Two new Deer apps are in development
Deer Tutor's AI learning framework is expanding into multilingual learning and cross-disciplinary transfer.
Deer Language
Deer Language is a Deer Tutor spin-off built for multilingual learning. It uses the same AI framework and supports French, Spanish, German, Japanese, and more, helping learners practice through context, questions, and review.
Deer Learner
Deer Learner is designed for the AI era's cross-disciplinary learning needs. It draws on Socratic questioning and the Feynman technique to turn complex domains into explainable, question-driven, reviewable learning paths.
