Mentat

Mentat is an AI coding assistant designed to work with your entire codebase, not just individual files. Named after the human computers in Frank Herbert's Dune, Mentat understands project-level context and can make coordinated changes across multiple files — a capability that distinguishes it from simpler AI coding tools.

Mentat's approach to codebase understanding is its key differentiator. Instead of treating each file as an isolated context, Mentat builds a model of your project's architecture — understanding how files relate to each other, how functions are called across modules, and how changes in one file affect others. This holistic understanding enables refactoring and feature implementation that spans the entire project.

The tool runs in the terminal and works with any programming language and project structure. Its clean interface and focused feature set make it approachable for developers who want AI coding assistance without the complexity of more feature-heavy alternatives.
