Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Expensive Best for well-scoped tasks Not for solo hobbyists	K-12 focus (not deep for adults) Slower than general chatbots	Less feature-rich than Google Docs AI ceiling below dedicated tools
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.	S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.	A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.
