Message Viktor in Slack like you'd message a teammate. "Clean this list of email addresses with Mailrefine and flag the invalid ones." "Check Mailrefine for our sender reputation and flag anything that could hurt deliverability." Plain English, any tool.
Viktor opens Mailrefine, 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 Mailrefine AI agent is an AI that connects to your Mailrefine account and completes work in it - it doesn't just answer questions about Mailrefine, it takes the actions. Viktor is that agent: an AI employee that works in Mailrefine 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 Mailrefine actions, chains them with the other 3,200+ tools it connects to, and asks for approval before anything sensitive runs.
