What is keepthis.site?
keepthis.site is a personal bookmark manager built around privacy. You save links—articles, docs, videos, tools—and the app captures a screenshot of each page, then lets you search your whole library by title, note, tag or anything else you wrote. There are no folders to maintain; search is the organizing principle. Its distinguishing feature is end-to-end encrypted, peer-to-peer sync: data is encrypted on your device with a passphrase only you know and syncs directly between your own devices, with no account and no server holding readable data. It runs as a Mac app (macOS 12+) and an Android app (Android 8+, arm64), works offline, and has a Firefox browser extension that saves the current tab with one click (Chrome is listed as coming soon). The Mac app must be running in the background to receive extension saves.
Who it suits
- Privacy-focused individuals who want a bookmark library without a cloud account or a company able to read their saves.
- Researchers and heavy readers who accumulate links and prefer instant full-text search over manual folder structures.
- Visual browsers who like scanning screenshots to recognize pages rather than reading a list of titles.
Trade-offs to weigh
- Device ecosystem: Mac plus Android is an unusual pairing; iPhone, Windows and Linux users are not addressed on the page.
- Sync model: peer-to-peer sync means your devices must be able to reach each other, and losing your passphrase may mean losing access—there is no server-side recovery described.
- Browser support: Firefox only for now, so Chrome-dependent workflows wait.
As a next step, if you use a Mac and Firefox, install the Mac app and extension and save a handful of links to test whether screenshot-plus-search matches how you actually retrieve things. If you rely on iPhone or Windows, compare against a cross-platform alternative such as Raindrop.io before committing.
How does keepthis.site keep my bookmarks private with end-to-end encryption?
keepthis.site encrypts your bookmarks on your own device using a passphrase only you know, then syncs the encrypted data directly between your devices. Because there is no server in the middle, no one—including the service—can read your library. The site states there are no accounts, so there is no login profile tying your saves to an identity.
What that means in practice
- Encryption happens before sync. Data is encrypted on your device before it leaves it, so what travels between devices is already unreadable ciphertext.
- Peer-to-peer sync. Your devices exchange data directly rather than through a central store the operator could inspect.
- Passphrase-based access. Your passphrase is the key; losing it likely means losing access to the encrypted library, so keep it somewhere safe.
- Local-first storage. Pins live on your device and work offline, so your library remains usable without a connection.
Trade-offs to weigh
| Benefit | Trade-off |
|---|---|
| No server can read your data | No account recovery if you forget the passphrase |
| Syncs only between your own devices | Adding a new device requires the passphrase and a paired setup |
| Works offline | Devices must be online at some point to sync changes |
| No sign-up | You manage your own key and backups |
A concrete scenario
Suppose you save a recipe on your phone while commuting. The bookmark is encrypted on the phone, then synced directly to your Mac when both are online. If someone intercepted the transfer, they would see only ciphertext. If you later lose the phone, your Mac still holds the library—but only your passphrase unlocks it on a replacement device.
Next step: before relying on it, test the recovery path. Save a few links, note your passphrase, then try opening the library on a second device. That confirms your setup works and reminds you where your passphrase is stored.
Can I sync my saved links across my Mac and Android phone without a server?
Yes. keepthis.site is built for exactly that setup: saves are encrypted on your device with a passphrase only you hold, and sync happens peer-to-peer between your own devices rather than through a company server. The site's own framing is that there is "no server to read it, and neither can we," and that no account is needed. A Mac plus an Android phone is supported — the site lists a Mac download and an Android download (macOS 12+, Android 8+ arm64).
What that means in practice
- Encryption before sync: data is locked on the device first, so the sync channel carries ciphertext. This is the main reason a serverless design is credible here.
- Your passphrase is the key: if you lose it, there is no account recovery to fall back on. Store it somewhere durable before you rely on this.
- Offline-first: pins live locally, so saving and searching work on a plane or a weak connection; syncing catches up later.
One friction point to plan around
The browser extension (Firefox, with Chrome "coming soon") saves the current tab to the desktop app, which must be running in the background to receive saves. So quick capture from a browser is a Mac-side workflow; on Android you'd save from the app itself. Also note the site describes no folders — retrieval is by full-text search and screenshots, which suits people who save a lot and search rather than tidy.
Decide by your tolerance for irreversibility
Peer-to-peer with no server is a good fit if you value privacy over convenience and are comfortable managing your own passphrase and keeping both devices available to sync. If you want web access from a borrowed machine, shared libraries, or password reset, a hosted service is the easier trade — for example Pinboard for plain hosted bookmarks or Raindrop.io for cross-platform collections. Next step: install on both devices, save one test link on each, and confirm it appears on the other before moving your existing library over.
How do I save a link from my browser to keepthis.site?
Install the keepthis.site browser extension and click its toolbar button while you're on the page you want to keep. That single click sends the current tab's URL, title, and any tags or notes you've added straight to the keepthis.site desktop app on your Mac.
