Claude & ChatGPT
Connect
Go to Settings → Connect Claude. On claude.ai, add a custom connector with the address shown there; sign in to HeyOtto and click Allow. In ChatGPT, add the same connector. For Claude Code or Claude Desktop, create a personal key.
You can link a key to one brain: then your AI only sees that brain. You can always revoke it.
What your AI can and can't do
Your AI reads your overview, companies, tasks and people, and can create and tick off tasks and add notes, ideas, knowledge and meetings. It can never send mail or delete anything.
Skills and scheduled tasks
For each connected source you can download a Claude skill (also all together as a zip). It describes how your AI works with that source and which rules apply. In Settings you'll also find ready-made instructions for scheduled tasks, such as a daily run.
