ChessMazius is an all-in-one chess platform for players, coaches, teachers and tournament organizers, bringing analysis, training and community tools together in one workspace. Players can analyze games, positions, PGN files and engine lines with Stockfish, maintain a study library, build opening repertoires and prepare for opponents using FIDE profiles, game histories and opening tendencies. The platform also offers an openings explorer with ECO codes, master-game statistics and continuations.

For training, ChessMazius provides puzzles organized by themes such as forks, pins, skewers, mating patterns and endgame tactics, alongside visualization, memory, clock and survival exercises. Its community features help users find tournaments, players and coaches, including tournament searches by location, date and FIDE-rated status. Teachers can create classrooms, assign homework and track student progress, while organizers can manage tournaments. Additional tools include converting scoresheets, photos and PDFs into PGN, a board editor, interactive book reading and chess-related calculators and mini-games. ChessMazius is designed to support serious study, practical preparation and chess learning in one connected platform.
