Kai's verdictS-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.A-tier for sales teams. B-tier for solo users.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.
