Kai's verdictB-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.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
