Codex is an absolute beast for getting real work done, but most people barely scratch the surface of what it can actually do. In this video I take you from zero to a fully working YouTube comment intelligence system, complete with skills, automations, a deployed dashboard, and browser use QA. By the end you'll know exactly how to set up Codex, build reusable workflows, and ship real projects without babysitting every step.

They spent $340K going digital. Then every document took longer. A manufacturing company scanned 847,000 pages into SharePoint and kept the old filing logic. THE PROBLEM: - Old paper workflow: 20 minutes per document lifecycle - New scanned workflow: 26 minutes - PDFs were uploaded into folders manually - No full-text OCR search - Misfiled PDFs were harder to find than paper THE n8n WORKFLOW: - Scanner upload trigger receives PDFs - OCR parser converts scans to searchable text - Classifier tags supplier, contract, invoice, report, or compliance doc - Metadata extractor stores key fields - Search index replaces folder navigation - Validation node catches upside-down or unreadable scans - Routing node sends docs to the correct team THE RESULTS: - Scanned “digital” system: 433 hours/month - True automated system: 12.5 hours/month - Audit retrieval went from days to minutes - Staff stopped opening PDFs manually just to identify them THE LESSON: Paperless is not the same as automated. The goal is not to scan documents. The goal is to stop manually filing and finding them. Where has a client replaced paper with PDFs but kept the exact same process?
