Comparison
Audit Chess vs ChessDNA
ChessDNA positions itself as an AI coaching platform, offering style analysis, training plans and coached improvement paths. Audit Chess takes a different approach: it processes your actual game history - every blunder, every opening result, every blown win - directly in your browser, for free, with no account. ChessDNA curates an improvement plan; Audit Chess surfaces the exact data from your own games and lets you act on it. If you want a coached structure, ChessDNA has value. If you want to know precisely what is costing you points - ranked, evidenced, and turned into puzzles - that is what Audit Chess is built for.
The core difference: coached path vs raw data
ChessDNA provides AI-generated coaching: it observes your style and prescribes training. Audit Chess provides analysis: it reads your results and surfaces what the data shows. Both aim to improve your chess, but the approaches are fundamentally different - one guides you through a curriculum, the other tells you exactly which positions and openings to study based on where you have actually lost points.
For self-directed learners who want to work from their own results, Audit Chess is more direct. For players who want a structured programme with curated exercises, a coaching platform adds value.
Puzzles from your own blunders
Audit Chess builds Stockfish-verified puzzles from every blunder and missed tactic in your real game history. You drill the exact positions where your calculation failed, rather than a generic set matched to your rating. ChessDNA does not offer this - its puzzle recommendations are general rather than derived from your specific mistakes.
Cost and access
ChessDNA is a subscription service. Audit Chess is completely free, requires no account, and runs entirely in your browser - nothing is uploaded or stored. There is no free tier versus paid tier comparison to make: Audit Chess is entirely free.
