I'm a founder of AI product, also is a big user of YM (actually our products have some similar features LMAO :)
For me, I used YM since ver0.1 until 0.4, TBH the experience is way better than my expect. As an AI-native writting studio, "save/create anywhere" is very straight forward for me. With its help, my chaotic docs( relevant to my creation) could be narrow down and schedule smoothly. cant wait for next version
