Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.A-tier. Niche but beloved. If you've outgrown Notion, try this.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
