| Kai's verdict | S-tier for academic research. Nothing else comes close for systematic reviews. | S-tier for builders. The right primitives. What Kai is built on under the hood. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. |
