Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for speed. When latency is the product, start here.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for academic research. Nothing else comes close for systematic reviews.
