Any language should be learnable
Large language models make it possible to build language-learning experiences for any language pair, including languages that major apps have ignored.
AI-native tools
Tools for learning, life, and growth.

Steady momentum
The best products help people keep showing up, whether they are learning, practicing, reflecting, or building a habit.

From the blog
Early notes on learning, communication, and building with AI.
AI unlocks more natural ways to learn
The last generation of apps was shaped by hand-authored content and formulaic exercises. AI opens the door to conversation, exploration, and instruction tailored to the learner.
Building at the speed of inspiration
AI gives a single builder far more leverage, making it possible to move faster while still paying close attention to craft and detail.
