One System
One System connects a small business's website to Claude. The owner installs the free One System CRM plugin on WordPress (or uses our developer kit for sites built with code), signs in, and asks Claude for changes in plain words: update opening hours or a phone number everywhere, rewrite a heading, write a blog post as a draft and publish it, add image alt text, fix Google titles and descriptions, edit menus or the site's llms.txt, and prepare social posts for the owner's approval. Claude asks before changing anything; One System records every change with the original value, who asked and from which app, and undo_change (or Undo in One System) restores it. One connection can cover several of the owner's businesses — Claude asks which one when a request doesn't say. The plugin only accepts a fixed list of edits: it never runs code, edits theme or plugin files, installs plugins or changes users and security settings.
