| Kai's verdict | A-tier for the right use case. Not for solo devs. If you manage engineers, try one license. | A-tier for ops automation. B-tier for simple copy (use Claude). | A-tier for its niche. Different use case than Suno — SFX and loops, not songs. | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. |
