Kai's verdictS-tier for open-source model APIs. The default in this space.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier in its category. The first AI music tool I'd actually listen to.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
