Weaknesses	Output quality behind Claude for polish SEO automation can produce generic content	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control	Can feel overwhelming for non-coders Expensive at scale	Developer-only You build the UI
Kai's verdict	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.	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.
