Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for open-source model APIs. The default in this space.A-tier. Best for cinematic image-to-video. Pair with Runway for coverage.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
