1. New-generation KataGo on your phone
GoKifu AI is the world's first smartphone app to feature the new-generation KataGo model. KataGo is included in your regular subscription, with no additional fee.
It makes full use of your phone's performance to show the best moves, variations and win rates in real time.
AI analysis also works offline, including on flights or anywhere without a signal. An internet connection is required once every three days to verify your subscription.
2. Playing strength assessment and Shusaku AI coaching
Import your own game records to estimate your playing strength from 7 Kyu to 9 Dan. Use the results as a guide to track your progress.
Assessment requires iOS or iPadOS 16 or later. It takes longer on devices with A13 or older chips, including iPhone 11.
During a game, our own Shusaku AI, trained on Honinbo Shusaku's game records, offers advice as your coach. Enjoy the feeling of having a legendary Go master by your side.
3. Board Scan: from photo to analysis
Scan a position from a screenshot shared from a Go site, a photo in your library or your camera.
Start AI analysis without entering the stones by hand. It's also a convenient way to review games after you play.
Supports 19×19, 13×13 and 9×9 boards.
4. Learn joseki from professional games
Set up a shape on the board to search for matching positions in games played by leading professionals, including online games.
Search joseki and opening patterns, reverse Black and White, or filter by player name or username.
5. Play across the eras of Go
Experience the solid style of Honinbo Shusaku or the creativity of Go Seigen through AIs trained on their game records.
Play against AIs from different eras to explore the styles of past and present masters. You can also watch matches between eras, such as Shusaku's era versus modern Go.
6. Flexible editing and cloud backup
Insert or delete moves in the middle of a game record to correct input mistakes. There's no need to delete and re-enter dozens of later moves.
Transfer records to Google Drive or iCloud Drive. Google Drive also supports automatic transfer to help keep your records safe.
Open SGF, UGI, NGF and UGF files, including formats used by GoQuest, the Nihon Ki-in's Yugen no Ma and Pandanet, and convert them to SGF.
7. A built-in browser for game records
Browse external game-record sites without leaving the app. SGF data on the page is detected automatically, so you can start AI analysis right away.
