# PRIVAKU

> AI should work for you, not worry you. PRIVAKU is an on-device, offline LLM initiative to bring AI to the masses, without heavy token costs or privacy risks. It makes private AI apps and free browser tools that run on your device. No ads.

## Apps

Third-party AI apps you connect (like ChatGPT) are not end-to-end encrypted.

## Using the tools as an agent

There is no server API; tools run client-side in a browser the agent controls.
- Docs: https://privaku.com/tools/agents/
- Manifest: https://privaku.com/tools/agents.json
- Invoke: `window.privakuTools.run(tool, fileOrFiles, options)` on any /tools/ page; `window.privakuTools.inspect(file)` returns metadata groups.
- URL params preset options, e.g. `?remove=gps,xmp`, `?lang=jpn`, `?maxKB=200`, `?blurFaces=true`.
