How I Built an AI Newsletter Agent with CREAO (Step-by-Step)

Resources: CREAO: https://agent.creao.ai/@derekcheungsa Kit API Documentation: https://developers.kit.com/api-reference/broadcasts/create-a-broadcast Sign-up to free newsletter: https://aifornoncoders.com/newsletter Learn how to build an AI newsletter agent with CREAO that researches trends, pulls YouTube videos, and sends newsletters via Kit — all from one conversation. In this CREAO tutorial, I'll show you how to go from a simple chat prompt to a permanent, scheduled Agent that teaches itself new APIs from documentation. CREAO is an AI Super Agent that lets you build automated workflows using natural language — no code, no terminal, no API key configuration. In this video, we build a personalized newsletter generator step by step: first as a simple Gmail workflow, then we lock it into a permanent Agent with one click, schedule it to run every morning, add a YouTube channel as a source, and finally teach CREAO the Kit (ConvertKit) API from a documentation URL. The result is a fully automated newsletter system that compounds over time — every API you teach CREAO becomes a permanent Skill available to all future Agents. What makes CREAO different from ChatGPT, Claude, Manus, or n8n is that what you build outlives the conversation. The workflow doesn't die when you close the chat — it becomes a permanent, scheduled tool that runs without being reinvented each time. This tutorial demonstrates the full Solve - Solidify - Scale workflow, plus the Auto-API Integration feature where CREAO learns any API from its documentation and saves it as a reusable Skill.
