CustomGPT.ai

About CustomGPT.ai

CustomGPT.ai provides an API and Python SDK for building retrieval-augmented generation (RAG) AI agents, referred to as "projects" at the API level for backward compatibility. The API covers agent creation and management, document/page uploads and labeling, conversations and messaging (including an OpenAI-compatible format), team and role management, webpage context awareness, custom actions (MCP), multi-agent assignment, licensing, and billing and account limits. It also offers reporting and analytics endpoints covering customer intelligence, traffic, queries, conversations, and lead exports, as well as message-level trust scoring and accuracy verification.

The product is aimed at developers integrating custom AI chat agents into applications and platforms. Supported integrations and examples include Slack, Discord, Telegram, WhatsApp, Facebook, Instagram, Rocket Chat, MS Teams, Google Chat, a Chrome extension, n8n, make.com, and embeddable chat widgets (Next.js and Python+Vue versions), with additional open-source implementations (including voice and avatar widgets) available through the company's GitHub organization.

Authentication uses a bearer API key obtained from the user's profile in the CustomGPT.ai application. Additional resources referenced include an OpenAPI spec, a hosted Postman collection, a documentation-focused MCP server, and a status page for the API, agent, app, and website.
