Recognize content across domains
A site can contain multiple domains or URL prefixes. When it moves, matching paths can retain a stable content identity.
Local-first · Chrome & Edge
URLs change. What you read should not.
PathMark is more than another bookmark folder. It keeps pages, notes, reading states, and content identity together—so even when a website moves domains, you still know what you have read.

Built for people who actually come back to read
From quick capture to rediscovery, PathMark preserves more than a link. It keeps the context your future self needs.
Reading states that stay clear
Unread, reading, read, and archived stay distinct. The toolbar icon changes color to reflect the current page.
Save the reason, not just the URL
Capture a title, personal note, tags, and collection so you remember why it mattered and what to look for.
Match existing sites automatically
The popup recognizes the current domain, selects a known site, or helps create a new site and its first endpoint.
A complete local library
Search and filter by state, site, collection, tag, or date. Organize in bulk, migrate identity, and choose where to open an item.
Your data stays yours
Business data lives locally in the browser. Export complete JSON backups and merge or restore them transactionally.
Build a reading memory in three steps
Capture stays lightweight. Deeper organization waits until you actually need it.
Open PathMark on any page
Use the toolbar icon or shortcut to see immediately whether the page is saved and what its reading state is.
Add context and save
Record a note, tags, and collection. The site and endpoint are suggested automatically from the current URL.
Read, migrate, rediscover
Even after a domain changes, the stable site identity helps recognize and open the same resource again.
Start with the next page you mean to read later.
