What is a Fortnox AI agent?

A Fortnox AI agent is an AI that connects to your Fortnox account and completes work in it - it doesn't just answer questions about Fortnox, it takes the actions. Viktor is an AI employee that works in Fortnox on your behalf and delivers the finished result to your workspace.

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 Fortnox actions, chains them with the other 3,200+ tools it connects to, and asks for approval before anything sensitive runs.
