Strengths	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Tab completion feels like mind-reading Composer for multi-file edits Runs Claude, GPT, Gemini — you pick	Production-grade agent primitives Built on Claude (best reasoning) Full control — build exactly what you need	Excellent prompt understanding Built into ChatGPT — no extra subscription Good at composition + concepts
Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Can feel overwhelming for non-coders Expensive at scale	Developer-only You build the UI	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control
Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	S-tier for builders. The right primitives. What Kai is built on under the hood.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
