Vocabulary In Context. Measurable Progress.
Transform isolated flashcard study into engaging, personalized reading experiences backed by spaced repetition, helping you to gain fluency, enjoyably.

Here's how Mosaic works
Mosaic constructs natural language passages that are exactly tuned to your language level by modeling your vocabulary. When you review a passage in Mosaic Reader, you get credit for having seen all the words in the passage.

The core Mosaic workflow
Instead of reviewing each vocabulary card individually, read natural language that integrates them all.
Review Your Vocabulary in the Context of Natural Language
See your vocabulary in real-world usage. No more isolated flashcards: experience your study words in authentic contexts, meaningful stories, and natural language patterns.
This deeper context helps you understand not just what words mean, but how they're actually used.


Review more words in less time
Mosaic dramatically reduces review time by allowing you to practice multiple vocabulary word in a single coherent passage. What might take 30 minutes of isolated flashcard reviews can be accomplished in 10 minutes of engaging reading.
This efficiency doesn't just save time—it improves retention by presenting words in meaningful relationships rather than isolation.
Stay Engaged with Reading Passages Personalized to You and Your Interests
Choose your own learning adventure with personalized content themes. Whether you're interested in business, travel, technology, culture, or any other topic, Mosaic generates reading material aligned with your personal interests.
This customization keeps you motivated and engaged, making language learning feel less like study and more like exploration of topics you genuinely enjoy. You can even provide specific prompts or themes to tailor content precisely to your current interests or learning goals.


Seamless Learning Tools at Your Fingertips
Mosaic integrates powerful learning tools directly into your reading experience. Look up unfamiliar words with the one-click dictionary, view passage translations, and add new words to your Anki collection, dive into questions with the chat assistant, and all without leaving your reading flow.
These seamless supports remove friction from the learning process, allowing you to maintain momentum while still addressing challenges as they arise.
