News/info A Go app that's big in Japan (pros use it too): offline KataGo + camera board scanning — free month for the Go Congress
Hi r/gogame 👋
I'm the developer of GoKifu AI (囲碁レコAI), a Go study app for iPhone/iPad. It's become pretty popular with players in Japan — even some pros use it — and I've just opened it up worldwide, so I wanted to share it here (and bring a free month for everyone heading to the Go Congress).
🧠 Fast KataGo Analysis:
Full KataGo runs on-device — no server, no internet. Win-rate, score estimate, best moves, and variations, all offline. Perfect for planes, tournaments, or bad Wi-Fi.
📸 Scan a real board with your camera
Point your phone at a physical goban and it reads the whole position instantly — then analyze it, save it, or replay it. This is the feature people love most. (short demo below 👇)
A few other things it does:
- Joseki & fuseki search (learn from 170,000+ pro games)
- Play against legendary Go AIs — Shusaku, Sai, and more.
- Win-rate timeline to see exactly where the game turned
- Mistake finder that flags your biggest slips
- SGF import/export & kifu recording

A note on availability 🙏
Not on Android or in the EU yet — Android is in active development, and I'm still sorting out the EU's publishing rules (they'd expose my home address, so I'm holding off for now). Please hang in there — it's coming, and I think you'll really like it!
Thanks for taking a look! 🙏
