SGF and variation trees
Import games while preserving branch structure, then promote, remove, and return to variations without flattening your study.
Local AI review workspace for Go
Study every move with KataGo on your own machine.
TensuGo is a desktop review app for Go players. It imports SGF files, runs local KataGo analysis, shows candidate moves, win rate, score lead, visits, and principal variations, then helps you turn variations into study notes.
Windows x64 includes the built-in KataGo OpenCL engine. macOS Apple Silicon requires KataGo installed separately.
Why It Exists
Not a live score widget. A real study desk for reviewing games.
Serious review often means switching between a board, an AI engine, an SGF editor, and scattered notes. TensuGo brings those pieces into a quiet desktop interface where you can follow the game tree, inspect candidate lines, keep meaningful branches, and preserve the reasoning behind them.
Features
Built around review, not around engine knobs.
Local KataGo analysis
Run KataGo locally and inspect candidate moves, win rate, score lead, visits, and PV without uploading your games.
Candidates and trends
Candidate bubbles, move tables, and win-rate trends stay in sync so you can spot turning points and direction mistakes quickly.
Research notes
Collect board diagrams, candidate lines, and written commentary into review material for study, teaching, and archiving.

From one game to a readable review.
