What Kikashi does
Your games, not a textbook
Enter your OGS name. Kikashi finds the moves that cost you the most and builds your own practice cards from them.
Test first
Each card asks "what would you play?" before it explains anything. Trying first is what makes the answer stay.
Spaced repetition
Ideas come back after a day, three days, a week, three weeks. What you know fades away; what you forget returns sooner.
Explanations you can check
The words come from facts that are calculated and verified on the board, such as liberties, captures and whether a group lives, in plain English.
Honest progress
You see what you learned and whether your real games changed, with the uncertainty shown. Opening the app is not counted as getting stronger.
Evidence-based
The method (practise recall, space it out, learn from your own errors) is well supported by learning research. Whether Kikashi makes players stronger is something we are measuring, and we will say what we find, even if it is "not yet".
Who it is for
Adults who play real games, on OGS or at a club, somewhere between 25 kyu and 10 kyu, and who keep losing games to the same kinds of mistake. You know the rules. You want to know what to fix, and to see it fixed.
Complete beginners are welcome too, but Kikashi works best once you have games to learn from.
Fair play, privacy
- Kikashi only looks at finished games. It never helps with a game in progress.
- Your answers and scores stay on your phone; only your OGS name goes to OGS, to fetch your public games. No ads, no tracking, no account to make. This site uses no cookies.
- For people aged 16 and over. See the privacy policy.
Join the waiting list
We will email you once, when Kikashi opens to more people, and only about that. Leave whenever you like.
Your details go to our form service (named in the privacy policy) and nowhere else.
