Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.
