Kai's verdictS-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 academic research. Nothing else comes close for systematic reviews.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
