Chessis: Advanced Chess Analysis for Strategic Improvement

Chessis is a powerful mobile chess analysis application designed for players seeking to deeply understand and improve their game. It moves beyond simple move validation, offering a forensic-level examination of your play using the robust Stockfish engine. By uploading games from platforms like chess.com or Lichess, users of Chessis receive a detailed breakdown of performance, identifying critical errors and revealing hidden opportunities. This makes Chessis an indispensable tool for any serious player committed to strategic growth.

Detailed Game Report Generation

Players start by importing a game via PGN file. Chessis then processes every move, comparing player decisions against engine-recommended lines.  Chessislication generates a comprehensive report that categorizes each move, highlighting blunders, mistakes, and missed wins with precise centipawn loss data. This progression through your game history provides a clear, quantifiable measure of performance, turning each analyzed game into a personalized lesson plan. The reward is a structured understanding of your weaknesses.

Interactive Board Analysis with Threat Visualization

Within Chessis, users can tap on any position from their game to enter analysis mode. Here, they can explore alternative moves. The key feature is the threat display; with a toggle, all of the opponent’s immediate threats materialize as red highlights on the board. This interaction allows a player to visually understand why a move was weak and what dangers were overlooked, directly linking a abstract evaluation to a concrete, visual lesson that impacts future gameplay decisions.

Customizable Engine Interrogation

For deep dives, Chessis allows users to modify the analysis engine's parameters. You can adjust the thinking time, depth, hash size, and thread count to prioritize speed or extreme accuracy. This means for a critical endgame position, you can set Chessis to a deep analysis mode, commanding the engine to calculate for several minutes to uncover resources many moves ahead. This powerful customization ensures the analysis is tailored to the complexity of the position being studied.

Opening Explorer and Database Integration

Chessis includes a searchable database of chess openings. Players can input a board position or use the integrated board editor to set up a specific opening formation. Chessis will then display the opening name, main lines, and common transpositions. This function is used to study new openings or understand the theoretical standing of a position reached in your own games, helping to build a stronger repertoire and identify early-game inaccuracies.

Play and Learn Against Adaptive AI

Beyond analysis, Chessis functions as a training partner. You can start a new game against the computer, setting its strength to match your skill level. During  Chessis, you can enable move strength indicators and real-time blunder alerts. This live feedback loop helps reinforce good habits; if you make a questionable move, Chessis can immediately flag it, allowing you to take back the move and try a better option, thereby learning through direct interaction.

Position Editor for Scenario Training

The board editor in Chessis lets users create any custom position. This is ideal for practicing endgame techniques or testing specific tactical ideas. You can set up a king and pawn versus king endgame, for instance, and then use the engine to play out both sides. This hands-on manipulation of pieces to create and solve problems offers a sandbox environment for targeted, deliberate practice that directly improves your tactical vision.

Exporting Annotated PGN Files

After analysis, Chessis enables you to export your entire game as an annotated PGN file.  Chessislication saves all its comments, arrows, and evaluation lines directly into the file. You can then share this richly documented PGN with a coach, study it on a computer, or archive it for later review. This workflow creates a permanent, portable record of your analysis session, extending the utility of Chessis beyond the mobile app itself.
