What is Custom GPT?

Updated May 2026

A custom GPT is a personalized version of ChatGPT you can configure with your own instructions, files, and tool connections, then share with others.

Custom GPTs let you connect external tools via OpenAPI or MCP, so the GPT can call your real business data. For a withlove user, a custom GPT can be configured to call your agent's tools (book_slot, get_pricing, etc).

Frequently asked questions

How do I connect my withlove agent to a custom GPT?

Paste your /<slug>/openapi.json URL into the GPT's 'Actions' section. ChatGPT reads the OpenAPI doc and learns how to call your agent. Add an API key (issued in /me/integrations) for authentication.
