Kai's verdictA-tier. Niche but beloved. If you've outgrown Notion, try this.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
