Visual capture - Click the extension icon, drag to select any area of the page, and GoShawk will snapshot it instantly.
SGF/HEN conversion - The captured image is passed to a built-in converter that reconstructs the board position as an SGF or HEN file.
Copy to clipboard - Copy the SGF or HEN string to your clipboard.
Export as PIC+HEN - Export as a PNG or GIF with embedded position metadata.
No upload needed - Everything runs locally in the browser; no image is ever sent to an external server.
