Connect Anthropic Or Claude Subscription
ExtraBrain supports Anthropic API keys and a separate Claude subscription integration. Use the connection that matches your account.
Anthropic API Key
Section titled “Anthropic API Key”- Open Settings → AI Providers → Anthropic API key.
- Enter your key in the app.
- Choose a supported model and validate access.
- Assign it as primary or backup.
- Test a question and screenshot analysis.
Check the key’s account, quota, model access, and network policy if validation fails. An external Claude subscription is not an Anthropic API balance.
Claude Subscription
Section titled “Claude Subscription”This integration requires the direct-download app; it is absent from the Mac App Store build.
- Open the Claude subscription provider.
- Follow the displayed sign-in or re-check flow.
- Confirm that the subscription connection is ready.
- Choose an available model and review any Pro gate on model controls.
- Assign its role and run a short test.
Supported Claude subscription access does not require an Anthropic API key in ExtraBrain. Use the provider page’s current account status and available models. If signed out or limited, complete the displayed recovery action before retrying.
Context And Costs
Section titled “Context And Costs”Anthropic or Claude receives the context needed for your request, which can include transcript text, prompts, document excerpts, tool context, and screenshot images. Its account policies, billing, and limits remain separate from ExtraBrain Pro and ExtraBrain AI credits.
