x-pro.club vs ZeroMark
ZeroMark is an inbox for bookmarks: it summarizes what you saved and can answer questions with citations. x-pro.club does not upload your bookmark library. It filters the timeline and hosts public reviews.
Comparison
| Item | ZeroMark | x-pro.club |
|---|---|---|
| What it does | A web app. It summarizes each save, turns them into a queue, and adds cited chat, a topic map, and export to Notion or Obsidian. | A browser extension plus a public review site. It does not read your whole bookmark library, and it has no bookmark podcast or cited chat. |
| Price | Free reads the latest 50 saves, no card. The whole library and hourly sync are $4.99/month or $39/year. Tellurave LLC operates it; Stripe takes payment. | The extension and public reviews are free to use today. The pricing page lists Pro at ¥35/month ($5/month); checkout is not open yet. |
| Where data lives | Bookmarks are synced to their servers so they can be summarized. The X connection is read-only OAuth: it cannot post, follow, message, or delete bookmarks. They say bookmarks are not used to train foundation models; a third-party AI API writes the summaries. | Bookmarks, filter rules, and workspaces stay in the browser and are not uploaded. Account notes you publish are public. |
| Timeline noise | It does not fold the x.com timeline. Scout shows a short deck of posts from accounts you follow. | Rules run on the x.com timeline and can be limited to For You. |
