Comprehensive Research Report Generator with Gemini AI, Web Search & PDF Delivery

This workflow is an autonomous AI research assistant that transforms a single topic into a comprehensive, multi-chapter report. Designed for researchers, students, and content creators, it automates the entire process from planning and online research to writing, formatting, and delivering a final PDF report directly to your email.

How it works

Trigger: The workflow begins when a user submits a research topic and an email address through a form.

• AI Planning: An AI agent breaks the main topic into five focused subtopics. It then generates an engaging report title, a detailed introduction, and chapter headings, saving this initial structure to a Google Sheet.
• Parallel Research and Writing: The workflow then splits into five parallel paths, one for each subtopic. In each path, it uses the Tavily Search API to gather real-time information from the web. A dedicated AI writer then synthesizes this research into a complete, well-formatted HTML chapter with inline citations.
• Content Aggregation: As each chapter is completed, its content, sources, and section titles are saved to the central Google Sheet.
• Final Assembly and Delivery: Once all chapters are written, the workflow compiles the title, introduction, a newly generated table of contents, all chapters, and a complete list of sources into a single HTML document. This document is sent to APITemplate.io to be converted into a professionally formatted PDF, which is then emailed as an attachment to the address provided in the form.
