Overview

CustomGPT.ai launched in 2021, built around retrieval-augmented generation before that architecture had a common name in the mainstream chatbot market. The company positions itself against hallucination-prone general chatbots by scoping every answer to the content a customer actually ingests.

Customers point CustomGPT.ai at a website, help-center content, PDFs, or other documents; the platform indexes that material and builds a chatbot that answers using retrieval against the indexed content rather than the underlying model's general training data, streaming responses through a citation-backed API. Recent updates added AI Vision and image citations, letting the chatbot reference visual content alongside text sources.

Built for support and enablement teams that need a chatbot answering from company-specific facts rather than generic knowledge, deployable on a website, help desk, or internal tool via API. Pricing starts at $99/month for the Standard plan, moving to $499/month for Premium and custom Enterprise pricing above that, with a 7-day free trial rather than a permanent free plan.
