How to embed ChatGPT on your website
You can't embed ChatGPT itself — OpenAI doesn't ship an embeddable widget for chat.openai.com. What you actually want, and what teams build, is a custom-trained ChatGPT-style chatbot embedded on your site. The chat experience looks and feels like ChatGPT, but it answers from YOUR content (your website, PDFs, and Q&A), uses the underlying GPT models behind the scenes, and runs on the chatbot platform's infrastructure — not your OpenAI account.
Chatmount is the platform for this. You sign up, train on your data, customize the widget, paste a one-line script into your site, and the ChatGPT-style chat appears in the bottom-right corner — ready to answer visitor questions, capture leads, and hand off to a human when needed.
You never expose API keys, manage rate limits, or get billed by OpenAI directly. Chatmount handles all of that.
Vanilla ChatGPT vs. embedded custom GPT
| Capability | Vanilla ChatGPT | Chatmount embed |
|---|---|---|
| Answers from your content | No — open internet only | Yes — your website + PDFs + Q&A |
| Source citations | No (in chat.openai.com) | Yes — URL or PDF page per answer |
| Lives on your website | No — only at chat.openai.com | Yes — one-line embed |
| Branded to your site | No | Yes — colors, icon, persona |
| Captures leads | No | Yes — in-conversation capture |
| Hands off to a human | No | Yes — operator dashboard |
| Manages model + billing | Your OpenAI account | Chatmount handles it |
| Setup time | N/A — not embeddable | 5 minutes |
What you get with the Chatmount embed
Everything you'd build yourself with the OpenAI API — and then some.
No OpenAI API key handling
Chatmount manages model selection, prompting, billing, and rate limits. You don't expose API keys, you don't get a surprise OpenAI bill.
One line of HTML
A single script tag drops the ChatGPT-style widget onto any site. Works with WordPress, Shopify, Wix, Webflow, Squarespace, and plain HTML.
Branded to match your site
Set primary color, position, bubble icon, welcome message, and suggested queries. Your widget, not a third-party logo.
Source-cited answers
Every answer can include the URL or PDF page it came from. No hallucinations — visitors see where the info originated.
Lead capture and human handover built in
It's not just a Q&A widget — capture qualified leads in the conversation and hand off to a human operator when intent is high.

FAQ
Frequently asked questions.
Everything teams ask before embedding a ChatGPT-style chatbot.
How do I embed ChatGPT on my website?
You can't embed ChatGPT itself directly — OpenAI doesn't ship a website widget. What you can do (and what teams actually want) is embed a ChatGPT-style chat widget that answers from YOUR content using OpenAI's underlying models. Chatmount is one of these widgets: train on your website/PDFs, paste a one-line script, and the widget appears on your site, ready to answer questions like ChatGPT but scoped to your content.
What's the difference between vanilla ChatGPT and an embedded custom-trained chatbot?
Vanilla ChatGPT (chat.openai.com) answers from the open internet and OpenAI's general training data. It doesn't know your products, your prices, or your policies. An embedded custom-trained chatbot — like Chatmount — answers from YOUR website, PDFs, and Q&A. It cites the source page so visitors can verify. It also captures leads, hands off to humans, and can be branded to match your site.
Do I need an OpenAI API key?
No. Chatmount handles all the model billing, rate limits, and prompt engineering on its own infrastructure. You don't expose any API keys, you don't manage usage, and you don't get a surprise OpenAI bill. Chatmount's pricing is based on your monthly message volume.
Which AI models are used?
Chatmount uses the latest generation of frontier models (GPT-class) for chat, plus OpenAI's text-embedding-3 for retrieval. We pick the best available model per task and update them as new versions ship — you don't manage model selection.
Can I create a custom GPT for my website?
Yes — that's effectively what Chatmount does. You upload your data sources (website, PDFs, Q&A), configure the bot's persona and behavior, and embed it on your site. It's a custom GPT in the practical sense: a ChatGPT-like interface trained on your specific content, with controls for what it answers and what it refuses.
Is this faster than building it myself with the OpenAI API?
Much faster. Building a website-embedded RAG chatbot from scratch involves: a vector database, an embedding pipeline, a chat UI, a deployment pipeline, rate limiting, billing tracking, system-prompt engineering, and ongoing model updates. That's typically a 2-4 week engineering project. Chatmount is 5 minutes.
Will the widget hurt my Core Web Vitals?
No. Chatmount uses a two-stage loader: a 3KB shell renders the floating bubble immediately; the full chat UI bundle only loads when a visitor clicks. Your LCP, INP, and CLS stay green. Many other 'embed ChatGPT' widgets eagerly load 100KB+ on every page and tank your PageSpeed score.
