Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.S-tier for model-shopping. I use this for every prototype before committing.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.
