Riffle turns a lecture into notes you'll actually read — and flashcards you actually approve. Most AI study apps write your cards for you and drop them straight into a deck. You find out six weeks later that half of them were wrong. Riffle shows you every card first. Keep the good ones, cut the rest. The step isn't skippable, because it's the whole point. HOW IT WORKS 1. Capture — record a lecture as it happens, snap a page of a textbook, upload an audio file, or just type the topic you're studying. 2. Read — you get a clean, structured summary with the full transcript kept underneath it. The source is never thrown away, so a card you doubt in six weeks has something behind it to check. 3. Drill — turn the note into flashcards when you're ready, approve them one by one, and study the deck. RECORDING THAT STAYS ON YOUR PHONE Live lectures are transcribed on your device, as you speak. The audio is never uploaded and never written to disk — that absence is the feature, and it's why a two-hour lecture records the same as a two-minute one. NOTES THAT KEEP THEIR SOURCE A note is a summary of material you still have. The transcript sits underneath it, always. Read the summary when you're revising; drop into the transcript when you need the exact words. STUDY WITHOUT THE CEREMONY Every session is the whole deck, shuffled, and it ends on a score. No streak to protect, no daily quota telling you you've fallen behind. Swipe right if you knew it, left if you didn't. DESIGNED, NOT DECORATED The interface is monochrome on purpose. Colour means one thing in Riffle — how well you knew the card — and it's never spent on anything else.
