What is keepthis.site and what does it do?

keepthis.site is a personal bookmark manager that saves links, full-text search, and real page screenshots, with end-to-end encrypted sync between your own devices. It is aimed at people who want a private, search-first library of things they intend to revisit rather than a social or algorithmic feed. It runs on macOS 12+ and Android 8+ (arm64), and the browser extension is currently available for Firefox.

What you can save and how you find it

You can save articles, docs, videos, and tools — anything you want to come back to. There are no folders to maintain; the product's stated model is that search does the organizing.

• Instant search: Find items in milliseconds by title, by note, or by anything you wrote about them.
• Real previews: Each saved link gets an actual screenshot of the page rather than a generic thumbnail, so you can scan your library visually.
• Offline use: Pins live on your device, so the app keeps working on a plane or a flaky connection.

How the encryption and sync work

Your data is encrypted on your device with a passphrase only you know, before it leaves the device. It then syncs peer-to-peer between your own devices — there is no account and no server in between to read it. The practical implication is that the passphrase is the key to your library: the service cannot recover your data for you, and you should treat the passphrase as something you must not lose.

Saving from the browser

The Firefox extension saves the active tab — URL, title, your tags, and your notes — straight to the desktop app with one click. There is no login or sign-up, and activeTab is the only page permission it requests. Two conditions matter:

1. The Mac app must be running in the background to receive saves.
2. The extension pairs with keepthis.site for Mac specifically.

A Chrome Web Store version is listed as coming soon.

Platform and version details

Is it a fit for you?

It suits you if you want a private, encrypted, search-driven bookmark library across a Mac and an Android device, and you are comfortable managing a passphrase yourself. It is a weaker fit if you need a Chrome extension today, use Windows or iOS, or want folder-based organization and shared or collaborative bookmarking — none of those are described in the product materials.
