AimChess is a chess improvement platform that connects to your Lichess or Chess.com account, analyzes your game history, and uses the patterns it finds to build a personalized training plan. Rather than offering generic puzzles, it identifies the specific weaknesses in your play — particular opening lines where you frequently go wrong, tactical patterns you miss, endgame types you mishandle — and targets training at those areas.

The platform provides insights into your playing style and trends over time: how your accuracy changes as games go long, your performance under time pressure, your results with specific openings, and more. The "Roadmap" feature creates a structured weekly improvement plan based on the analysis.

AimChess offers a limited free tier; full access to training plans and detailed insights requires a subscription. It is available on web, iOS, and Android. The personalized approach makes it particularly effective for self-directed improvers who want data-driven guidance rather than a pre-set curriculum.
