| Kai's verdict | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week. | A-tier if you already pay Gemini. B-tier standalone. | A-tier. Niche but beloved. If you've outgrown Notion, try this. |
