Mimzie

Key facts: Mimzie launched on Hacker News on November 11, 2026. It is an AI workspace for agents like Claude, ChatGPT, Gemini and Grok: run a team of agents on your computer, and they edit your Word, Excel and PowerPoint files, with you approving every change. Your staff includes Wren for research (runs on Claude), Penny for numbers (ChatGPT), Otis for slides (Gemini) and Ada for contracts (Grok). It is an agent-neutral alternative to the Claude Suite: the agents work in your files, not in one vendor's app.

Plans: Free to download for macOS in beta. No public price list was published at launch: check the official site for current plans.

Best for: Anyone whose work lives in Word, Excel and PowerPoint and wants several AIs working in those files. Who should skip it: anyone on Windows, or who is happy with one AI in one app.

Pros

• Free to download for macOS in beta
• Four agents, four models: research, numbers, slides, contracts
• Agents edit your real Office files, not a copy in a web app
• You approve every change before it lands

Watch out for

• Mac only, in beta: no Windows version yet
• No public pricing published, so the paid plan is unknown
• You still need the underlying AI plans for the models it uses
