What is this tool?
CustomGPT.ai is a platform for building chatbots trained on your own content that answer with citations and are designed to decline when they don't have an answer. It is aimed at businesses wanting accurate, source-grounded answers for customers and staff. Citations and a built-in 'I don't know' behaviour are its emphasis. Answer quality depends on the content you provide, and any security or privacy posture should be verified before relying on it.

Read full overviewHide full overview
You connect content — a sitemap, files, and other sources — and it builds a chatbot that answers from that material, attaches citations to responses, and is configured to say it doesn't know rather than guess, deployable as a website embed, in LiveChat, or via API with public or private access.
It suits support, knowledge, and operations teams that want grounded answers with a visible source trail, and developers who want to embed or extend it.
Answers reflect the content you give it, so coverage and freshness matter; the stated privacy-first and accuracy behaviours are buyer-relevant claims worth confirming against the current terms.
Is this right for you?
Quick fit check against how you actually work.
Choose this if

Consider alternatives if
- Your content base is thin or stale
- You want open-domain chat
- You need deep custom agent logic
Key features
What you can actually do with this tool.
Content-trained chatbot
Builds a bot on your sitemap, files, and sources, so answers come from your material.
Citations on answers
Attaches sources to responses, so an answer can be traced rather than trusted blindly.
Declines unknowns
Is configured to say it doesn't know rather than make up an answer when content is missing.
Access control
Offers public or private access, so a bot can serve customers or stay internal.
Embed and API
Embeds on a site or in LiveChat and exposes an API for custom use.
Multi-source data
Pulls from multiple sources, so a bot reflects a fuller knowledge base.

Frequently asked
Common questions about this tool, answered.
How does it avoid making things up?
Grounding in your content plus citations is the mechanism, and it defers instead of guessing when coverage is missing — so it only holds if your content actually answers the question.
Is it secure enough for our data?
It states a privacy-first approach, but that's buyer-critical, so confirm the current data, access, and retention terms before relying on it.
Where does it run?
Deployment spans a site widget, LiveChat, or programmatic use, with public or private access set by audience.
What if a question isn't in our content?
It defers or points to a human rather than fabricating an answer, so thin or missing documentation is the main limit to plan around.
How it compares
Context for choosing between this tool and alternatives.
For a content-grounded chatbot, the emphasis differs; CustomGPT.ai stresses citations and declining unknowns, while DocsBot leans to actions across tools, SiteSpeakAI to a one-line website widget, and Chatbase or Botpress to configurable building. Compare on whether traceable, cautious answers or broader actions matter most.
