Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
