Context
Rivière Yuan, an EdTech company working between France and China, wanted a platform to learn Chinese in middle and high school: lessons that teachers adapt to their classes, and students who each progress at their own pace.
Approach
We owned the product and the code: students' and teachers' needs, learning paths, MVP scoping, then development of the complete application. Generative AI helps teachers create their content and personalizes the learning paths; speech recognition assesses pronunciation.
Deliverables
- Lessons and teaching content created by teachers, assisted by generative AI
- Homework: creation, submission and grading
- Speech recognition and pronunciation assessment
- Progress adapted to each student's level
- Chatbot, image generation, cultural context
