Show HN: Lathoa, a math app for kids where the AI is wrong on purpose
Summary
Lathoa is an educational math app for ages 10–14 that teaches kids to spot incorrect AI-generated reasoning rather than just compute the right answer. The app presents problems with intentionally flawed steps, requiring students to identify the bad step, explain why it’s wrong, and learn from a verified solution, while emphasizing safety and COPPA-compliant privacy. It offers free daily cases and tiered subscriptions for families, with problem verification to ensure safe AI usage.
