Built for the whole reading lifecycle.

Notebook Highlighter is not just a text marker. It connects highlighting, reader mode, search, export, bookmarks, reminders, and optional AI into one reading workspace inside Chrome.

Notebook Highlighter search results across saved highlights from multiple pages — Search your whole library

Notebook Highlighter reader mode showing a clean reading layout — Reader mode clears clutter

Notebook Highlighter export options for markdown PDF Obsidian and Notion — Export into your workflow

Privacy model

Your reading archive belongs to you.

Highlights, notes, bookmarks, reader copies, reminders, and settings stay in local browser storage by default. Data leaves the browser only when the user explicitly turns on a feature such as AI summary, custom sync, or a third-party export integration.

No NHR Soft account

The extension is designed to work without sign-up, developer cloud storage, or analytics.

Bring your own AI key

Optional AI summary and chat use the endpoint and key the user configures, not a hidden developer service.

Local-first exports

Markdown, HTML, PDF, and local share flows are generated on-device unless the user chooses a remote integration.

Broad access explained

Website access exists so the extension can capture a user-selected highlight and restore annotations on the same page later.

Keep your highlights, notes, and reading exports in one offline-first workspace.

Notebook Highlighter is built for people who want to mark up web pages and PDFs, organize what they found, and move that material into the tools they already use.
