We wanted an AI coding workspace we could use on sensitive projects without routing data through someone else's cloud. So we built one that runs entirely in the browser — local GPU inference, real file access, no backend.
This started as an internal tool. We needed an AI assistant for work involving code and documents we couldn't put into third-party APIs. The constraint was simple: nothing leaves the machine.
ZeroKeep runs entirely in the browser. Models run on the user's GPU via WebGPU. Files are accessed through the browser's native File System API. There's no server, no account, and no database we operate.
A few things we found useful in practice:
* The diff review step before any file write — the AI proposes, you approve
* Being able to define custom JS tools the agent can call
* Model caching so you're not re-downloading on every session
It's not trying to compete with Cursor or Claude Code. It's for situations where those tools aren't an option.
Works in Chrome and Edge. Requires WebGPU support.
