One scan tells you more about your chess than a year of game review. Free tier, no card. Upgrade when you want the engine to go deeper.
Pro is $5/mo instead of $8/mo right now, and early adopters keep that rate forever. Or skip the subscription entirely — Lifetime is $59, once.
When launch ends, new subscribers pay full price. You won't.
Find the leaks. All of them.
For players serious about climbing.
Early adopters keep this rate forever
Pay once. Never think about it again.
Chess.com badges a move "brilliant" one game at a time. FireChess reads your entire history and surfaces every real sacrifice — the moves where you gave up material on purpose and the engine agrees it was correct. Your best moments, collected in one place.

Comparison based on Aimchess free tier as of March 2026.
FireChess is built by one person — a ~2200 rapid player on Lichess who got tired of tools that grade one game at a time and never tell you what to actually fix. No VC, no growth team, no roadmap committee. Just me, Stockfish, and a lot of late nights.
Your $5 (or $59, once) pays for servers and engine time — and buys me more hours to build. When something's broken, I usually ship the fix the same day. That's the whole business model.

What's actively being built — no vaporware, no "coming soon™" from two years ago.
Compare your reports week-over-week. See if your leak count, accuracy, and radar scores are improving with trend charts on your dashboard.
Better AI-generated explanations for why the engine's move is better — with plans, threats, and positional concepts instead of just engine lines.
Upload PGN files directly instead of fetching from Lichess/Chess.com. Export your analysis as annotated PGN to study in other tools.
Auto-generate a repertoire from your actual games. See which lines you play, where you deviate, and suggested improvements.
Save positions into study sets. Practice them with spaced repetition so you actually remember the correct moves.
Multi-student management for coaches. Share reports, assign homework positions, and track student progress.
Free scan. 300 games. Two minutes. No credit card.
