- Camera input removes the transcription friction that makes typed maths input painful
- Worked steps rather than answers alone, which is what makes learning from it possible
- Maths and physics are the right domain, because the answer can be independently verified
- No AI model or provider is named, so there is no way to assess what produces the working
- No accuracy or reliability data is published for the solutions
- The homework-help framing never addresses the academic-integrity question it raises
