Does UsePro call the OpenAI API?

No. UsePro works through your signed-in ChatGPT web session in a dedicated minimized Chrome window. ChatGPT and its availability remain separate from UsePro.

No new model subscription is included or required. UsePro is a one-time $18 purchase; you bring your own ChatGPT account and subscription.

Where does my work run?

The companion, local queue, transcript rendering, and browser worker run on your machine. There is no hosted job database, dashboard, or remote prompt archive.

What do I install?

The local pack includes the @UsePro Codex plugin, a dependency-free companion, and a Chrome extension that keeps a signed-in ChatGPT worker ready in the background.
