PurePGN: Chess Game Viewer

Calculate clearly.

PurePGN is the minimalist, distraction-free environment built for pure chess analysis. No evaluation bars. No blinking engine alerts. Just you, the board, and your thoughts. Designed specifically for club players, tournament competitors, and serious hobbyists, PurePGN is the blank canvas you need to study deeply.

Core Features:

Fluid Notation Wrap: Read complex lines easily. The notation area adapts as you build deep variation trees, visually separating lines to ensure that calculating multiple branches remains perfectly readable without losing your main idea.

Instant Local Library: Never lose a crucial line again. Save your opening repertoire and analyzed games directly to your device with a lightning-fast, offline database. Search by player or event and load positions in milliseconds.

Seamless Workflow: Instantly paste games from your clipboard to review them. When you are done, export actual .pgn and .fen files right to your native share sheet to collaborate with study partners or move to other tools.

ECO Code Recognition: Automatically detect and display standard Encyclopedia of Chess Openings (ECO) codes so you always know exactly what structure is on the board.

Engine-Free Zone: Reclaim your focus. PurePGN strips away the noise so you can calculate like a human.

Designed for depth, not speed.
The best tools get out of your way. PurePGN was built specifically to capture fleeting ideas and analyze positions deeply without the constant, distracting hum of an engine telling you what to think.

Paste, analyze, save, and improve.
