Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier in its category. The first AI music tool I'd actually listen to.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.B-tier. Granola is better UX but Otter works everywhere. Pick based on your platform.
