Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for conversation. A-tier for TTS. Complement to ElevenLabs, not replacement.
