Can I embed a Custom GPT on my website?

No. OpenAI doesn't provide an embed code or widget API for GPTs, and OpenAI blocks other sites from loading chatgpt.com in an iframe, so a Custom GPT can only be opened as a link that takes visitors to ChatGPT's own site.

Why does ChatGPT block iframes?

OpenAI sets response headers on chatgpt.com that tell browsers to refuse rendering it inside a frame on another domain, a common defense against clickjacking. It also means there's no supported way to wrap a GPT's interface inside your own page.

Do visitors need a ChatGPT account to use a Custom GPT?

Yes. Opening any GPT from the Store requires being signed in to ChatGPT, on the free tier or a paid plan, which is friction an anonymous website visitor won't tolerate for a support question.

What's the difference between a Custom GPT and a RAG chatbot widget?

A Custom GPT runs inside ChatGPT's own interface with a fixed, manually uploaded knowledge file. A RAG chatbot widget like AmueAI embeds directly into your website via a script tag, requires no login, and indexes your live pages and documents so answers stay current as your content changes.

A Custom GPT built in ChatGPT's GPT Store cannot be embedded on your website. OpenAI has never shipped an embed code, an iframe snippet, or a widget API for GPTs, and nothing in the GPT Store lets a visitor skip the ChatGPT login screen either. If you want a chat window that lives on your own site and answers from your own content, you need a different tool: either the OpenAI API wired up by an engineer, or a dedicated chatbot widget platform that handles retrieval, hosting, and the embed script for you.
