# What is Mentat?

Mentat is an open-source CLI coding agent that can edit multiple files simultaneously from your terminal. Unlike chat tools that only suggest code, Mentat actually makes the edits, understanding the broader context of your project.

Who is it for? Developers and teams who want to delegate multi-step coding tasks to an autonomous agent.
