Message Viktor in Slack like you'd message a teammate. "Summarize everything new in Mattermost from the last 24 hours and flag what needs a reply." "Draft a reply to the latest Mattermost thread about the renewal and send it after I approve." Plain English, any tool.
Viktor opens Mattermost, 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 Mattermost AI agent is an AI that connects to your Mattermost account and completes work in it - it doesn't just answer questions about Mattermost, it takes the actions. Viktor is that agent: an AI employee that works in Mattermost 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 Mattermost actions, chains them with the other 3,200+ tools it connects to, and asks for approval before anything sensitive runs.
