Simple when you need the gist. Study Mode when you need to remember it.

Yes — cancel from your account settings in one click. You'll keep Study features until the end of the current billing period.

One popcard is one source you "pop" — a YouTube video, an article, or a block of notes. Each pop generates a deck of multiple cards.

Simple Mode gives you plain-English cards with the key ideas, examples, and analogies — for when you want the value quickly. Study Mode generates more cards mixing easy recall, applied questions, and harder synthesis — built for revision.

Study is already priced for students. We'll add free-month student programs and bigger discounts when we launch the school tier — reach out from your school email if you're keen to test it.

Your content is yours. We don't sell data, don't train models on your popcards, and use privacy-friendly analytics (Vercel Web Analytics) with no cookies.

Study includes 100 popcards per month with a soft daily cap of ~15 and a 60-minute limit on individual videos. We'll let you know if you ever approach a limit — no surprise charges.
