Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for model-shopping. I use this for every prototype before committing.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
