Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. HeyGen wins for creators, Synthesia wins for enterprise.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier infrastructure. The one platform every AI dev eventually uses.
