The Vault
A CBT mirror that runs 100% on-device — nothing stored
The Vault is a no-coddle CBT "Socratic mirror" in a single HTML file. A small LLM runs entirely on your device (WebGPU, CPU fallback), keeps nothing, sends nothing — no server, no account, no analytics. You type what's going on; it reflects it back, names the distortion, offers a reframe. Built for people who can't or won't reach mental healthcare. Open source (GPL v3).
Maker here. I build sound for a living; I built this across a few late nights because America's mental healthcare is hard to reach and harder to afford, and a sounding board that keeps NOTHING felt like the honest version of this idea. One file, on-device model, PURGE button, done. The design call people argue with: the crisis net is narrow on purpose — imminent danger gets a human voice and real numbers; dark thoughts get listened to, not lockout letters. The full reasoning is in the README. It's GPL — if you can carry it somewhere I can't (another language is the big one), it's yours.
