Overview

CustomGPT is a no-code platform that lets organizations create AI agents grounded in their own data, including websites, documents, helpdesks, and video transcripts. The agents respond using only the ingested content, which helps reduce hallucinations and keep answers aligned with a company's verified information. Users can deploy agents as chat widgets, embed them in apps via API, or share them as standalone assistants for customer support, internal knowledge, research, and content workflows.

Skeptical, then convinced

I went in skeptical — most tools in this space overpromise. It actually delivers on team roles and access management, and supports many content sources and file formats caught me off guard. still, I'd recommend giving it a real trial.

Use it every day

Honestly didn't expect to like it this much. Team roles and access management is exactly what I needed, and supports many content sources and file formats. I do wish customization of underlying model behavior is limited, but I reach for it almost every day now and it just clicks.

Solid for our team

We rolled this out across the team last quarter and no coding required to build or deploy agents. Embeddable chat widget and developer API fits neatly into how we already work, and team roles and access management removed a step we used to do by hand. but it has held up under daily use.

Q&A

How can I deploy CustomGPT agents to my customers or team?

You can deploy agents as an embeddable chat widget on your site, integrate them into apps via the developer API, or share them as standalone assistants. This flexibility supports use cases like customer support, internal knowledge bases, research, and content workflows.

What content sources can I use to train a CustomGPT agent?

CustomGPT can ingest content from websites (via sitemaps), uploaded documents and files, helpdesk tools, and video transcripts. Agents then respond using only this ingested content to keep answers grounded in your verified business information.

Does CustomGPT prevent hallucinations, and how reliable are its answers?

Agents are designed to respond only from your ingested data, with citations to source material to help verify answers and reduce hallucinations. However, answer quality ultimately depends on the completeness and accuracy of the content you upload.
