Why AI changes the wrong thing — and how to make it fix only what you mean
You asked your AI to fix one button. It fixed it — and quietly changed another one you never mentioned.
That's not the AI being dumb. It's you and the AI talking about different things. "The Order now button" can mean two buttons on the same page, and the AI has no way to know which one you're looking at.

What we actually tested
Same small coffee-shop site. Same model. Ten separate runs.
| Prompt | Header button | Hero button | Other buttons | |
|---|---|---|---|---|
| 5 runs | "Make the Order now button stand out more. Bigger, bolder, stronger color." | changed in 5 of 5 (not wanted) | changed | untouched |
| 5 runs | A note pinned on the exact hero button | changed in 0 of 5 | changed | untouched |
The AI didn't break the site. It just guessed — and the guess included a button you didn't ask about. On a real project that's the "fixed one thing, broke another" loop everyone complains about.
The fix: point, don't describe
Instead of describing where in words, point at the element:
- Open your page in the browser.
- Click + Add note, then click the exact thing you want changed.
- Write what should change: "Bigger, bolder, stronger color. Only this button."
- Your AI reads the note — with the element's selector, its HTML and a screenshot — and edits only that.
No more "no, the other button", no screenshots pasted into chat, no paragraphs explaining which card you mean.
Works with your own AI
The note tool runs on your computer and works on any page you can open in a browser: a plain HTML file, your local dev server, a React or Vue app. Your AI agent reads the notes through MCP — Claude Code, Cursor, VS Code and other MCP-capable agents.
It's Windows only for now and it's an early build: Windows may show "Windows protected your PC" because the installer isn't code-signed yet. Click More info → Run anyway. It installs without admin rights and keeps your notes in a local folder.
How to get it
The note tool comes free with the guide below. The guide shows how to set up the rest of your AI assistant: a rules file it reads every time, memory notes, helpers and a morning brief. The note tool takes care of fixes on your pages.
