Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs.
