Blundr does the opposite — it watches you play, finds the patterns where you lose ELO, and feeds you exactly the position-shapes you need to drill. The AI coach is grounded in your actual games, not a generic curriculum. GROWN-UP MODERATION Chat is opt-in and consent-gated. Every chat surface has a Report button that goes straight to a human moderation queue. Repeat offenders get muted or removed. QUESTIONS / FEEDBACK We read every email at support@blundr.co. Pull-to-refresh on the dashboard is the fastest way to recover from a flaky connection.
