Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.B-tier. Still early. Manus is more flexible for less money.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
