Short answerA Custom GPT lives inside ChatGPT, so you can link to it but not embed it as your own chat widget. To put an assistant on your site, rebuild it somewhere that offers an embed or build your own chat on a model API.
What you can do with a GPT as it is
Share a link that opens it in ChatGPT. Visitors need access to ChatGPT, and OpenAI plans to retire Custom GPTs, so do not build a customer experience on that link; see the dates.
Options for a real on-site assistant
- A chatbot platform with a website widget. Check each platform's official embed documentation.
- A custom build. Your developer calls a model API from your own chat interface: API rebuild.
- A standalone hosted page. Link to a page that holds the chat. GPT Migrator provides a page at gptmigrator.com/your-bot. It is a page you link to, not an embeddable widget.
Questions to ask before choosing
- Does it need to look like part of your site?
- Do visitors need to log in?
- Does it call outside services (Actions)?
- Who maintains it?
Need your GPT running again without ChatGPT?
GPT Migrator can host your instructions and files as a standalone chat page for $47 per month. You bring your own OpenAI or Anthropic API key. It answers from your instructions and files and does not run GPT Actions.
