Most flashcard tools dump everything they read into your deck. Klarrity reads the same source — a page, a PDF, a YouTube clip — and writes only the cards you still need.
Less, but better
Study Klips
Open any YouTube video. Pick the last 30s, 60s, 2m, or a manual range. Klarrity grabs only that transcript window — and every card links back to the exact moment.

Define the isovolumic phase.
Which valves close to produce S1?
Klarrify
Klarrify runs a 5-question diagnostic on your source. You see what you know. Klarrity builds cards only on what you don’t.
Question 2 of 5
What term describes the brief moment when all four heart valves are closed and ventricular volume does not change?
After the quiz
No cards on what you already know. That’s the whole point.
Less, but better — applied to your source, and applied to your deck.
No copy-pasting into a chat window. No re-reading the source. Klarrity stays out of your way until you ask for cards.
Highlight text on any page, screenshot a region, or grab a YouTube clip. Klarrity reads it where it lives.
Generate directly, or run the Klarrify diagnostic and build only from the gaps the quiz exposes.
