CaptureGo converts photographed Go positions into analyzable digital boards
CaptureGo captures a Go board from a photo, TV frame, or screen and turns that static position into an interactive board for analysis and play. Made by 도나레 for Android, the app combines image recognition, manual editing tools, and an integrated AI to let players test continuations and save records in SGF format. It suits study-focused players who want to digitize physical or broadcast positions for immediate AI-assisted review and further study.
It digitizes board state directly from images
CaptureGo uses image recognition to detect boards and stones from camera photos or gallery images, and it supports 9x9, 13x13, and 19x19 sizes. The capture flow asks users to align the four outer intersections to improve detection accuracy, and the app offers high-precision alignment tools to correct angled photos. This lets players avoid manual entry when converting printed records, TV broadcasts, or physical games into a digital grid.
It supports study by letting you analyze and continue play from positions
The app includes an integrated AI that can analyse a captured position and continue the game from that moment, enabling situational testing of variations. Users can play both sides against the engine or run the AI analysis to examine candidate moves; captured positions can also be exported and imported as SGF files for use with other Go software, which preserves study workflows across tools.
It fits self-directed study and adaptable editing for accuracy
CaptureGo offers manual editing to add, erase, or adjust stones after detection, which helps when automatic recognition misses pieces. Multi-language support (English, Korean, Japanese, Traditional Chinese) means learners in different regions can use the interface, and the SGF import/export lets teachers or study groups share records. The app requires a functioning camera to use the capture feature, which defines how learners prepare material for review.
Effective for players who study game records, with a camera-dependent workflow
CaptureGo is a useful tool for Go players who want fast digitization and on-the-spot AI analysis of physical or broadcast positions; its alignment step and manual edit tools address imperfect captures but make the workflow camera-dependent. Players who study recorded games and share SGF files will find the app convenient for investigating local positions and exchanging records with other analysis tools.
