ChessLab: Openings & Puzzles

ChessLab is a complete chess trainer, a chess game, and — new — a reel studio that turns your games into videos. Study 10,000+ openings, solve 11,000+ puzzles, play Stockfish across 7 skill levels, and share your best move as a vertical video built for Reels, Shorts and TikTok. Works offline.

From your first move to grandmaster strategy — ad-free with Premium.

NEW: AI REEL STUDIO

Paste a PGN. The engine finds the moment worth watching and builds a vertical video around it.

• AI picks the key move and writes the title • Cinematic effects — pieces slam, the board reacts, the camera follows • Frame-by-frame camera control: your own zooms, shot lengths and cuts • Move call-outs (BRILLIANT, BLUNDER) in five text styles and three sizes • Any colour you like — presets or a full colour picker • Title and end cards you can restyle, resize or switch off • Lay your own music under it, and pick which part of the track to use • Move sounds mixed into the exported file • Build reels from your game, a famous game, or a puzzle
