Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.B-tier. Still early. Manus is more flexible for less money.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
