Your OpenAI setup, kept separate
Sign in with ChatGPT for the experimental Codex paths. Use a Platform key for compatible /v1 tools. Choose a path to see where n8n, your credential, and the destination connect.
ChatGPT sign-in and Platform API keys do different jobs. Relmio never turns one into the other.
How each option connects
See the sign-in, connection, and destination for each path.
Unofficial n8n option
Before anything changes
Each option shows which credential it uses, where it connects, and what it reaches. Before writing to a VPS, the wizard verifies the server, shows the plan, and asks you to approve it.
Hosted chat
This chat uses the account you connect in this browser. Relmio forwards credentials only with your request; the server does not keep a reusable session.
The hosted chat needs the open-source Sign in with ChatGPT extension to complete the secure OAuth handoff. Install it for Chrome or Firefox, reload this page, then connect again.
Using the local npm wizard? It handles its own localhost callback. If an OAuth extension intercepts that callback, temporarily disable it during local sign-in.
This browser encrypts the credentials it stores. Disconnect to remove the local session.
Hosted test lane
gpt-5.4-mini
Encrypted in this browser. No tools, files, commands, or external browsing. The demo keeps only the latest six exchanges in this tab.
Your private test lane is ready.
Connect ChatGPT, choose a starter, or ask your own question.
Response state: Ready.
Safety boundary
The hosted chat is a browser demo. The n8n installer remains a local wizard that deploys a separate sidecar without changing your existing n8n container, image, or workflows.
