AI that does the work inside your own systems

AI connected where the work happens: in your documents, your email and the systems you already use. With approval and limits where they matter.

Extraction from documents and email

In MineKvitteringer, Google Document AI and Gemini read receipts and extract the data. New receipts are imported automatically from Gmail, Outlook and IMAP.

The same pattern fits invoices, forms and other documents that are typed in by hand today.

AI assistants that can act, within limits

With an MCP server, AI assistants such as Claude and Cursor can use your systems directly. FENO has an MCP server with 14 tools, where the spending limits are enforced on the server, not in the assistant.

Regnskap MCP let AI assistants keep the books in Fiken, with approval of every action, full traceability and undo. It was shut down once the accounting providers started shipping their own MCP servers.

Built by a pentester

An AI that can do things can also do the wrong things. That's why I put approval and limits on the server, and give the AI only the access it needs.

How we can work together

  • Fixed-price project

    You get the price in writing before anything starts, and a finished, tested result.

  • Consulting

    Hourly, in your codebase and alongside your team.

  • Operation and maintenance

    I run and maintain what I've built, so it keeps working.

  • Maintenance agreement

    A fixed agreement for updates, security fixes and small changes.

Questions and answers

Is our data sent to AI services?

We decide that per project, based on what the data is. If the solution handles personal data, we sign a data processing agreement.

What is an MCP server?

A standard way to give AI assistants such as Claude and Cursor access to a system. The server decides what the assistant may do, and that's where I put the limits.

Who owns the code?

We agree on that in the quote, for each project.

How fast will I hear back?

Within one working day.

Do you work with businesses outside Norway?

Yes. I'm in the same time zone as Stockholm and Berlin, and I take meetings in Norwegian or English.
