## What is a Slack AI agent?

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