FAQ

Common questions about ChatGPT on B77

Do I need a paid ChatGPT plan?

Most B77 apps work on the free ChatGPT tier. Some advanced features (long-running jobs, scheduled queries) require a paid plan — those are flagged on each app page.

Is my data safe?

Every B77 app uses OAuth tokens — we never see your credentials, and you can revoke access anytime. EU-hosted by default; all listings flagged GDPR-safe.

Can I use multiple apps at once?

Yes. ChatGPT can call any installed app mid-conversation. Just describe what you want — it picks the right tool.
