Kai's verdictS-tier for local inference. If you care about privacy or want to tinker, install this today.B-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. Genuinely different vibe from Suno — worth trying both for a month.
