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 infrastructure. The one platform every AI dev eventually uses.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.
