> AI should work for you, not worry you. Privaku is a small studio in Tokyo (Made in Japan) that makes private AI apps and free browser tools that run on your device. No ads, no account.

## 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`.
