the tab you didn't want to open
You're writing something and you remember a thread you saved. To find it you open a new tab, go to xmark, search, read, and come back. It works. It is also four steps for one thought, and by the fourth you have lost the sentence you were writing.
The xmark Chrome extension is the same search and the same chat, in a popup on the toolbar. Click, ask, read, close.
what it does
- Search. Type what you remember, in your own words. Results are your bookmarks, each linking to the post on X.
- Chat. Ask a question and get an answer drawn from your bookmarks, with the posts it used listed under it. While the popup is open, follow-up questions stay in the same conversation.
- Sync now. A button in the footer pulls your newest bookmarks from X. If X is rate limiting, it tells you how long to wait.
- Usage. The footer shows how many bookmarks you have synced and where you stand on chats.
Your plan's limits apply in the extension exactly as they do on the site. It is another way in, not another product.
what it doesn't do
It does not read x.com, or any other page you visit. It asks Chrome for one permission beyond storage: to talk to api.xmark.dev. Your bookmarks still reach xmark the way they always have, through X's API after you connect your account, not by watching what you scroll past.
That is also why it does not save a post for you. Bookmark on X as usual, on your phone or anywhere else, then sync.
setting it up
- Install the extension from the Chrome Web Store.
- In xmark, open settings, then API, and create a key.
- Paste the key into the extension's settings tab and save.
The key is stored in that browser only and is sent only to xmark's API. Remove it in the extension, or revoke it in xmark's settings, and the extension is signed out.
