ChatGPT-User: what it is and how to allow or block it

If you block it, ChatGPT (live browsing) can't read your site when someone asks about what you do, and it won't quote you. To show up in answers, let it in.

Check whether ChatGPT-User can read your site

Tarsier tests your site with this and other AI crawlers and tells you who gets in, who doesn't and why.

What it is

ChatGPT (live browsing). Opens your page when someone asks ChatGPT for it or pastes the link.

Like most AI crawlers, it reads the HTML exactly as your server sends it: whatever your site paints with JavaScript may never reach it.

How it identifies itself

Mozilla/5.0 (compatible; ChatGPT-User/1.0; +https://openai.com/bot)

This is what it sends in the User-Agent header. In robots.txt you only use the short name: ChatGPT-User.
