Generate deep research markdown reports with GPT, Tavily Search, and Google Sheets

This workflow generates deep researched report in markdown format and saves it in Google Sheet, that I then use for generating blogs for my website - [Architjn Blogs](https://architjn.com/blog)

How it works 1. User submits a search topic through a form. 2. AI generates five deep-dive subtopics for that main topic. 3. AI creates a research report intro, title, and table of contents based on those topics. 4. Each subtopic is sent to a search API (Tavily) to collect top 5 sources. 5. AI writes detailed Markdown content for each subtopic using retrieved sources. 6. Final content, ToC, intro, and clickable sources are saved to a Google Sheet.

Set up steps - Requires connections to OpenRouter (AI), Tavily (search API), and Google Sheets. - Import into n8n and connect credentials for the above services. - Configure Google Sheet with proper column headers and grant edit access. - Estimated setup time: 20–30 minutes with working API keys. - Includes embedded instructions and markdown-style annotations for guidance.
