Update all 12 pages of my website in three minutes

Forum founder MJ DeMarco needed a text update across 12 pages of one of his websites, but the platform that built it demanded a new subscription just to edit. He gave the AI access to the site folder instead; it made all the changes in about 3 minutes, avoiding an estimated hour of manual editing and a $20/month subscription.

Why it’s worth knowing

A three-minute folder task replaced both a developer chore and a $20/month platform subscription.
