Agent One for ChatGPT
Publish an AI agent to the web from a ChatGPT conversation.
Tell ChatGPT what your agent should know. Agent One turns it into a live agent with its own page, a link you can share, and a chat widget you can embed on any website. It answers the public's questions and can collect leads.
In ChatGPT, open Plugins and search for Agent One. Also available in Codex.

What to ask
Paste the information, then ask ChatGPT to publish it.
ChatGPT drafts the agent's name, greeting, instructions, knowledge, and starter questions from what you give it. Agent One publishes the agent and returns the link.
“Turn this menu and our opening hours into an assistant customers can ask questions on our website.”
You get: A public agent page that answers questions about the menu and hours, plus an embed snippet for your site.
“Make a public page where people can ask about our spring pottery workshop. Collect a name and email from anyone who wants a spot.”
You get: A shareable agent page with a name and email form, so interested visitors become leads.
“Publish an AI agent that answers questions about this rental listing.”
You get: A link you can post with the listing that answers questions about the property you pasted.
“Create a chatbot from our return policy and FAQ, and give me the code to add it to our site.”
You get: A chat widget for your existing website, answering from the policy and FAQ you provided.
What gets created
A live agent the public can talk to.
A public agent page
The agent gets its own page at a link like https://your-name.agnt.one/assistant. Anyone with the link can ask it questions.
An embed snippet
A short piece of HTML to paste into an existing website, so the same agent appears there as a chat widget.
Optional lead capture
Ask for it and the agent shows a short name and email form, so you can follow up with interested visitors.
New Agent One accounts can publish one agent, and it stays live for 7 days. To keep it online after that, choose a plan.
After it's live
Watch what visitors ask and improve the agent from the same chat.
Nothing about your agent changes until you confirm the exact text. Some features, such as conversation insights, depend on your Agent One plan.
See what visitors ask
“What have visitors been asking my agent this month?”
Improve weak answers
“Find answers visitors disliked and draft better knowledge for them.”
Follow up on leads
“Draft follow-up emails for this week's leads.”
Check who's waiting
“Who is waiting for a person? Draft a reply to each.”

Questions
How do I put my information on a website as an AI assistant from ChatGPT?
Connect the Agent One plugin in ChatGPT, paste the information the assistant should know, and ask ChatGPT to publish it. Agent One creates a live agent with its own page link and an embed snippet for an existing website.
Do I need a website already?
No. Every agent gets its own hosted page on agnt.one that you can share as a link. If you do have a website, paste the embed snippet to add the agent there as a chat widget.
Can the agent collect leads?
Yes. Ask for lead capture and the agent shows a name and email form. You can review the leads and draft follow-ups in ChatGPT or in the Agent One dashboard.
How long does a published agent stay live?
New Agent One accounts can publish one agent, and it stays live for 7 days. To keep it online after that, choose an Agent One plan.
Can I change the agent after it's published?
Yes. Ask ChatGPT to add knowledge or rewrite the agent's instructions. Nothing changes until you confirm the exact text. More settings, such as custom domains, are in the Agent One dashboard.
What isn't it for?
Agent One publishes AI agents that talk to the public. It doesn't build full websites with custom layouts, host files, or send email or text campaigns, and it isn't meant for private, internal-only chatbots.
