Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier in its niche. The only one that actually gets emotion right.S-tier in its category. The first AI music tool I'd actually listen to.
