The Chessnut Air is one of the most popular electronic chess boards, a sensor board with on-board LED lights that recognises your moves and connects to online play, typically priced priced from ~$250 (official list is $249.99, and discounts are common). ChessGaze takes the opposite approach: it's a free app that turns the chess set you already own into a smart board using your phone's camera. Here's how they stack up.
| Feature | ChessGaze | Chessnut (Air) |
|---|---|---|
| Price | Free | from ~$250 |
| Hardware you need | Your phone | Dedicated sensor board |
| Use the chess set you already own | ✅ | ❌ (play on the Chessnut board) |
| How it reads the board | Phone camera + AI | In-board sensors |
| On-board LED move indication | ❌ | ✅ |
| Record moves & export PGN | ✅ | ✅ |
| Play against Stockfish | ✅ | ✅ |
| Live online play on the physical board | Records & exports after the game | ✅ live |
| Charging / batteries | None (just your phone) | Rechargeable board |
| Works with any set (wood, plastic, themed) | ✅ | ❌ |
Choose the Chessnut if you want the tactile feel of a dedicated board, on-board LED lights guiding moves, and seamless live online play against people directly from the physical board, and spending around $250 is fine.
Choose ChessGaze if you'd rather pay nothing, keep the board you already love, and still record every game, export PGN to Lichess or Chess.com, and play Stockfish, just by pointing your phone. It's the natural free alternative to a Chessnut board, especially for recording over-the-board games.
