Your Second Brain lives in 1 cloud. Each of your AIs must be able to reach it. Pick the guide for your AI. Every guide was tested on 6 October 2026.
Claude Code, the ChatGPT desktop app (Codex), Cursor and Hermes can edit your folder. You give each a short paragraph and permission to use the folder.
Claude on claude.ai and Grok Bot reach your cloud through a connector. They add new notes and the app files them. The connector must be to the same cloud as your Second Brain.
If an AI cannot reach your cloud at all, ask it to write the entry and press Paste a note in the app. Nothing is lost.
