KyuAdvisor

Ask · Play

Ask about a game on the web, or sit down and play one against KataGo.

Same credits. The Chrome side panel is for kifu on sites you already use. Play is a full game in the browser: you take Black, KataGo takes White, then review. Not a subscription.

A real session

The page is the game. The panel is the coach.

A KataGo Training game on the left; KyuAdvisor on the right with the same position, win-rate bar, and three next-move candidates labelled A, B and C.
katagotraining.org · game 2047926 · KyuAdvisor 1.1.42

Left: a rating game on KataGo Training, move 175. Right: the KyuAdvisor side panel after “Sync page”. Same stones, same turn. The question was “Who is ahead, and by how many points?”

KataGo’s search said White was ahead, about 12.8 points, winning 84.4%. DeepSeek wrote that in a few sentences and marked the next three candidates: A M17, B B4, C K18. Click a letter to walk the variation. Arrow keys step the main line, same as the ◀ ▶ buttons.

A new question costs one credit. Asking the same thing again is free. Read the short note, or install the extension. To play a full game, go to Play.

Where it works

Open the Go page you already use

You stay on that website. The side panel either syncs the kifu, or captures one video frame. Site names are the same in every language.

Sync the record

Click “Sync page”. You get the moves and can step with ◀ ▶ or the arrow keys.
