Private beta

Dossier

Pro free during the beta

PowerPoint and Word, for your AI agent.

It writes the decks and docs. You keep the last word.

Private beta. Invites go out by hand, a few at a time.

01Slides

Slides that don't look AI-made

Your agent builds slides from typed blocks: stats, panels, tables, annotated screenshots. It can't invent a layout or break the design, and every slide is checked in a real browser before you see it.

02Writing

Markdown docs made beautiful

Write plain Markdown. It comes out themed, with a title card, contents built from the headings, and the same look as the decks.

04AI agents

Your LLM writes, you approve

Claude, ChatGPT and other LLMs work over MCP or a command line, through the same API as the editor. The server refuses anything that doesn't fit, and every save is a version you can undo.

05Every night

Nothing gets lost

Every deck, doc and image is copied each night, checked, and sent to a second cloud. Once a month a restore drill runs, so recovery is tested before you ever need it.

06Private beta

Bring your own agent

Dossier works with the AI you already use. Beta users get Pro free while the beta runs, and half price for good after it.

I build tools for teams and their AI agents. Dossier and Bureau started as my own. I build the same kind for other teams, shaped around their work.
