Wordrio: Vocabulary Builder

Stop forgetting the words you look up.

Wordrio turns every new word into one you'll actually remember. Save a word and AI instantly fills in a clear, easy-to-understand definition, a real example sentence, pronunciation, synonyms, the CEFR level, and a memory hint — so you don't have to type it all yourself.

Then Wordrio helps you make it stick:


Write your own sentences and get instant AI feedback on how you used the word
Smart spaced-repetition practice resurfaces words right before you'd forget them
A daily word game and flip-card flashcards make review fun
XP, levels, streaks, and daily quests keep you coming back
Gentle daily reminders surface your words as quick flashcards
Progress tracking shows what you've mastered and what still needs work
Your words sync across your devices


WHY IT WORKS
Most vocabulary apps stop at the definition. Wordrio is built around remembering: simple AI explanations, your own example sentences, spaced repetition, and playful review — the things that actually move a word into long-term memory.

WHO IT'S FOR
English learners, students, IELTS and TOEFL prep, avid readers and writers, and anyone who wants a richer vocabulary.

Wordrio is free to use, with more features on the way.
