The brief
The challenge.
Language learners need opportunities to practise conversations, not just complete fixed exercises. The experience also needs to fit their stage in the course.
The work
The approach.
Duolingo Max offers AI-powered Roleplay scenarios and Video Call conversations with Lily. Curriculum experts write Roleplay scenarios and opening messages, guide the model and review generated content. Learners can report inaccurate responses.

What this means for your project.
Design an assistant around a specific user task, not an open-ended chat box. Set the context, define useful feedback and give people a simple way to flag errors. Measure whether the experience helps them complete the task.
