Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
