Generate Summaries from Uploaded Files using OpenAI Assistants API

This n8n workflow automates the generation of structured summaries from uploaded files using OpenAI's Assistants API with File Search and Code Interpreter enabled. Users submit files through a form, which are then uploaded to OpenAI, attached to a thread, and processed by a custom assistant to produce JSON-formatted outputs including a concise title (5-10 words), a brief summary (1-2 sentences), key bullet points (3-5), and relevant tags (3-6 keywords).

The workflow handles polling for run completion, ensuring reliable results without manual intervention. It supports various file formats, making it versatile for processing reports, articles, presentations, and data files. Prerequisites include setting up an OpenAI assistant (ID starting with 'asst_') and API credentials in n8n via HTTP Header Auth.

Benefits include significant time savings for content curation, research, and knowledge management tasks. Use cases span content marketing (summarizing blog posts or whitepapers), legal review (key points from contracts), academic research (quick lit reviews), and business intelligence (extracting insights from reports). Its no-code setup in n8n allows rapid deployment for teams needing scalable document summarization.
