Highlight directly on the page

Highlight Notes Sync
Turn web reading into a structured note system: highlight passages, attach notes and tags, manage everything by source article, then export or sync when you need it.
Local first
Markdown export
WebDAV optional
Notion optional
Capture the exact sentence that matters, then keep the context, source, tags, and note attached.
Built for readers who keep receipts.
Highlights stay useful because they retain source, context, notes, tags, and export paths instead of becoming isolated snippets.
02
Add notes and tags in flow
Attach quick thoughts, labels, and reading context while the passage is still fresh, then refine them later from the manager.
03
Manage by source article
Review saved highlights in a dedicated manager with article grouping, search, filters, starring, editing, deletion, and source links.
04
Export without lock-in
Download article-grouped Markdown files or a JSON archive when you want to move notes into another writing or knowledge workflow.
A cleaner loop from reading to retrieval.
The extension is designed around the recurring steps of serious web reading.
Keep the sentence, not the whole tab.
Save the part you actually need and preserve the page title and URL with it.
Turn a quote into usable memory.
Add notes and tags so the highlight can be searched and understood later.
Move highlights into your own system.
Export Markdown or JSON, or sync to destinations that you configure yourself.
Sync is optional, explicit, and user configured.
Highlight Notes Sync works locally by default. When you want a cross-device or knowledge-base workflow, connect your own WebDAV endpoint or Notion database from the options page.
- WebDAV stores a JSON snapshot at your configured path.
- Notion writes one row per source article with highlights in the page body.
- Manual and scheduled sync keep edits and deletions moving through the queue.

Make web research easier to review, export, and reuse.
