How to get ChatGPT to browse a website I've created

I’ve used ChatGPT to help design a website and used codex to create the website. Codex can browse to the website at localhost or using the in app browser but chatGPT cannot do that. I have also deployed the website to. public host (Vercel) but ChatGPT cannot browse to it. In fact Codex also cannot browse to that although it says the website is returning 200.

Does anyone know a workaround for this situation? A way for ChatGPT to browse to my public site? I’ve had to take multiple screen captures and paste to ChatGPT but that is far from ideal.

This is all on a Mac with the latest ChatGPT / Codex app.

It can only search public web, stuff that has been indexed like you find on google etc. If you can not find it on google chances are a AI search call won’t find it either.

With public indexing stuff like this is possible.

Another workaround is to build a Custom GPT with an Action connected directly to your site.

Instead of relying on ChatGPT Search; or waiting for Google to index your pages, you could expose the site’s content through a simple API.

For example:

GET /api/page?path=/about
GET /api/search?q=pricing

You would then add an OpenAPI schema for those endpoints in the GPT’s Actions configuration.

This is different from giving ChatGPT a URL and asking it to browse the page. The Action sends a direct API request to your server, so search indexing is not required.

The endpoint must be publicly accessible or use supported authentication, and it should return clean text or structured JSON rather than a fully rendered webpage.

For a site you control, this is likely the most reliable approach.

Because;

For a newly deployed or low-traffic personal site, an AI search request is unlikely to surface it immediately because the page may not yet have been discovered or indexed by the relevant search system.

Digging deeper so I’m adding;
I found to use Codex in the ChatGPT desktop app with its built-in browser, rather than regular ChatGPT Search.

Start the site locally, open the Codex browser, and navigate directly to the localhost address, for example:

http://localhost:3000

Then ask Codex to inspect the rendered page at desktop, tablet, and mobile sizes. It can check the layout, responsiveness, interactions, console errors, and failed network requests. Developer mode helps because it gives Codex access to more browser debugging information.

For the public version, open the exact Vercel deployment URL in the same browser. A 200 response only confirms the server returned something; it does not necessarily mean the app rendered correctly. Codex should check for JavaScript errors, missing assets, redirects, authentication, environment-variable problems, and failed API requests.

A prompt like this may work

Open this site in the browser and inspect the actual rendered interface. Test desktop, tablet, and mobile sizes. Check the layout, spacing, responsiveness, navigation, forms, interactions, accessibility, console errors, and failed network requests. Fix any issues you find, reload the page, and test it again.

A Custom GPT Action is still useful when you want ChatGPT to retrieve structured content through an API, but it is not the right solution for visually reviewing the website. Search, Actions, and browser testing are separate things..

That’s brilliant. Thank you for the suggestions and taking the time to produce such a detailed answer.

Happy to help! :rabbit_face:
Good luck!
