| Kai's verdict | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for aesthetics. If you care how it looks more than how it's made, this wins. | S-tier for academic research. Nothing else comes close for systematic reviews. | S-tier for realtime. If latency matters more than voice catalog, start here. |
