Learn how to keep flashcards together by topic and chapter
Group cards by unit so related ideas stay side by side, then turn your own PDFs, slides, notes or photos into flashcards with spaced repetition.
Why grouping flashcards matters
Most students run into trouble with how to keep flashcards together once a course grows past a few weeks of notes, slides and readings.
- Name each set by course, unit and topic so it is easy to find later.
- Keep one topic per set, roughly the material from one lecture or reading.
- Note the source page or slide on each card for quick re-checking.
- Review related sets together now and then to separate similar ideas.
Sets built by topic
Generate each set from one chapter or lecture so related cards stay together and are easy to review in one sitting.
Works from your files
Upload PDFs, DOCX, PPTX, plain notes or photos of pages, and get flashcards drawn from that exact material.
Spaced repetition built in
Cards come back on a schedule, so a grouped set keeps getting revisited instead of fading after one session.
How it works
Sort your material
Group PDFs, slides and notes by chapter or unit before you upload anything.
Generate one set per topic
Upload a single topic at a time to create a focused flashcard set you can study on its own.
Review and fill gaps
Study each set, then add or regenerate cards for the topics that keep slipping.
Grouping cards by chapter or unit keeps related terms in the same place, so you can review what you just covered and notice where your understanding is thin. Mixing a few related sets later also helps you tell similar concepts apart.
Labeling each set with its course and unit, and noting which slide or page each card came from, makes it much faster to go back and fix a card that keeps getting missed.

Frequently asked questions
How should I split one course into flashcard sets?
Split it by unit or chapter, so each set covers one topic you can finish in a single sitting. Smaller, focused sets are easier to keep organized over a semester.
How many flashcards should be in one set?
Aim for the material from one lecture or reading section, which keeps each study session focused. If a set feels too long to finish, split it into two topics.
Can I export my flashcard sets to Anki?
Yes, export to Anki is included in the Plus plan, which costs $99.90/year or $9.99/month. The free plan lets you study in the browser but does not include exports.
