OpenWords - Learn Words

Stop forgetting new words. Look up words, create cards in one tap, and master them with multi-format learning modes. Free, no ads, and no accounts.

OpenWords helps you actually remember the words you look up. It is a deep-dive dictionary and vocabulary tool built for learners who want to truly master English, Dutch, Polish, or Russian. Most apps show you a translation and then you forget it. OpenWords is built to turn those lookups into long-term knowledge. The app provides translation support for English, Dutch, German, Spanish, French, Italian, Turkish, Russian, Polish, Czech and Simplified Chinese.

DICTIONARY WITH CONTEXT

• Multi-sense lookup: Don't just get a translation. See every meaning and save only the specific sense that fits your current context.
• CEFR levels & frequency: Know if a word is A1 or B2. See if it's high-frequency daily speech or niche vocabulary so you can prioritize your learning.
• Word families: View related roots and forms to understand patterns and grow your vocabulary faster.
• Examples & phrases: See how words actually function in real sentences.
