AI Sensei is a website created by Benjamin Teuber.
Games can be uploaded in SGF format, which the site can then analyze with the help of AI, and point out any mistakes that were played.
It comes as a free offering with premium subscriptions for higher quality.
AI Sensei uses recent versions of KataGo.
In 2021 the site added live AI analysis and a discussion feature that allows players to ask and answer questions about moves.
In 2022 the site added Play vs AI that allows users to play against a 50 playout Katago on 9x9, 13x13, or 19x19 boards with up to 9 handicap stones and custom Komi from 10 to -10.
