Local and self-hosted installations can connect personal ChatGPT accounts through OpenAI’s open-source plan-sharing flow. The hosted Tuturuuu service does not enable this integration. Hosted support needs OpenAI’s separate access path; open-source licensing does not establish hosted eligibility.

​
Enable your installation

Use a Node.js web runtime with persistent, private filesystem storage. Set these server environment variables and restart the web app:
Mount that directory persistently for containers. Restrict it to the runtime owner; directories use 0700 and credential files use 0600 on Unix. The default path is ~/.config/tuturuuu/chatgpt. Never place it inside public assets, source control, logs, analytics, backups accessible to workspace members, or browser storage. Serverless installations with ephemeral filesystems are not supported by this flow.

​
Connect your account

Sign in to Tuturuuu and open ChatGPT plan beside the chat model picker. Expand the connection instructions to get a command containing your Tuturuuu user UUID. From the repository root on the computer running your browser:
The utility opens the system browser at OpenAI’s Continue with ChatGPT flow. It binds a random-port callback to 127.0.0.1, checks state, PKCE, signature, issuer, audience, expiration and nonce, and verifies ChatGPT plan permission. It does not require an OpenAI API key or client secret. Never paste tokens into Tuturuuu’s browser UI or support conversations. Each account/workspace registration has its own issued client ID and credential record. To reconnect a saved registration, add --client <ISSUED_CLIENT_ID>. Do not copy one account’s client ID onto another account’s tokens. For a remote self-hosted server, complete OAuth locally, transfer the protected credential file over SSH to a private temporary path, then run the import utility on the server with the same Tuturuuu user UUID:
The credential filename is the SHA-256 digest of the Tuturuuu user UUID followed by .json in CHATGPT_SUBSCRIPTIONS_DIR. The import preserves the server’s own host ID. Securely remove the temporary transfer file after import. Stop using the local session so only the server refreshes the imported rotating refresh token. OpenAI currently does not offer host-specific revocation for transferred sessions.

​
Use your plan

Refresh the ChatGPT plan menu and select an account and model. The catalog is read from OpenAI with that account’s OAuth token; gateway plan allowlists do not filter the subscription catalog. Using ChatGPT plan remains visible near the composer, with a link to Manage usage. ChatGPT mode supports streaming chat with text and compatible image/file inputs. Models use their default reasoning settings. It sends the required conversation history to the public Responses API with store: false and stream: true. It does not use ChatGPT’s private backend API. ChatGPT mode currently does not run Mira workspace tools, memory-provider calls, web search, voice, transcription, or image generation. Select a Tuturuuu model explicitly to use those existing features. Unsupported audio/video uploads are filtered before upload, existing thread audio/video files are excluded, and explicit audio/video inputs are rejected before subscription inference. Subscription requests bypass Tuturuuu model allocation, credit preflight, output credit caps, memory-provider wrappers, and credit deductions. New conversations get a local title derived from their first message, without a hidden AI title call. History stays in Tuturuuu under its existing user ownership checks. The request’s captured model selects both the endpoint and authentication, even if the composer selection changes while sending. The funded endpoint rejects chatgpt/ models before authentication, model fallback, persistence, or credit work. Regression coverage lives in mira-chat-transport.test.ts and subscription-route.test.ts. ChatGPT plan and app limits still apply. A failed, incomplete, or interrupted stream is not a completed answer. Tuturuuu never automatically retries it using Tuturuuu-funded AI. Follow Manage usage, reconnect the account if necessary, or explicitly choose another model. Disconnect clears that registration’s local tokens and attempts remote refresh-token revocation. If revocation is not confirmed, disconnect the app in ChatGPT Settings too.

​
Operations and verification

Filesystem locks serialize refreshes across workers sharing the directory. If a process dies while holding a .lock directory, requests fail closed after thirty seconds. Confirm no server worker or connection utility is using that registration before removing only its stale lock directory. Do not delete credential files to clear a lock. Use a shared filesystem that provides atomic directory creation and rename; separate containers with copied sessions must not independently refresh. Focused checks:
Require type-check, lint, test, and the owning web build in CI for the exact commit; do not run bun check or builds locally. Mocked tests and a successful CI build do not establish real subscription eligibility. Complete a real OAuth connection, choose an account-specific model, receive a completed streamed answer, verify persisted history, and confirm that Tuturuuu credits were not charged before claiming live provider verification.
