Record the lecture. Own the exam.
Humble Zen turns every lecture, reading, and YouTube explainer into summaries, flashcards, and quizzes — for a one-time price that costs less than one month of the subscription apps.
Lecture recording
Hit record in class. Transcription runs on your iPhone — even with no signal in the basement hall — and a clean summary is waiting before you're back in your dorm. Quiz yourself before the midterm instead of re-reading a 90-minute transcript.
Exam prep
Import lecture slides and readings as PDFs. Generate flashcards for every topic and use quiz mode to find your weak spots before the exam does. Review on your laptop with the companion web app.
YouTube lectures
Paste the URL of that hour-long online course video. Get the full transcript, a summary, and a flashcard deck without watching it twice at 2× speed.
Study groups
One person records; everyone benefits. Share a note link and your whole group gets the transcript, summary, flashcards, and quiz in their browser — no app, no accounts.
The math your subscription app hopes you never do
The popular AI study apps charge $16–20 every month — $160+ per school year, every year. Humble Zen Pro is $19.99 once, with 300 AI credits included and packs from $0.99 when you need more. Credits never expire. Summer break costs you nothing.
