Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.	A-tier. Best for teaching a kid to code in 2026.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
