SHAPE is a Go app with AI feedback, designed to help you identify and correct common mistakes based on your skill level.
Run the application directly using uvx:
uvx goshapeThe first time you run this, uv will automatically download the package, create a virtual environment, and install all dependencies.
When the application starts for the first time, it will also check for the required KataGo models in ~/.katrain/. If they are not found, a dialog will appear to guide you through downloading them.
- Personalized Mistake Analysis: The AI feedback is tailored to your rank, flagging mistakes that are relevant to your level.
- Interactive Board: A clean, responsive Go board with heatmap visualizations.
- Detailed AI Feedback: An analysis tab shows the score graph and KataGo's top move considerations.
- Configurable Opponent: Play against an AI opponent with customizable rank, style, and behavior.
- SGF Support: Save and load games, or copy/paste SGF data from the clipboard.
The main window is divided into the board on the left and a control panel with three tabs on the right.
Underneath the board, you will find the main game controls:
- Pass: Pass your turn.
- Undo: Go back one move. This button is only active when there are moves to undo.
- Redo: Go forward one move. This button is only active when you have undone moves.
- AI Move: Force the AI to make a move, even if it is your turn.
This is the main control center for your game.
- Game Control:
- Play as: Choose to play as Black or White.
- Opponent Controls: Force the AI to move or enable Auto-play for the AI to play automatically when it's its turn.
- Player Settings:
- Current Rank: Your current Go skill level. This is used to determine which mistakes are typical for you.
- Target Rank: The skill level you want to aim for. Mistakes common at this level won't be flagged.
- Opponent: The type and level of the AI opponent. This supports modern, pre-AlphaGo style, and historical professional styles.
- Heatmap: Visualize the AI's preferred moves for different player models (Current Rank, Target Rank, AI, and Opponent). You can select multiple heatmaps to get a blended view.
- Info Panel: A collapsible panel (shortcut:
Ctrl+0) that shows detailed statistics about the last move.
This tab provides feedback from the AI.
- Score Graph: A graph showing the score progression over the course of the game. The Y-axis is centered at 0, with a dashed line indicating an even game.
- Top Moves: A table showing KataGo's top 5 recommended moves for the current position, including win rate, score lead, and visits.
- Deeper AI Analysis: A button to request a much deeper analysis (more visits) for the current position.
This tab allows you to fine-tune the AI's behavior.
- Policy Sampling: These settings affect the AI's move selection and the heatmap visualization. Tooltips are provided in the app for detailed explanations.
- Top K: Considers only the top K moves.
- Top P: Considers moves from the smallest set whose cumulative probability exceeds P.
- Min P: Considers only moves with a probability of at least P times the probability of the best move.
- Analysis Settings:
- Visits: The number of playouts the AI will perform for its analysis. Higher values lead to stronger play but require more processing time.
- Mistake Feedback: These settings determine when the game will automatically halt. The game halts if the mistake size is above the configured threshold AND either of the probability conditions are met.
Keep in mind that the techniques used are more likely to be helpful up to low-dan levels, and may not be as effective at high-dan or professional levels.
