What is CustomGPT.ai?
CustomGPT.ai is a platform for building AI agents, described on the site as custom GPTs, from a company's own content. Instead of relying on a general-purpose chatbot, users upload or connect their business data and the resulting assistant answers questions based on that material.
The workflow is no-code: users connect data through over 1,400 supported document types and integrations such as Google Drive, HubSpot and Notion, and the content is synced in near real time. The assistant can then be deployed with out-of-the-box widgets embedded in a website, or accessed via a RAG API. The company highlights its anti-hallucination approach, aiming for answers grounded in the business data. Typical uses listed include customer support, internal knowledge search, onboarding and training, and website chatbots.
