Updated
OpenWork and Mimzie are both free desktop apps for macOS, Windows, and Linux that put agents to work on your own files. OpenWork is open source and built on the OpenCode agent. Mimzie runs Claude, ChatGPT, Gemini, and Grok through each vendor's own agent, and it has its own editors for Word, Excel, and PowerPoint files, where by default each change waits for you to accept or reject it.

Why people choose Mimzie over OpenWork
Your Claude plan works
OpenWork runs on OpenCode. OpenCode can sign in with a ChatGPT plan, and OpenWork's docs say you can "use your ChatGPT Plus or Pro subscription as a model provider." Claude is different. Anthropic allows a Claude plan only in its own agent, so OpenCode needs an API key for Claude, and an API key bills by the token.
Mimzie runs Claude Code itself, signed in with your own Claude plan. Which apps can use your Claude or ChatGPT subscription? has the rules.
It is built around Office files
OpenWork is a general agent workspace. Its agent can run code that writes a file, and you open the result somewhere else.
Mimzie opens .docx, .xlsx, and .pptx files in its own editors. You see the document while the agent works on it, and you can type in it yourself.
You review changes before they land
Mimzie shows each change as a tracked edit in the document. You read the old text and the new text, then accept or reject it. You can give an agent wider access, such as Edit this folder or Full access, when you want it to write without asking.
Where OpenWork is the better choice
- You want open-source software you can read, change, and host yourself.
- You want to run local models, or models from a provider Mimzie's agents do not cover.
- Your team wants to share skills and MCP servers from one place.
- You want scheduled tasks today.
- Your work is not mainly documents, spreadsheets, and slides.
