Custom ChatGPT

Custom ChatGPT for Your Website

Turn your website content into an AI assistant visitors can ask directly — without sending them to ChatGPT.

What people mean by “Custom ChatGPT”

When someone searches for a custom ChatGPT for their website, they are rarely looking for a general chatbot. They usually want an assistant that knows their business.

An AI trained on their own content
An AI that answers business-specific questions
An AI assistant available to customers
Something that behaves like ChatGPT, but uses their website as the knowledge source

A Custom GPT inside ChatGPT can be useful for that last idea — especially for internal work or a shared GPT experience. If the goal is for website visitors to ask questions without leaving the page, the usual fit is an embeddable website AI chatbot, not a GPT that only lives in ChatGPT.

Custom GPT vs website chatbot

Both can feel conversational. They serve different places and different users.

Custom GPT

Usually accessed through ChatGPT
Useful for internal workflows, personal assistants, or shared GPT experiences
Visitors may need to leave the business website to use it

Website AI chatbot

Lives directly on the business website
Uses website content as knowledge
Answers visitor questions in context
Can support customer support and lead generation on the same page

Can a Custom GPT be embedded on a website?

People also search for ways to embed a custom GPT, add ChatGPT to a website, or put a ChatGPT chatbot on their site. The underlying request is usually simpler than the wording.

I want visitors to ask questions about my website without leaving my website.

If that is the job, an embeddable website AI chatbot is the direct answer. WebsiteChat is built for that: it reads selected pages, answers from that content, and sits on your site as a widget. It is not an official ChatGPT product, and it is not a Custom GPT hosted inside ChatGPT. It is a website chatbot that gives visitors a ChatGPT-like way to ask.

How WebsiteChat works

A short path from the site you already have to a widget visitors can ask.

Website

Your existing public website. Answers start from pages you already published.

Crawl

WebsiteChat reads selected pages so the assistant knows what you offer.

Knowledge

That content is organized into searchable knowledge for retrieval.

AI

Relevant passages are retrieved to answer the visitor’s question.

Widget

Visitors ask directly on your website — no detour to ChatGPT.

What WebsiteChat can answer

The useful questions are the ones already answered somewhere on your site. Typical examples:

“Where is your office?”
“Which product is suitable for a small business?”
“Do you provide installation?”
“How much does this service cost?”
“Can you support customers in Japanese?”
“How can I request a quote?”

Replies come from the website content you connect. If a page does not cover the topic, WebsiteChat should not invent an answer from outside your site.

Where a website ChatGPT-like assistant helps

Customer support

Answer common questions using existing website content, including after hours.

Product questions

Help visitors understand products, services, plans, specifications, and differences.

Lead generation

Guide high-intent visitors toward contact, a quotation, a demo, or an inquiry.

Multilingual visitors

Let people ask in their preferred language even when the site structure is complex.
