# Quizb AI vs AI教师助手

Both are free to download. Quizb AI sells 10 one-off in-app purchases and AI教师助手 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Quizb AI ships an update every 6 weeks, AI教师助手 every 3 weeks. The most recent releases landed on November 4, 2026 and October 27, 2026 respectively.
