An AI support agent for your site, live in five minutes
helpGPT answers your visitors' questions from your own content, with citations and honest refusals.
One script tag
Paste it on any site. The widget streams answers and falls back gracefully in every browser.
Grounded in your content
FAQ pages, help centers, PDFs. Every answer cites the source it came from.
Honest refusals
When the answer is not in your content, the agent says so instead of guessing.
How it works
Add your content
Paste FAQs, crawl your help center, or upload PDFs. Everything is chunked, embedded, and indexed automatically.
Test in the playground
Ask real visitor questions and watch answers stream with citations back to your sources. Off-topic asks get refused.
Embed the widget
One script tag on your site. Cross-domain chat with streaming answers, sources, and a fallback for every browser.
Set up in minutes
helpGPT
A replayed conversation from the playground.
Instructions
Describe the agent's job in plain language. It represents your site, listens carefully, and resolves issues with care.
Guardrails
Refuse what is off-topic, never promise features you have not shipped, and hand off to a human when it is unsure.
Sources
Connect FAQs, help center pages, and PDFs. Answers only come from what you added, and they cite it.
What you get
Citations on every answer
Each reply links back to the exact source passage, so visitors can verify and read on.
A monthly cap you control
Set the message limit per plan. When it runs out, the widget says so instead of silently billing you.
Domain locking
Verify the domains your widget may run on, or leave it open while you test.
Conversation insight
See what visitors actually ask, which answers landed, and where your content has gaps.
“The bubble in the corner of this page is helpGPT itself, answering from this site's own content. Try it.”
