Turns lectures and PDFs into notes and flashcards

What it does
Turbo AI (formerly TurboLearn) converts whatever a student has — recorded lectures, YouTube videos, PDFs, slides — into structured notes, flashcards, quizzes, and even audio recaps, with a chat tutor that answers questions from the uploaded material.
The free tier covers 2 hours of lecture audio, limited flashcards, and a handful of quizzes per month. Paid plans start at $5.99/mo, with an unlimited tier around $12.99-19.99/mo depending on billing.
It reports over 5 million students and professionals, riding the same student-workflow wave as NotebookLM while staying exam-prep-specific.
From the AXIS Launch team
Meeting students at the artifact they actually possess — a phone recording of a lecture — is smarter than assuming clean source material. If you claim this: what does semester-over-semester retention look like once exams end, and how do you keep generated quizzes from teaching errors?
