Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.A-tier for real-time. B-tier for everything else. Worth checking when news breaks.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
