The copy agent·AI tool

Nobody waits on me for a copy change anymore.

The problem

At Shifu I handled two live company websites. The copy changed often, sometimes weekly, because the positioning kept shifting.

One person owned the copywriting, so every change ran the same loop:

  • I designed and coded the section.
  • I took a screenshot and put it in Figma.
  • They left comments on it.
  • I fed each comment back one by one to update the copy.
  • They checked it live, asked for more changes, and it started again.
The old loop: a screenshot into Figma, a round of comments, then a prompt for each one.

There was one more problem. Copy that sounded right in their head might look wrong on the page, so they needed to see it live before approving. All of this cost me 5 to 6 good hours, and them 2 to 4. This was time meant for design strategy and bigger projects.

What I built

They could only judge copy once they saw it on the real site. So I built a tool that lets them do that without me in the middle.

You drop the agent into any website's codebase and it does two things:

  • It reads every piece of text and opens a private copy at its own link.
  • It logs each piece of copy against its exact place in the code.

The person opens that link, double clicks any text, and edits it right on the page. They try a few versions, see each one live, and choose. No screenshots, no Figma, no comment lists.

When they finish, I drop the log into the production codebase and every change goes live in minutes.

I kept all editing on the private link, never on the live site. Editing production directly risks bugs. This way they experiment on a safe copy, and the live site only receives one finished set of changes.

Results

The founder can now see the copy on the real website while writing it, instead of imagining it from a comment. That alone made the copy better.

A round that used to take most of a day now takes a short session, and both sides only spend time on the words. It works on any project, saving the same hours every time.

I don't do the same slow work over and over. Once I see the pattern, I build the tool that takes care of it.
