What is WebLLM and how does it work for private AI?

WebLLM runs LLMs in-browser via WebGPU and TVM.js. Downloads model shards once, caches 'em. Chats locally — no servers.

Can I build an offline mental health tracker with React?

Yep. Follow the guide: Hook up useWebLLM, prompt for CBT analysis, store in IndexedDB. Offline, private, cheap.

Safer than cloud, sure. But LLMs err, browsers vuln. Encrypt storage, don't bet your life on it.

Your daily journal, analyzed by AI right in Chrome, zero cloud snooping. Dream for the paranoid — or just smart folks tired of data vampires.
