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.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.A-tier in its niche. The only one that actually gets emotion right.
