Flashcards have been an effective learning tool since 1834, but their power increased dramatically with the discovery of spaced repetition in the 1960s. The principle is simple: review cards just before you would forget them, and the brain encodes the memory much more deeply than re-reading. Modern apps like Anki and Quizlet build entire ecosystems around this, but the underlying algorithm — known as SM-2 — can be replicated in any browser with no signup, no cloud, no data leaving your device. This tool offers SM-2 review plus three alternative study modes (cram, quiz, typing) so you can match the technique to the material.

Как пользоваться (по шагам)

1. 1

   Create a deck

   Name it after the topic (Spanish verbs, anatomy terms, JS APIs). Decks are independent — different review schedules don't interfere.

2. 2

   Add front and back text for each card

   Front is the question or prompt; back is the answer. Bulk-paste from CSV/spreadsheet works for big imports.

3. 3

   Review on the schedule the SM-2 algorithm builds for you

   Cards you find easy get pushed weeks out; ones you stumble on come back tomorrow. Honest grading is the key — don't grade 'easy' to avoid work.

Как это работает

After each card, you grade your recall: Again (forgot), Hard (struggled), Good (recalled), or Easy (instant). The algorithm increases the gap between reviews by a multiplier called the 'ease factor' — starting at 2.5. Good answers extend the next review (1 day → 6 days → 14 days → 35 days...), while Again resets to 0. Over weeks, you stop seeing well-known cards and only the shaky ones surface. The tool tracks per-card state in localStorage and shows daily statistics (streak, accuracy, mastery progression).

Когда пригодится

Language vocabulary (the canonical use case — 80% of Anki's user base learns languages), medical school memorization (anatomy, drugs, diagnoses), bar exam prep, board exam prep, technical interviews (algorithms, system design facts), historical dates, music theory, programming syntax for new languages, and any material that requires recall rather than understanding. Less useful for skills that need practice (musical instruments, sports, writing) — those need different practice loops.
