Your bookmarks, kept for good
Tags, privacy, read-later, and full-text search — plus archiving that survives link rot and AI you can actually ask. Bring your browser bookmarks or your Pinboard library over — free, in one click.
The modern bookmark manager
Pinboard should have been.
Full-text search across everything you save, full-page archives that beat link rot, distraction-free reader, and private AI you can query. 100% portable with zero lock-in.
14-day free trial · No credit card required · Export anytime · No ads, no third-party trackers
Three steps to your library
Same golden path as the app — sign up, save, find anything.
Start your free trial
Sign up with email or Google — then land on your bookmarks list.
Save from anywhere
Paste a URL, use the bookmarklet, forward email, or import your Pinboard export.
Tag, search, focus
Filter read-later, star favorites, run full-text search, and let Focus today rank what to read next.
Everything Pinboard did —
plus what it skipped.
Permanent S3 HTML archiving, sub-50ms search, 2-way continuous Pinboard mirror, and clean reading with highlights.
Full-page archives that outlive the original
Pew Research found that 38% of webpages from 2013 were gone a decade later. Cowpin saves the readable text of every page you bookmark, and with AI & Archive it also keeps a full-page copy (styles and images included) in our own storage.

Pinboard sync & API
Run Cowpin alongside Pinboard. Connect your account and new Pinboard saves come in once a week; the optional mirror pushes your Cowpin changes back, and never deletes anything there. Existing Pinboard apps work with your Cowpin API token.
✓ 1,420 bookmarks imported · nothing deleted on Pinboard
Apple Health for Bookmarks
Track 12-week reading volume, revisit rates, topic breakdowns, and dead links. Turn your link stash into an active, high-yield knowledge system.
Distraction-Free Reader & 1-Click Markdown Export
Read cleanly without ads or pop-ups. Select any sentence to create a highlight with your own notes, then export all of them as one Obsidian-friendly Markdown file.
"The best bookmark managers don't just store URLs; they preserve the exact thoughts and highlights that inspired you in the first place."
Save From Everywhere
Save without opening the dashboard. Use the official Chrome & Firefox extensions, the share sheet (an iPhone Shortcut, or the Android home-screen app), save-by-email forwarding, the bookmarklet — or follow RSS feeds and let new posts save themselves.
Ask Your Library (AI)
Query your bookmarks naturally in plain English. Cowpin's semantic RAG answers questions citing your exact saved articles with source links.
"What did I save regarding Postgres connection pooling?"
Native Desktop Clients &
Terminal CLI for Power Users
Whether you prefer a lightweight native desktop menu app, an official browser extension, or an automation-ready terminal CLI, Cowpin fits right into your workflow.

A native, lightning-fast WebKit desktop client built for macOS Sequoia & Sonoma. Runs natively on Apple Silicon and Intel in a download under 1 MB — zero Electron memory bloat. Press ⌥⌘B in any browser to save the page you're reading, with tags, without switching windows.

Tested every day on real browsers and real phones
Your bookmarks should outlive any one app. So Cowpin is tested the way you use it, on the live site, every day.
Every day, in real browsers
Chrome, Firefox and Safari's engine sign in, save, search and use the extension and bookmarklet on the live site.
Every week, on real Android phones
A Pixel and a Galaxy sign in, save, share from another app, search and open notes.
Every release, checked before you see it
A new version goes live only after automated checks pass on it. A failing build never reaches you.
Every minute, watched
The site is checked every minute and the database every 15 minutes, and a sign-in email to an outside inbox is checked every day. An alert goes out as soon as something breaks.
