Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
