Quick answers

The most common questions, answered on our full FAQ page.

View all FAQs
Is practice really unlimited, and do I pay only once?

Yes. In the Windows app you can take as many AI quizzes and read as many AI explanations as you like, with no usage limits.

How is PromGee different from other English learning apps?

Instead of generic levels, PromGee lets you drill one skill at a time — prepositions, tenses, articles, punctuation — with an AI explanation after every answer.

Which platforms are supported?

PromGee runs on Windows 10 and 11.

Do I need an internet connection?

Yes — quizzes and explanations are generated by AI, so an internet connection is needed while you practice.
