How the cards are found
Three patterns, in order of how reliable they are. Anything already written
as Q: and A: is taken as-is. Then glossary lines —
term: definition, or with a dash. Then definition sentences in the
prose: “Mitochondria are the powerhouse of the cell” becomes
“What are mitochondria?”
The filters matter more than the patterns. A definition finder with no quality gate produces a deck full of cards like “What is it?” — “the same as before”, and one card like that costs more trust than three good ones earn. So terms have to be one to six words, definitions three to sixty, and anything starting with it, this or there is thrown away.
No repeated cards
Textbooks restate the same definition in three places. Near-duplicates are detected by comparing the meaningful words in each card — ignoring the, of, and plural endings — and dropped. Twelve good cards beat forty with the same fact in it four times.

Want this while you're reading, not after?
The StudyFrame extension makes cards from whatever page you're on, answers questions you snip off the screen, and builds practice tests that come back harder on what you miss.
Free to install. 3 uses a day at no cost, more if you study on a streak.
Questions
- Is my file uploaded?
- No. Everything here — reading the file, finding the cards, building the export — happens in your browser. There is no server in this page.
- Why did it only find a few cards?
- Because it would rather give you eight good cards than fifty bad ones. Narrative prose with no definitions in it genuinely has few flashcards in it; glossaries, lecture slides and definition-heavy chapters produce the most.
- Can I edit them before exporting?
- Yes — every card below is editable. Changes are included in the download.
- Does it use AI?
- Not by default, so it works in every browser and returns cards instantly. If you are on a recent Chrome with the built-in model available, there is a button to have it tidy the wording — and if that is not available, the button does not appear and everything still works.
