Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
