Kai's verdictA-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
