Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
