Running AI Locally in Modern Browsers
When building tools for privacy-minded people, doing the work on the client keeps their data off the network.
Built-in browser models such as Gemini Nano run on the device's own hardware, so text can be summarized without being sent to a cloud server.

Everything you need to keep and recall
Each website gets its own notebook, automatically.
One-click saving & tags
Select text anywhere and click Save. Add tags as you save, with suggestions from the tags you already use.
Highlights that stay
Saved text shows highlighted when you return to the page, and you can jump straight to it from your library.
A notebook for the web
Every website forms its own notebook. Search, tag, favourite and sort, and switch between Cards, List and One-after-another views.
Keeps code & formatting
Headings, bullet lists and code blocks keep their layout. Code shows in a dark box with a one-click copy button.
Private AI summaries
Turn a page or your highlights into key points with Chrome's built-in Gemini Nano, which runs on your device. No API keys.
Export anywhere
Take your notes out as PDF, Word, plain text or JSON. Restore a JSON backup any time, with no lock-in.
Chrome's built-in AI.
Nothing sent to the cloud.
Okapi has no servers and no accounts. Your highlights are stored in your browser and never leave your computer, and that includes AI summaries.
Runs on your device completely free
Summaries use the model built into Chrome. No API keys and no usage costs.
No accounts, no tracking
No sign-up, no analytics, no ads. Read the full privacy policy.
