| Kai's verdict | A-tier in its niche. The only one that actually gets emotion right. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier if you already pay Gemini. B-tier standalone. | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. |
