FlashCards

Flashcards with spaced repetition, practice tests with exam mode & timers, streaks, stats, CSV/JSON import-export, and device sync.

FlashCards is a free, no-nonsense study tool for building your own flashcard decks and practice tests — with spaced repetition, exam simulation, and progress tracking built in. STUDY SMARTER WITH SPACED REPETITION Rate each card Again, Hard, Good, or Easy after seeing the answer, and FlashCards schedules your next review automatically — so you spend time on what you actually forget, not what you already know. A "Review Due" button surfaces exactly the cards ready today. BUILD YOUR OWN DECKS • Add cards with a front and back, organize them into categories, and star the ones you find difficult • Search instantly across hundreds of cards • Color-code decks so you can tell them apart at a glance TURN ANY DECK INTO A PRACTICE TEST One click converts a flashcard deck into a multiple-choice test. FlashCards automatically generates plausible wrong answers by matching them to the type and category of the correct one, so tests are genuinely challenging — not a giveaway where the right answer looks nothing like the others. EXAM MODE, TIMERS & RANDOM SUBSETS • Exam mode hides right/wrong feedback until you finish, just like the real thing • Set a time limit — unanswered questions count against you • Draw a random subset of questions each attempt (great for a 500-question pool you want to drill 25 at a time) • Review every question you missed at the end, and retake just those — without it skewing your real test stats TRACK YOUR PROGRESS Study streaks, a recent activity feed, and per-test stats (attempts, best score, average, accuracy) show exactly how you're improving over time. IMPORT FROM A SPREADSHEET Already have your material in Excel or Google Sheets? Import a CSV in seconds. FlashCards checks for duplicates before importing and shows you a preview first. A built-in CSV Help Center includes downloadable templates and a ready-to-use prompt for generating flashcards with an AI assistant. YOUR DATA, YOUR DEVICES Everything syncs automatically across your signed-in Chrome browsers. Export a full backup to JSON anytime, or export any deck as a CSV to use elsewhere — your content is never locked in. PRIVATE BY DESIGN FlashCards only asks for the "storage" permission — nothing else. No accounts, no ads, no tracking. Just your cards, stored on your own devices.
