Connect OpenAI Or ChatGPT Subscription

ExtraBrain offers OpenAI API access and a ChatGPT subscription connection using Codex. They use different account and billing paths.

OpenAI API Key

1. Open Settings → AI Providers and open OpenAI API key.
2. Enter your OpenAI key in the app’s credential field.
3. Choose a supported primary analysis model and reasoning effort where offered.
4. Validate and confirm readiness.
5. Assign it as primary or backup and test a question and screenshot.

An API key requires API access; a ChatGPT subscription is not itself an API key balance. Check account model access, quota, and project policy if validation fails.

ChatGPT / Codex Subscription

This integration is available in the direct-download app and is unavailable in the Mac App Store build.

1. Open the ChatGPT/Codex subscription provider in AI Providers.
2. Follow the displayed sign-in flow or re-check the existing sign-in.
3. Confirm the connected account status and choose an available model.
4. Review any Pro gate on model controls.
5. Assign the provider role and run a test analysis.

The app uses supported ChatGPT subscription access without an OpenAI API key. Model lists and account limits depend on the connected account; use the current provider page rather than an older model list.

Troubleshooting And Data

For API errors, verify the key, model, network, and optional endpoint settings. For subscription errors, complete the app’s sign-in or recovery action and re-check status before retrying. Do not paste credentials into support messages.

Requests can include prompts, transcripts, document excerpts, tool context, and screenshot images. See AI provider roles and failover and data handling.
