“Just the other day, I used Vercel's v0 to build a small business website for a relative in 10 minutes.”
Spotted: found in the wild. Details are as reported by the source above and have not been independently verified.
What they did
Used Vercel’s v0 to build a small business website for a relative. Fed the site to ChatGPT 5.1 and asked it to improve the marketing text, then fed those improvements back to v0.
How it went
The first version took 10 minutes and looked fantastic and mobile friendly. The whole thing was finished in 15 minutes. Designing it, coding it, testing it on desktop and mobile and writing the copy would once have taken them at least one week.
