← All hosts TurnStyle · ChatGPT

Your memory, inside ChatGPT.

Connect once. From then on, ChatGPT can search everything you have saved, open a summary down to the exact words, and save new decisions as they happen — masked for secrets and personal data before anything is stored.

2 · Add it by URL

1. In ChatGPT (web app — not the mobile apps), open Plugins in the left sidebar and press + for New Plugin. If Plugins is not shown, turn on Developer mode under Settings → Connectors → Advanced first.
2. Name it TurnStyle. Connection: Server URL, and paste this URL. Authentication: OAuth. ChatGPT discovers the sign-in from the URL — leave the advanced OAuth settings as discovered; there is no client ID or secret to enter:

3. https://mcp.thatapp.io/api/mcp

4. Tick I understand and want to continue and press Create. Sign in on the ThatApp page and press Allow.
5. In a chat, open the tools menu, enable TurnStyle, and ask about earlier work. Saving (memory_save) asks you to confirm each time — that is ChatGPT's own rule for write actions.
6. To disconnect: Plugins → TurnStyle → Delete.

3 · What is captured

What is captured: what the assistant chooses to save. TurnStyle gives this host one write tool, memory_save, which stores the exchanges the assistant sends to it (up to 50 messages per call, 32,768 characters each). Ask the assistant to “save this to my memory” at the moments that matter, or tell it once to save decisions as they happen. Everything else in the chat stays where the host keeps it. Full automatic capture from this host is not available yet.

On ChatGPT: write-tool (write actions on Business/Enterprise/Edu; Pro is read-only; Plus documented inconsistently — measured result pending).

4 · Your history

Export your history from the provider (ChatGPT: Settings → Data controls → Export data; Claude: Settings → Privacy → Export data), then drop the zip or its conversations.json (up to 50 MB) into the AVA chat and ask AVA to import it. AVA reports what it found before writing anything, imports on your yes, and tells you when it is folded and searchable. Larger exports: ask support. The AVA chat is at https://thatapp.io/ai-chat. Everything already saved is reachable from every host you connect — the memory is one place, the hosts are doors.
