| Kai's verdict | S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. | S-tier for academic research. Nothing else comes close for systematic reviews. |
