Viktor opens Fidel API, 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 Fidel API AI agent is an AI that connects to your Fidel API account and completes work in it - it doesn't just answer questions about Fidel API, it takes the actions. Viktor is that agent: an AI employee that works in Fidel API 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 Fidel API actions, chains them with the other 3,200+ tools it connects to, and asks for approval before anything sensitive runs.
