Sped up for the demo. SyncX syncs in the background on your schedule — every 12 hours by default.
No new habit
No links to share. Old saves come along too.
Read-later and note apps need every item shared to them by hand, so years of saves never make it in. SyncX reads the likes and saves you already make on each platform, so nothing about your routine changes.

Set it up once
1Sign in once
SyncX opens a dedicated window in Chrome, Edge, Brave or Chromium on your computer. Your everyday browser profile is never touched.
2Pick what to collect
Turn saves, likes and favorites on one by one, each on its own schedule — every 12 hours by default.
3Then forget about it
SyncX runs in the background and backfills older saves in batches. Each list shows its last and next run, and an expired login is flagged once.
Platforms
Three platforms, one library.
Sign in with your own accounts and choose what to collect. Everything lands in the same library, to search and browse together.

Never lost
Gone from the platform. Still in your library.
Posts get deleted, videos taken down, accounts closed — and the save turns into a dead link. SyncX keeps the text, author, original link and images on your computer, so the copy stays readable after the original goes away.
- Text, author, publish and save dates
- Images saved locally, videos optional
- Opens offline
- Stays until you delete it
SyncX can only keep what it has synced, so start early. Bilibili videos are kept as links, not video files.

Yours alone
Your library lives on your computer, not on our servers.
SyncX has no cloud account and stores none of your data. It is an app on your computer, and your logins and saves stay there.
Your computer
SyncX appruns in the backgroundNo library upload, no cloud account
No cloud account
Records live in a local SQLite database and media are ordinary files. Back them up, move them, or export JSON and CSV any time.
Your browser stays yours
You sign in through a SyncX-only profile of Chrome, Edge, Brave or Chromium. Your everyday cookies are never read.
Logins stay local
Credentials are kept in native storage — never in logs, exports or on any SyncX server.
Statistics are opt-in
Anonymous usage statistics stay off until you agree, and never include accounts, content or searches.
Questions
Do I have to share links into SyncX one by one?
No. Keep liking and saving on X, Xiaohongshu or Bilibili as usual. SyncX checks on the schedule you set — every 12 hours by default — and picks up what is new.
Can it bring in my older saves?
Yes. After you connect, SyncX works back through your older saves and likes in batches, and picks up where it left off if a run is interrupted.
If a post is deleted, can I still see it?
Yes, if SyncX synced it before it was removed. The text, author, link and any saved images or videos stay in your local library until you delete them. Bilibili videos are kept as links, not video files.
Can I export X bookmarks or Xiaohongshu saves?
Yes. Any filtered library view can be exported as JSON or CSV, and saved images and videos are ordinary files you can back up.
Does SyncX upload my library?
No. Your library, media and platform logins stay on your computer, and there is no SyncX cloud account. Cloudflare serves this website and the installers, not your data.
Will my account get restricted?
SyncX uses your own login in a real local browser and reads your own saves at a modest pace, much like browsing them yourself. Platforms change their rules, so no tool can guarantee they never ask for verification; when they do, SyncX stops and tells you instead of retrying over and over.
Is SyncX free?
Yes. SyncX is currently a free public beta.
Which computers does it run on?
The public beta runs on Apple silicon Macs with macOS 13.3 or later. Windows and Linux versions are in preparation.
Why install from Terminal?
The beta is not Apple-notarized yet, so macOS would block a downloaded installer until you approve it in System Settings. The install command checks the file’s SHA-256 and signature, then removes the quarantine flag only from SyncX.app — Gatekeeper stays on. After that, updates take one click inside SyncX.
Like and save as usual. SyncX does the rest.
Free public beta. Your library never leaves your computer.
