AI-Powered Webpage Summarizer Workflow with Cache Support

Transform Any Webpage Into Actionable Summaries with Smart Caching

Automatically extract and summarize content from any webpage using AI-powered summarization with intelligent 24-hour caching. This n8n workflow fetches webpage content, processes it through OpenAI's language models, and delivers concise summaries while optimizing performance through smart caching mechanisms.

What This Workflow Does

This automation workflow accepts a webpage URL and optional CSS selector as inputs from another n8n workflow. It first checks cached summaries to avoid duplicate processing within a 24-hour period. If no cache exists, the workflow fetches the webpage content, extracts the specified section using CSS selectors (or defaults to the entire body), and processes the content through an OpenAI Chat Model summarization chain. The generated summary is then cached for 24 hours and returned to the calling workflow.
