How to use X bookmarks in ChatGPT, Claude or Gemini

Hand an assistant the decisions you already made. A dump of every save is the wrong start.

Why a dump of every bookmark is the wrong start

Pouring every bookmark into a chat hands the model what you hoped to read: thousands of saves, all equal, many cut off mid-sentence. Taste is the decisions you already made. ZeroMark puts a short summary on each save, you mark Done or Let go, and those decisions become Living Memory. The connector hands an assistant that record, not the raw guilt pile.

What you need first

1. A ZeroMark account. Start here. Free for your latest 150 saves, then $4.99 a month or $39 a year.
2. A short triage pass on those saves so "kept" means something. One key each: Done, Let go, or Snooze.
3. An assistant that can take a connector (Claude, ChatGPT, Gemini CLI, Cursor, Claude Code, or Perplexity on Pro, Max or Enterprise) or any chatbot that accepts a file upload.

Six steps to connect

Step 1. Open the connector settings in ZeroMark

In ZeroMark go to Settings and find Connect to Claude, ChatGPT or Gemini. It shows the server URL https://www.zeromark.io/api/mcp and can mint a personal key. A key is shown once, so copy it before you leave the page. Prefer sign-in when the assistant offers it. A key is the fallback. Use the www host from Settings.

Step 2. Claude (claude.ai, Desktop, apps)

Open ZeroMark in Claude's directory and press Connect. That signs you in to ZeroMark, so there is no key to paste. If your workspace does not show the directory, open Settings, then Connectors, then Add custom connector, and enter https://www.zeromark.io/api/mcp. Allow access on the ZeroMark page. The one write is a build brief, the first time it is asked. The custom URL is the fallback. The directory is the path to try first.

Step 3. ChatGPT

Add a custom connector with URL https://www.zeromark.io/api/mcp and sign in. Allow access. The one write is a build brief, the first time it is asked. Deep research can use the same connector. Disconnect later from ChatGPT settings or revoke the key in ZeroMark Settings.

Step 4. Gemini CLI, Claude Code, Cursor

Paste this to your agent, or add the URL by hand:

Set up ZeroMark for me by following https://www.zeromark.io/docs/connector/agent-setup.md

Or add https://www.zeromark.io/api/mcp yourself and sign in, or paste a key from Settings as Authorization: Bearer zm_mcp_YOUR_KEY. Gemini CLI reads that from ~/.gemini/settings.json:

{
  "mcpServers": {
    "zeromark": {
      "httpUrl": "https://www.zeromark.io/api/mcp",
      "headers": { "Authorization": "Bearer zm_mcp_YOUR_KEY" }
    }
  }
}

That is Gemini CLI. The Gemini app's custom apps are limited to some accounts in the US, the same limit named on the connector guide, so this page does not treat the Gemini app as available to everyone.

Step 5. Check it worked

Ask the assistant which ZeroMark tools it has. It should list thirteen, including search_saves, get_save, get_taste, get_memory, get_map, get_podcast, get_brainstorm, get_build_brief and weekly_question. If they are missing, the sign-in has not finished.

Step 6. Ask something that needs your taste

• What have I kept about pricing in the last month?
• Which voices do I keep most, and which do I let go?
• Read my Living Memory and tell me what changed this quarter.
• Pick the one open save worth acting on this week.

The assistant should say how many of your decisions its answer rests on, and say so when there are too few to call it taste.

No connector? One file

Settings, Export everything, AI-ready file. You get one Markdown file: a short note to the assistant, every save grouped by stage with its link, then your Living Memory. Upload it to any chatbot that takes a file. This is the honest fallback when an assistant has no connectors.

What stays private

• Read-only on a save. Nothing the assistant does can mark Done, let go, snooze, edit a note or delete, in ZeroMark or on . The one write is a build brief, the first time it asks for one.
• Your library only. A key or sign-in opens exactly one library, its owner's.
• Revocable in Settings. The next call after revoke is refused. Keys are stored only as a one-way hash.
• Counted, not recorded. Each call logs the tool, the time and a count. What was asked is never kept.
