Questions, answered

Yes. Privane runs Gemma 4 on your device with WebGPU. Chats and page content used for local AI stay on your machine — they are not sent to Privane cloud servers for inference.
Honestly: cloud models like ChatGPT are stronger at complex reasoning. Privane wins when privacy and browser context matter — your tabs, history, and notes never leave your device, and you pay once instead of a monthly cloud seat.
Chrome 113+ on a desktop with WebGPU support. Most machines from ~2018 onward work. The model is ~1.6GB and downloads once.
Free includes on-device Gemma 4 chat, page summarization, research mode, chat-with-page, and a sidebar on every site — with no signup, no API key, and no cloud token limits. It works offline after the model downloads. Pro adds Agent Mode, Memory Vault, Workspaces, Daily Journal, and the Floating Action Bar.
Pro unlocks Agent Mode (tabs & history), Memory Vault, Workspace Intelligence, Daily Journal, and the Floating Action Bar. That’s the “browser brain” layer.
After payment you get a PRIV-XXXX license key by email and on the success page. Paste it in extension Settings → Validate.

Private AI that lives where you already work — your browser.
