Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. Market leader with reason. Start here for serious video.B-tier. Still early. Manus is more flexible for less money.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
