AI Newsletter Builder: Crawl Sites with Dumpling AI & Summarize with GPT-4o

This workflow is designed for newsletter writers, marketers, content creators, virtual assistants, and founders who need to curate and summarize web articles efficiently. It transforms a list of URLs into a polished, branded newsletter using AI-powered crawling and summarization.

Starting with a manual trigger (or schedulable), it reads article URLs from a Google Sheet. Dumpling AI crawls each site to extract full content, which is then split into individual items. A Code node cleans and structures the data into JSON format with fields like title, author, and content. An Edit Fields node merges all articles into a single JSON block for processing.

GPT-4o then generates concise summaries, key insights, and formatted HTML content tailored for newsletters. Finally, the workflow sends the ready-to-go email via Gmail, complete with branding and structure. This eliminates manual reading, summarizing, and formatting, delivering newsletters in minutes.

Benefits include massive time savings, consistent quality via AI, scalability for daily/weekly sends, and easy customization. Ideal for health & fitness newsletters curating latest research, tips, or industry news from multiple sources. Setup requires Google Sheets ID, Dumpling AI agent/API key, OpenAI credentials, and Gmail setup.
