Before every coding assistant wanted to know your whole repository, MutableAI made the repository write its own field guide. The product is gone, but its sharpest idea now has a second life inside Google.

The coding assistant that began by rescuing snippets now conducts whole rooms of rival models. It is fast, useful, sprawling - and worth trying with both hands on the wheel.
Cline is an open-source, autonomous AI coding agent that runs inside VS Code and other editors. It reads a codebase, plans changes, edits files across a project, runs terminal commands, and drives a browser - asking for the developer's approval at each step. Built to be transparent and model-agnostic, it lets teams bring their own API keys or run local models, and has grown into one of the most-installed AI coding tools with a Fortune 500 enterprise offering, Cline Teams.
