CustomGPT.ai is a no-code AI chatbot builder that answers from a business's own documents and websites with cited sources, sold on flat monthly account plans.
CustomGPT.ai lets an organisation put an assistant in front of its own knowledge, so questions get answered from approved material instead of general model memory. Each reply links back to the document or page it came from. CustomGPT Inc., an independent company based in Needham, Massachusetts, builds and sells it. Work starts with an agent, a project that holds its own sources and settings. Sources include websites, help desks, knowledge bases, PDFs, Office files, YouTube videos and audio, with connectors for Google Drive, Notion, Confluence, SharePoint and the Zendesk Knowledge Base, and Auto-sync keeps website content current. Persona settings define how the agent speaks and behaves. Agent stats track queries and user feedback, while Customer Intelligence classifies the intent and emotion behind each question. Conversation history exports to JSON, XLSX or CSV, and the RAG API exposes the same agents to developers. The product is aimed at support leads, knowledge managers and membership associations that field repeated questions about policies, benefits and renewals. Small teams can build and embed an agent without code, while engineering teams use the API on the same account. Buyers choose a flat account plan that sets agents, queries and seats, add packs when usage grows, and can start on a trial; larger organisations negotiate an Enterprise contract with model choice and priority queries. The simplest deployment is a chat widget dropped onto a help centre or product site with a script tag, an iframe, the WordPress plugin or a Shopify or Wix embed. Support teams then link the agent to Zendesk, Intercom or Freshdesk, and sales teams to HubSpot or Pipedrive, so conversations reach the records they already keep. Internally, the same agent can sit in Slack and answer staff from handbooks stored in SharePoint or Confluence. Zapier links conversations and captured details to the other systems a team relies on. It fits organisations whose answers already live in documents and must stay traceable to them.
