Building an AI-Powered Content Summarizer Workflow in n8n

Now that you have set up your n8n environment, let's create a practical workflow to summarize content from web pages. We'll build an AI-powered content summarizer that:

2. Fetches the web page content.

4. Returns the summary as structured JSON.
