A silent Chess.com game recorder with private, post-game Stockfish reviews. Aftermove is a silent Chess.com companion that privately records your games and opens an instant, post-game engine review powered by Stockfish running directly on your computer. KEY FEATURES • Automatic Game Detection: Aftermove observes your game on Chess.com without any noisy overlays or popups during live play. The moment your game concludes, it detects the result and prepares your review. • 100% Local Stockfish Review: Your moves never leave your device. Stockfish WebAssembly analyzes every position locally with zero subscription fees. • Best Move Arrows & Continuation Sequences: Whenever a suboptimal move is played (from an inaccuracy to a blunder), Aftermove automatically displays the best engine alternative on the board, along with an interactive 3-move preview sequence showing how the game would have unfolded. • Player Accuracies & Side-by-Side Breakdown: View White vs. Black accuracy percentages (CAPS) and an intuitive side-by-side move quality breakdown comparing Brilliant, Great, Best, Good, Inaccuracies, Mistakes, and Blunders. • Quick Mistake Navigation: Use on-screen jump buttons or Shift + Arrow keys to navigate directly between blunders and mistakes. • Interactive Freeplay Analysis: Test alternate moves from any board state to see how Stockfish evaluates your ideas. • Multi-Worker Parallel Engine: Leverages your CPU's multi-core architecture to analyze games 2.5x to 4x faster. • Optional AI Coach: Connect your OpenAI or Google Gemini API key to ask natural-language questions about your completed games. FAIR PLAY & PRIVACY FIRST Aftermove is strictly a post-game learning tool. Engine calculations are hard-locked during live games and no live hints or evaluation bars are ever displayed while a match is ongoing. Your games and preferences stay private in your browser.
