# CustomGPT.ai

> CustomGPT.ai is a no-code platform for building AI agents (chatbots)
> from your own business content using retrieval-augmented generation (RAG).

> company and platform founded in 2023.

CustomGPT.ai transforms business documents, websites, and knowledge bases
into source-citing AI assistants in minutes, without coding. Every response
includes citations linking back to source material. The platform is SOC 2
