Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier. Market leader with reason. Start here for serious video.S-tier for builders. The right primitives. What Kai is built on under the hood.
