Import Your X (Twitter) Bookmarks Into Cowpin

Cowpin does not sync X bookmarks live from your account — there is no official “pull my bookmarks daily” API for strangers. What we do ship is an import path for the files X gives you in a data export, plus paste-in for the same formats.

That matches how we talked about BookmarkBrain vs Cowpin: Reddit and X archives in, not a proprietary X bookmark API.

Where to import

Settings → Account → Bookmarks → Import

Scroll to Twitter / X. Paste the file contents into the text area and click import. You can also drop a file into the general import zone — if it looks like an X archive, Cowpin routes it to the same parser.

Supported export shapes

The parser (twitter-import.ts) accepts:

Export file (typical)Format
bookmark.js / bookmarks.jswindow.YTD.bookmark.part0 = [ … ]
like.js / likes.jswindow.YTD.like.part0 = [ … ]
tweet.js / tweets.jswindow.YTD.tweets.part0 = [ … ]
Plain JSONArrays/objects with tweet ids, expanded_url, full_text, etc.

Cowpin walks tweet entities and expanded URLs, keeps normal http(s) links, and tags imports with twitter (plus your optional extra tag). Pure twitter.com/i/web/status/… rows without an external URL are skipped — there is nothing to archive as a page.

What you get after import

  • Bookmarks in your library like any other save — archive, tags, search, export.
  • No automatic re-sync when you bookmark on X again; re-export and import deltas when you need them (same as most migration workflows).

Honest limits

  • Not a Chrome extension that reads x.com’s bookmark UI in real time.
  • Media-only or quote-tweet rows may import as the best-effort URL we can extract.
  • Very large exports: import runs server-side; watch the success count in Settings.

Request your X data

Use X’s Download your data flow (account settings). Unzip and open the data folder — paste bookmark.js (or the JSON you care about) into Cowpin.
