- [Somebody AI](https://somebodyai.co/): research, Embodied AI, live. The product is Somebody AI's: live AI avatar agents with a face and a voice that listen, answer, show and take action on websites, in training, in meetings and in stores, rendered live in the browser rather than streamed as video. AEI's role: applied research and engineering on improving Somebody's core avatar AI, focused on quality, performance and consistency for the next generation of its avatar fleet, at planet scale.
- Language mastery engine (EdTech): Cambridge B2 and C1 exam practice that forces recall instead of recognition.

Over 30,000 exercises across 82 topics. Two products:
  - [i-Speak English Practice](https://practice.englishclassesonline.co.uk/): B2C, live, in partnership with the i-Speak English brand. Free tier, €12.99/month.
