Transform Docs to Engaging LinkedIn Posts with GPT & Email Approval

This n8n workflow transforms uploaded documents (PDF, DOCX, TXT) or pasted text into engaging LinkedIn posts via AI-powered copywriting. It starts with a form trigger for file upload, detects file type using a Switch node, extracts content with specialized nodes (e.g., Google Docs for DOCX), and generates polished posts using an OpenAI GPT-4.1-mini agent optimized for LinkedIn best practices.

After generation, it sends an approval email via SMTP with the draft post and an option to add images. An IMAP Email Trigger monitors responses; upon approval, it automatically publishes to LinkedIn via OAuth integration. This ensures quality control while saving hours on content creation.

Benefits include time savings for professionals, consistent high-engagement posts, and flexibility across document formats. Ideal use cases: turning meeting notes, reports, or articles into shareable LinkedIn content for marketers, executives, and consultants. Setup requires connecting OpenAI, LinkedIn, Google Docs, and email services; customize prompts for brand voice.
