Reddit PGN Viewer is a free tool designed for chess enthusiasts who frequent the r/chess subreddit. This Firefox extension provides a seamless inline viewing experience for Portable Game Notation (PGN) files. By replacing traditional PGN text enclosed in [pgn][/pgn] tags, it presents users with an interactive chessboard that displays game variations, annotations, and comments, enhancing the way chess games are shared and discussed within the community.

The extension streamlines the process of analyzing chess games by allowing users to interact directly with the chessboard. This functionality not only aids in visualizing moves but also facilitates deeper engagement with the content shared in posts. With its user-friendly interface, Reddit PGN Viewer is a valuable addition for anyone looking to enhance their chess experience on Reddit.
