| 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. Beautiful UX. The writing app I'd pick if I only wrote long-form. | A-tier. The strongest 'no-code' AI builder right now. Great for founder MVPs. |
