| Kai's verdict | A-tier for real-time. B-tier for everything else. Worth checking when news breaks. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier. If you're on Vercel/shadcn, this is cheating. | S-tier for academic research. Nothing else comes close for systematic reviews. |
