Play, learn, and improve with an AI coach that watches every move and tells you what you missed — grounded in real Stockfish analysis, not vibes. WHAT'S INSIDE • Play vs AI bots tuned from beginner-friendly (≈400 ELO) all the way up to grandmaster strength. • Ranked play against real opponents with ELO-based matchmaking after a 5-game calibration window. • Friends — search by username, send game challenges, see who's online. • In-game chat (consent-gated, with one-tap reporting). • Tactics — hundreds of curated puzzles by theme and difficulty, with retry support. • Practice drills — middlegame plans, endgame technique, opening continuations. Free for everyone. • Opening explorer — full move-by-move PGN replay for the most-played lines. • Post-game AI review — engine analysis, blunder detection, and an annotated game story (3 free per month). BLUNDR PRO For serious improvers, Pro unlocks: • Unlimited AI Coach chat with grounded game context. • Unlimited post-game AI reviews and engine analysis. • Live coaching after every practice drill and opening line — your AI coach narrates every move you make against the engine. • Climb — a personalised training roadmap that targets your weaknesses with daily tactics, opening drills, and ladder game goals. • Date Mode — discover compatible chess players, send invitations, play move-by-move date games. Pro is purchased on the web at blundr.co/pricing and powers your account across both web and iOS. Cancel any time. WHY BLUNDR Most chess apps drown you in courses. 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.
