Weaknesses	Slight markup over direct API Some provider features not exposed	Output quality behind Claude for polish SEO automation can produce generic content	Less agentic than Cursor/Claude Code Model quality varies	Output needs designer polish Pricing unclear / changes often
Kai's verdict	S-tier for model-shopping. I use this for every prototype before committing.	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	B-tier. Useful for first drafts. v0 is the better bet for shipping code.
