Automating a short-form content pipeline with n8n (Reddit to Instagram Reels)

I kept seeing creators manually repeat the same workflow every day:
idea sourcing to script writing to video creation to publishing.

From an automation perspective, it felt like a perfect candidate for a fully automated pipeline, so I built one in n8n.

System overview (end-to-end):

• Reddit scraper pulls posts and top comments based on rules (subreddit, score, recency)
• LLM converts the thread into short Q&A-style scripts
• The video generation step adds voiceover and visuals.
• Formatting & metadata optimization for Instagram Reels
• Auto-publishing via API

The entire workflow runs without manual intervention once configured.

Why n8n worked well for this:

• Visual workflow made branching & error handling straightforward
• Easy integration with multiple APIs and AI models
• The self-hosted option keeps costs predictable
• Flexible enough to evolve as requirements change

Result: zero copy-paste, zero editing overhead, and consistent daily posting driven by live Reddit data.

Sharing this here because it’s a clean example of replacing a repetitive human workflow with a deterministic and AI-assisted system.
