Updated
Microsoft 365 Copilot edits documents from inside Word, Excel, and PowerPoint. It comes with a Microsoft 365 subscription. Mimzie is a free desktop app that opens the same files with the agent you choose. It runs Claude, ChatGPT, Gemini, and Grok on your computer, on the AI plan you already pay for, and by default each change waits for you to accept or reject it.

Why people choose Mimzie over Microsoft Copilot
You choose the agent
Copilot is one assistant. Microsoft's Excel FAQ says it "supports Claude models from Anthropic and GPT models from OpenAI", and that switching between them needs Microsoft 365 Premium or a commercial Copilot subscription. In Mimzie you pick Claude, ChatGPT, Gemini, or Grok for each chat, and you can switch in the middle of a project. If you already pay for one of them, you get the same agent you use everywhere else.
One request can cover the whole project
Copilot works in the file you have open. A Mimzie project is a folder, and an agent can read the contract, update the spreadsheet, and build the deck from both in one request. Mimzie's bots go further. A lead bot splits a job between a research bot, a numbers bot, and a slides bot, and brings the results back in one reply.
You review changes before they land
In Excel, Copilot changes the workbook directly. Microsoft's FAQ says Copilot "edits your workbook directly based on your requests", and "If you need to revert your changes, you can undo changes or view prior versions."
Mimzie shows each change as a tracked edit. 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.
You do not need a Microsoft 365 subscription
Mimzie opens and edits .docx, .xlsx, and .pptx files in its own editors. The files stay in their original formats, so anyone with Office can open them.
Where Microsoft Copilot is the better choice
- You live in Word, Excel, and PowerPoint and want help without leaving them.
- Your company already pays for Copilot and manages it through Microsoft 365.
- Your files live in SharePoint or OneDrive and several people edit them at once.
- You depend on Office features that other editors do not have, such as macros.
Mimzie vs Microsoft Copilot: common questions
Is Mimzie a Microsoft Copilot alternative?
Yes, for getting AI to write and edit Word, Excel, and PowerPoint files. Mimzie is a separate app, so it does not replace Copilot's help inside Outlook or Teams.
Which is cheaper?
Mimzie is free and uses the Claude, ChatGPT, Google, or Grok plan you already have. Copilot needs Microsoft 365. Personal costs $9.99 a month, Family $12.99, and Premium $19.99. On Family, Microsoft says Copilot in the Office apps is "available only to the subscription owner." For work accounts, Microsoft 365 Copilot is $30 per user a month, paid yearly.
What if I have no AI plan?
Mimzie has its own agent with free models.
