Verify Readiness
Section titled “Verify Readiness”Enter credentials only in the app’s provider fields, or follow its sign-in flow. Validate or re-check status, assign the primary provider, and run a short question plus screenshot test. Review automatic failover if you configure a backup.
The direct-download app supports local Gemma and external subscription integrations; the Mac App Store app does not. ExtraBrain AI needs an eligible plan and positive credit balance. External API and subscription costs remain with those accounts.
Review data handling before using sensitive material, and Troubleshooting if validation fails.
