Shared by choice, not by default.

AI chats stay private. Every contribution is explicit, every shared context has a visible audience, and every record keeps its origin.

The defaults

What the rules are

Nothing is imported automatically. Connecting an AI does not hand over your chat history. A record appears only when you send something to the bot or explicitly ask your AI to save it.
Every shared context has a visible audience. Everyone who can read it is listed right on it, and anything that widens that audience waits for your yes.
Every record keeps its origin. Who added it, where from, when.
Deletion is deliberate — and reversible for 7 days. It works from every entrance, and “undo my last deletion” works too.
Invitations go person to person. Sharing sends a card to your own Telegram; the other person sees what the context is before joining, and joins only by pressing the button themselves.

Good to know

The assistant says it cannot save? Almost always it is the app mode, not the connection: in ChatGPT, saving works in the working mode. Or save the same thing from Claude.
A new ability does not show up? Assistants read the tool list once, when they connect. Reconnect and start a new chat.
Something stopped working? Reconnect first — it re-runs sign-in and rebuilds the link. It clears most stale states.
Deleted a Telegram message? That is not deletion from Contexter — here it is deliberate, and reversible for 7 days.

In writing

What we process and why is written down in the Privacy Policy; the rules of the road are in the Terms of Service; the providers we rely on are listed on the Subprocessors page.
