Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.B-tier. Useful for first drafts. v0 is the better bet for shipping code.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
