Is it free?
Yes. The student portal account is free, and connecting your AI uses that same account. There's no checkout. Your AI account is separate. ChatGPT, Claude, Claude Code, and Codex each have their own plans, and some plans or workspaces limit custom connectors.
What can my AI see?
Only the Context Cards and roadmaps you tick for that AI in the portal. Nothing is selected by default. A selected card includes its supporting context. Access belongs to that AI account, so it covers all of its chats, not just one project. Your AI provider processes whatever you share with it.
Can my AI change my cards?
No. Your AI can read the cards you selected, but it can't edit, delete, or create them. Every change goes through you. Ask your AI for a draft, then review it and save it yourself in the portal. Nothing is sent, posted, or published on your behalf.
How do I disconnect?
Open Context Cards → Connect your AI in the portal, choose the AI, and select Disconnect access. Its next request is refused. Disconnecting doesn't erase what that AI already read in an earlier chat, so leave private cards unselected if you don't want them shared.
