A fun, low-pressure way to practice speaking with AI characters you actually want to talk to.

[Demo]

Choose a topic, pick an AI character, and start speaking. Dori gives you instant feedback on your delivery and helps you find the right words for your thoughts, with characters that have real personalities, natural voices, and daily scenarios that make every session something to look forward to.

[Problem Statement]

The Problem

Adults learning English feel anxious about speaking. They want practice but lack the confidence to start, fear judgment, don't know what topics to discuss, and no convenient practice partners.

What I Learned

  • Design around AI's inconsistency. AI gives a different output every time. The key is knowing when that's a feature, when it's acceptable, and when it must be controlled. This shaped most of our product decisions.
  • When you don't have the best tech, craft the experience. We couldn't compete on model capability. But by combining existing tools creatively, a five person team built something users actually enjoyed.
  • In edtech, think about retention from day one. We helped users start speaking, but keeping them coming back is a different problem. If I could do it again, I would invest more time thinking about it.
