Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for realtime. If latency matters more than voice catalog, start here.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.
