Speaking practice that doesn’t wait for class.
In a class of thirty, speaking time runs out fast. Katasaga gives every learner a live conversation partner inside a story, with the menus, maps, messages and articles they’d use in real life.
For parentsStrong guardrails on every conversation.
- A safety check runs alongside every live conversation
- Harmful, sexual or hateful content ends the session straight away
- Characters can’t be talked out of their role or their rules
- Every story and character is written by our team
- Voice is never stored as audio, and there are no ads or trackers
For teachersSpeaking time for every student, in six languages.
- Live conversations with story characters, in six languages
- Real-world material to use mid-conversation: menus, maps, messages, articles

Talks their way through each scene, using what the scene hands them.
