Build a shadow bot from a real player's habits.
Index real game pools, trim the sample to recent form or long-term tendencies, then practice against a bot that feels like the opponent you expect to face in real life.
Prepare for real-life opponents with a sparring partner built from their actual habits.
Shadow Bot Studio indexes real game pools, lets you tighten the window to recent form or widen it to long-term habits, then gives you a practical way to rehearse before you face that player over the board.
Point it at a player
Use a Lichess username, a Chess.com username, or combine both into one opening profile.
Trim the sample
Preview recent versus all-time history, keep only the speeds you care about, and watch the usable pool update.
Play the result
Save multiple bot profiles, launch dedicated arenas, and rematch the same shadow with a tighter plan.
Open the full Shadow Bot Studio.
The public sections above explain the product. The full builder opens on its own page, with room to load player history, preview ranges, and manage saved bots.
