This workflow runs once a week and sends an AI-curated digest to my inbox.
It’s designed to be lightweight and completely automatic.
Here’s how it works:
- Weekly Trigger: Set to run every Monday at 7:15 AM.
- Date & Time node: it extracts the current week number to add it to the email subject line.
- HTTP Request to Perplexity AI: it runs a research query using the
sonar-deep-researchmodel to retrieve the top 10 updates on AI tools for the current week. - AI Agent: the response from Perplexity is passed to a GPT-4.1-mini model, which rewrites it as a markdown-formatted email using clear formatting, emojis for relevance
, and links extracted from the response. - Gmail Node: the email is sent automatically to my chosen recipients, with a subject like:
Updates AI 🐓 - Week 20/52
→ n8n version: 1.90.2

Any other tips?
- I used a custom prompt to structure the AI output into a clean, numbered markdown format, with icons for relevance.
- You could easily adapt this for any topic, not just AI. Just tweak the search prompt!
