Kai's verdictB-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.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
