Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Still catching up on quality vs Kling/Runway Less control than pros need	Slight markup over direct API Some provider features not exposed	Pricey vs free Duolingo Conversation AI still stiff sometimes
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier if you already pay Gemini. B-tier standalone.	S-tier for model-shopping. I use this for every prototype before committing.	A-tier. If you already love Duolingo, worth it. If starting fresh, try ChatGPT Voice instead.
