Cal.com for tomorrow's bookings and send me a morning summary." Plain English, any tool.
Viktor opens Cal.com, 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 Cal.com AI agent is an AI that connects to your Cal.com account and completes work in it - it doesn't just answer questions about Cal.com, it takes the actions. Viktor is that agent: an AI employee that works in Cal.com 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 Cal.com actions, chains them with the other 3,200+ tools it connects to, and asks for approval before anything sensitive runs.
Scheduling infrastructure for absolutely everyone.
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 Cal.com 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.
