Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
