What are AI credits?
Every lesson, quiz, flashcard set, podcast and tutor reply uses a few credits, depending on how long your material is. A typical lecture turned into a full lesson uses about 20–40 credits. Credits reset on the 1st of every month, and you’ll always see your balance in the sidebar.
Questions, answered.
PDFs, PowerPoint and Word files, photos of notes, audio recordings of lectures, YouTube links and web pages. You can also just type a topic and Cramby will teach it from scratch.
Cramby doesn’t stop at notes. It turns your material into a short course, tracks which concepts you actually get wrong, and plans what to study next — so the second session is smarter than the first.
Lessons, quizzes and flashcards are built from your material, and explanations point back to the part of your notes they came from. When Cramby isn’t sure, it says so. You can edit everything.
Yes — formulas render properly, worked examples are step by step, and quizzes can check reasoning, not just final answers.
No. Cramby works on its own. If you use Clerval, you can optionally connect it so Cramby can use your Clerval context.
Yes. The free plan includes unlimited lessons and a monthly allowance of AI credits. Pro adds far more credits, deep mode, exam plans and bigger uploads.
