Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