The extension is currently available for Firefox. A Chrome Web Store version is listed as coming soon, so Firefox is the practical route today.
What needs to be in place first
- The Mac app must be installed and running in the background. It's the receiving end of every save, so if it's closed, the click has nowhere to land.
- The extension only needs the
activeTabpermission. It reads the current tab when you click, and no login or sign-up is involved. - Your saves are encrypted on your device with a passphrase only you know, then synced directly between your own devices rather than through a server.
A typical workflow
Say you're reading a long article and want it for later. Click the extension button, add a short note like "reference for the Q3 write-up," and move on. Later, open the Mac app and search by that note or by the title — the site says search returns results in milliseconds and works across titles, notes, and anything else you wrote. Each saved link also gets a real screenshot of the page, so you can scan your library visually instead of reading a list of URLs.
Practical points to weigh
- No folders to maintain. The design assumes search replaces organization, which suits people who save often and hate filing. If you think in hierarchies, this will feel loose.
- Offline-first. Pins live on your device, so saving and searching work on a plane or a flaky connection.
- Passphrase discipline matters. Because encryption happens before data leaves your device and there's no server holding a copy, losing the passphrase is a real risk to your library.
- Platform coverage is narrow for now. Mac plus Android, with Firefox as the only browser extension. If you browse mainly in Chrome or work on Windows, this isn't a fit yet.
Next step
Install the Firefox extension, confirm the Mac app is running, and save one page with a note attached. Then search for that note in the app — if it surfaces immediately, the loop is working and you can save freely from there.
How does full-text search work across titles, notes, and saved links?
Full-text search in keepthis.site is described as instant lookup across everything you've saved, matching on title, on note text, and on "anything you wrote about it" — so the words you attach to a link are as searchable as the link's own title. The page presents it as the replacement for folder structures: rather than filing saves into categories, you pin them and rely on search to retrieve them later.
What the page says about scope
- Titles: the saved page title is indexed and searchable.
- Notes: your own annotations are searchable, which is what makes a "why I saved this" note worth writing.
- Tags: the extension saves "your tags, your notes" alongside URL and title, so tags are captured at save time; the page lists title, note and "anything you wrote" as search targets rather than spelling out tag matching separately.
- Screenshots: every save gets a real page screenshot, which the page frames as visual scanning of your library — a separate way to find things than typing a query.
What the page does not specify
The site doesn't describe the matching method (exact phrase vs. partial word), ranking of results, handling of typos, or whether the contents of saved pages are indexed versus only the metadata you attach. If searching inside article bodies matters to you, treat that as unconfirmed and test it before committing your library.
A practical scenario
Suppose you save a long read on encryption and add the note "passphrase recovery — compare with keychain approach." Months later you remember the idea, not the headline. Searching "keychain" or "passphrase" should surface it through the note, while searching a remembered phrase from the headline works through the title. That is the intended workflow: lean on your notes for recall, and use screenshots when you recognise a page visually but can't name it.
Decision criterion
Search quality depends on what you write. If you save links with a one-line note about why, title-plus-note search covers most recall needs. If you expect to search the full body text of saved articles, ask the developer directly or try a handful of saves with distinctive in-page phrases before relying on it.
Where it fits
The search runs over a local, encrypted library — pins live on your device and sync peer-to-peer, with no account and no server holding readable data. So search speed and availability track your own machine and synced devices rather than a cloud index. For comparison with cloud-based bookmark tools that index page content server-side, see Pinboard and Raindrop.io; the trade-off is local privacy and offline access versus server-side indexing depth.
What happens to my bookmarks when I'm offline or on a bad connection?
Your saved bookmarks stay available offline because they live on your device. keepthis.site describes pins as stored locally, so you can open the app and save links on a plane or a flaky connection, and everything keeps working. New saves sync to your other devices once a connection returns.
What the page says happens
- Saving offline: The desktop app and its browser extension save the URL, title, tags and notes to the app on your machine; no login or server round-trip is involved.
- Reading offline: Your library is on your device, so search and screenshots of already-saved pages remain usable without a connection.
- Syncing later: Data is encrypted on your device with your passphrase and syncs peer-to-peer between your own devices, with no server in between. Sync therefore needs your devices to reach each other; it is not a cloud copy waiting on a server.
- Extension caveat: The Firefox extension sends saves to the Mac app, which has to be running in the background to receive them. If the app isn't running, a one-click save may not land until it is.
Practical scenario
Suppose you're on a train with intermittent signal and want to keep three articles for later. You save them from the browser extension or the app; they're written locally with your tags and notes. When you're back on Wi-Fi with your other device nearby, the encrypted changes sync across. If a save doesn't appear on the second device, check that both apps are running and can see each other.
Decision criterion
Offline-first saving suits people who save in bursts on the move and dislike losing a link to a failed connection. If you expect sync to work through a central cloud service when your devices are apart, peer-to-peer syncing is the trade-off to weigh before committing.
