Most “AI coding tools” are still two separate products pretending to be one. You have an editor, and then you have a chat panel or a terminal agent that doesn’t really live inside the same context.Cerin is the first free tool I’ve used that was designed the other way around.The agent and the editor share the same memory. The agent can edit files in the editor, run commands in your real shell, and see what you just typed by hand. You control how much autonomy it gets with a simple Plan → Act → Autopilot dial.
The Autopilot is the part that feels new. It can take a failing test, read the error, edit the code, re-run the suite, and continue without constant confirmation. Every step is visible and interruptible.It supports any major model provider or your own keys. Context stays intact when you switch.And the whole thing is free.You can download it at cerin.space. No credit card, no forced signup for the core features.
If you’ve been waiting for the agent and the editor to finally become one system, this is the first free version that actually delivers on that idea.
