Show HN: Lathoa, a math app for kids where the AI is wrong on purpose
11 hours ago
- Errol is a math companion that intentionally makes mistakes in step-by-step solutions, teaching kids to detect errors and think critically.
- Kids engage in a detective-like process: scan steps, spot the wrong one, explain the mistake, and see the correct solution.
- Difficulty scales with three tiers (Obvious, Sneaky, Expert) to match age and skill, with ranks earned by catches.
- It emphasizes explaining errors in one's own words to build deep understanding, unlike typical answer-focused apps.
- The app includes features like replayable case files, emotion-based feedback, and no grading pressure.
- Privacy-first: no ads, no data harvesting, COPPA-compliant, with a free tier.
