Local Stockfish analysis saves after each move and resumes across restarts and app updates. Quick scans identify practice candidates; verify important positions with a deeper review. Results describe the games analysed so far.
Training settings
Separate positions run in parallel. Live analysis takes priority. Memory limits include room for engine processes and other applications.
Choose your colour for screen recordings; the app does not infer your identity from board orientation. Recordings without a known side are excluded until you choose White or Black. Correct the side for a recorded game below if needed. Imported PGNs use your username.
