Active recall is the act of trying to retrieve an answer from memory before you check it, rather than passively rereading notes. The effort of pulling a word's meaning out of your head is what strengthens the memory, which is why it consistently beats highlighting or copying definitions. Flashcards are built for this: you see the prompt, force yourself to recall the answer, then flip the card to confirm. In this tool's flashcard mode, each card shows the word first and hides the definition behind a flip animation, so you commit to an answer before revealing it. You then self-grade with "Got it," "Didn't know," or "Skip," which keeps you honest about what you actually knew. Build a deck above and start a flashcard session to put active recall to work.

Both modes review the same deck but test recall in different ways. Flashcard mode shows one word at a time and asks you to recall the meaning from scratch, then flip the card and self-grade whether you got it right — it builds free recall, the harder and more durable skill. Quiz mode is multiple choice: it shows a word with four definitions, one correct and three pulled at random from your own list, and tells you instantly if you picked right. Recognition is easier than free recall, so quizzes feel more forgiving and are good for warming up or checking progress. Because the wrong options are real definitions from your deck, the quiz also exposes words you keep confusing with each other. Quiz mode needs at least two words to generate choices. Add words above, then alternate both modes for the best coverage.

A focused working set beats a giant pile. Most learners retain more by keeping roughly 15 to 30 active words in rotation and retiring the ones they consistently get right, rather than cramming hundreds in a single sitting. Short, frequent sessions also outperform one long marathon, because spacing reviews across days lets memory consolidate between rounds — the core idea behind spaced repetition. Trying to drill a hundred new words back to back leads to interference, where similar terms blur together and nothing sticks. This tool supports that approach: it keeps lifetime review stats per word so you can see which ones you've mastered and remove them, keeping your deck small and active. Add a manageable batch above, review it over several short sessions, and clear out the words you've locked in before adding more.

A bare word-and-definition pair is harder to remember than a word anchored in a sentence you can picture. Context gives the term a scene, a grammatical role, and an emotional hook, all of which create extra retrieval paths to the meaning later. An example also captures nuance a short definition misses — how the word is actually used, what it collocates with, and its register or tone. That is why this tool gives every entry an optional example sentence field alongside the required word and definition, plus an optional one-to-five difficulty rating shown as stars. When you study in flashcard mode, your example appears with the definition on the back of the card, reinforcing the word in real use rather than in isolation. Add a vivid sentence as you create each word above to make it far easier to recall when you need it.

Getting a word right once does not move it into long-term memory; seeing it again after a delay does. Each correct retrieval is a single rep, and memories fade unless they are refreshed at growing intervals — the principle behind spaced repetition. A word you ace today but never revisit can be gone within days, while one you re-test tomorrow and again later sticks far longer. That is why reviewing across multiple sessions matters more than nailing a word in one round. This tool keeps lifetime stats on every word — total reviews plus your correct and incorrect counts — not just a single session score, so you can spot which words are genuinely solid and which only looked easy once. Use that history to decide what to keep drilling and what to retire from your deck above.
