Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier in its category. The first AI music tool I'd actually listen to.
