ZeroMark helps you curate taste from your saved posts. It is a web app at zeromark.io that reads the X bookmarks you connect, gives you two lines on each, and lets you keep it, let it go or snooze it with one key. What you keep and what you let go become your taste, and Claude, ChatGPT and Gemini can read it.
Who it is for
People with hundreds or thousands of X bookmarks they meant to come back to. Founders, researchers, writers and builders who save faster than they read, and who want their AI assistant to know what they actually kept, not just what they once tapped.
How it works
Connect X, read-only. Sign in with X, Google or an email link. ZeroMark syncs your bookmarks. It can read them, and your likes when that import is on. It never posts, likes, follows, messages or deletes anything on X.
ZeroMark reads them first. Each save gets two lines and a field. A quote post includes the post it quotes. The two lines are a short summary: what the post says, and why it might still matter.
You decide, one key each. D for done, X for let go, S for snooze, U to undo. On a phone, swipe. The open queue ends on a Zero card.
Your taste goes where you work. What you keep becomes Living Memory. You can export the library as a file, and send keeps to Notion or Obsidian. A connector lets Claude, ChatGPT and Gemini read what you decided. The tools that read a save are read-only. The one thing an assistant writes is a build brief, the first time it asks. ZeroMark is listed in Claude's connector directory: open ZeroMark there and press Connect.
What ZeroMark is not
A few products have similar names. They are not us. ZeroMark is not ZMark, not the defense company at zeromark.com, and it is not Zero Bookmark Manager.
ZMark (zmark.app) is a self-hosted bookmark manager and link directory. Different product, different team.
The defense company at zeromark.com is not a bookmark app. Different product, different team.
Zero Bookmark Manager is a Chrome extension for browser bookmarks. Different product, different team.
ZeroMark is a web app, not a Chrome extension for browser bookmarks, not a read-later archive and not a backup tool. It works on X bookmarks, in your browser, and its job is getting the pile to zero. There is nothing to install.
