Best forDevelopers. Non-developers who want to ship working code.Game developers, podcasters needing SFX, video creators needing background music.Developers who want an agent, not autocomplete. Large refactors, tests, docs.Teams with GitHub already. Devs who don't want to change IDEs.

Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
