Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier in its niche. The only one that actually gets emotion right.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier. S-tier if you self-host. The reason open-source image gen matters.
