Move a Chrome extension into Safari

A developer had ChatGPT rewrite Session Buddy from Chrome for Safari and get it working in roughly 20 minutes.

Done with ChatGPT· Intermediate· Oct 2026

What they did
They already had Session Buddy available in Chrome, so they gave ChatGPT permission to use that codebase as the starting point. From there, they asked it to make the extension work in Safari and take care of the install. The account doesn’t mention any extra hands-on steps.
How it went
Within around 20 minutes, Session Buddy was open and usable in Safari. They said the token cost would have been only a few dollars and that the work consumed about 6% of their $20/month plan.
Tips
A port like this is easiest when the original extension source can be inspected directly. If the agent might alter data, have it pause first and wait for approval before it continues.

Try it yourself with ChatGPT

I want to adapt [extension name] from Chrome to [Safari/another browser]. Use this source code or repository as the starting point: [paste link or files]. Update the extension so it runs in the target browser, point out any browser APIs or features that need substitutes, and give me build-and-install instructions I can follow locally. Stop and ask me before you do anything that would delete, submit, send, or otherwise change my data. End when I can load the extension and its core features work in [target browser].

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
