Vocabulex: AI Flashcards

Ready to learn and remember better? Vocabulex is an AI-powered vocabulary builder with adaptive spaced repetition, designed to match how your memory works.

EXPLORE Encounter an interesting word or phrase — in a show, a conversation, a book. AI explains it in plain language with examples at your level. Not a sterile dictionary entry — context you can actually learn from. Includes synonyms, phonetic transcription, transliteration, and word frequency ratings. Smart input validation catches typos and wrong-language entries, suggesting corrections so you always find what you need.

LEARN Save a card and AI fills it with examples at your level — learning starts right away. Organize cards into decks by topic. Search, filter, and track each card's learning state and next review time.

REVIEW Adaptive sessions that follow your memory. Every card gets its own schedule, updated after every review — not fixed intervals, real adaptation based on how well you actually know each item. Rate each card as Again, Hard, Good, or Easy, and the system adjusts accordingly. Every review brings a different example, a different context — building memory you can reach for in real conversation, not just on a flashcard.

ACTIVE RECALL Go beyond passive flashcards. Type the translation before revealing the answer — training your brain to retrieve, not just recognize. Fuzzy matching tolerates minor spelling mistakes. Get it right and the app confirms instantly. Get it wrong and the card's rating adjusts automatically, scheduling it sooner. Toggle on or off anytime.

LISTEN & PRONOUNCE Built-in text-to-speech at normal or adjustable slow speed. Fine-tune playback rates for careful listening.

LEARN YOUR WAY Create multiple language profiles — with or without translation, at your level. Set daily reminders to build a habit of regular review.

ADVANCED SETTINGS Take full control of the spaced repetition algorithm. Adjust desired retention and maximum review intervals. Apply settings globally or override them per card — so difficult words get reviewed more often while easy ones stay out of the way. Use synonyms as hints during review and control when they appear. Reset any card to its initial learning state for a fresh start.

LANGUAGES English, Spanish, Ukrainian, Russian — with more coming.

FREE TO START Core features are free. Upgrade to Pro for unlimited lookups, card creation, and storage — monthly or yearly.
