AI Sensei
AI Sensei is an AI-assisted Go learning platform that makes game review easy. Powered by KataGo, it analyzes your games with focus on the biggest mistakes first, while letting you explore any position in depth with built-in live analysis. No downloads or powerful hardware needed; everything runs in your browser or mobile. With a free tier and premium plans starting at $5.95/month, strong AI analysis is accessible to every player.
Beyond analysis, AI Sensei offers humanlike AI opponents from 30 kyu to 9 dan. These are bots specifically trained to play like humans at each level, not just a weakened superhuman AI. Training Mode lets you save critical positions from your reviews and practice them until they stick, turning real mistakes into lasting improvement.
