About DevTools AI
A small, focused toolkit — not a platform.
Why it exists
Most AI coding assistants live inside an editor or a chat window that doesn’t fit every task. DevTools AI is the opposite: ten single-purpose tools — explain, review, optimize, generate — each with exactly the input and output it needs, and nothing else in the way.
It’s built on OpenRouter so it isn’t tied to one model provider, and it’s open source so you can read exactly what happens to your code before you paste anything into it.
How it handles your data
There are no user accounts and no database. Your OpenRouter API key lives in server-side environment variables and is never sent to the browser. Requests are proxied straight through to OpenRouter and are not logged or stored by this app. Your model, temperature, and max-token preferences are saved only in your browser’s local storage.
