This advanced n8n workflow streamlines the process of creating comprehensive Business Requirements Documents (BRDs) from form submissions. It begins when a user submits a form with project details and supporting files, which are then uploaded to Google Drive and recorded in Google Sheets for tracking. The workflow extracts text from uploaded PDFs, storing the content in a vector-based knowledge base for semantic retrieval. Two AI agents collaborate: one generates the overall BRD structure, and the other details specific business and functional requirements, leveraging retrieval-augmented generation (RAG) techniques. The generated content is merged into a Google Doc, converted to PDF, archived, and then sent to the requester via email. Finally, the system updates the tracking sheets, ensuring transparency and seamless document management. This workflow is ideal for organizations aiming to automate and optimize the creation and distribution of detailed project documentation.
