Weaknesses	Less agentic than Cursor/Claude Code Model quality varies	Developer-only You build the UI	Google-only Can be slow on large corpora	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control
Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	S-tier for builders. The right primitives. What Kai is built on under the hood.	S-tier for study. The Audio Overview is a killer feature. Try it with three of your favorite PDFs.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
