Every agent, one warm table.

Kotatsu gives ChatGPT, Claude, Codex and your other agents one shared memory, your connected apps and one task list.

What sits on the table

One memory, your apps and one task list, shared by every agent.

A memory that shows its sources

Your agents read and write one Markdown brain: the people, companies, notes and tasks you keep.

Each fact cites a proof, the stored source item it came from. Tasks live there too, so every agent works from one shared list.

Your apps, connected by you

Gmail, Google Calendar, Drive and Docs, Contacts and Tasks through one Google connection, plus Pocket, Notion, Slack, GitHub and finance through Payman.

Nothing is read until you connect it on the site.

Every agent, with your say-so

Kotatsu is a remote MCP server with OAuth sign-in. It works with Claude Code, Codex, ChatGPT, the Claude app and any MCP client, and agents without MCP can pair.

You approve each agent in the browser and can revoke it on the Agents page.

Setup

Your agent does the setup in three steps.

  1. Save the rules

    Your agent saves the short Kotatsu rules word for word, so every session starts the same way.

  2. Connect

    It adds Kotatsu as a connector and you approve it in your browser.

  3. Check

    It calls whoami and tells you which Kotatsu account it is on.
