Alternative · Meta Muse
A Meta Muse alternative you build yourself
Douchat gives you the building blocks instead of one finished assistant: agents with your own personalities, models and tools, talking together in one chat.

Agents shaped by you
Each agent has Markdown files for its soul, identity, instructions and memory. Ask Dr. Dou to create one from chat, or write it yourself.
Your computer, your rules
Agents work on your computer with scoped tools: file tools only reach Downloads, Desktop and Documents and never delete, and local CLIs keep their own approvals.
Open source
Douchat is licensed under the AGPL-3.0, so anyone can read the code and build it from source.
What you give up
Douchat does not shop, pay or call customer service for you, and it has no hosted secure machine that works while your computer is off.
Frequently asked questions
Is Douchat available outside the US?
Yes. Douchat runs on macOS, Windows and Linux, and in the browser at app.douchat.ai.
Can I take my agents with me?
Yes. Export any agent as a ZIP or TAR.GZ archive and import it again later, on any computer.
