import_jmr · x · 2026-08-06
The author shares the success of the AI education product Rori. Running on cheap phones via WhatsApp, it uses ability-based placement, hallucination constraints, and real-world scenario design. In an RCT, it helped students improve math scores by 0.36 SD (equivalent to a year's growth).
Core design principles:
- Teach at the right level: Matches exact student ability with instant feedback.
- Low barrier to entry: No app installation needed; works directly via WhatsApp text.
- Fenced model: Uses over 500 expert-written lessons to constrain the model, preventing incorrect outputs.
