Automating My Pinterest Content Pipeline with n8n + AI (Free Setup)
I was spending way too much time digging for content on Pinterest, so I decided to automate the process.
With a bit of tinkering in n8n, I ended up building a workflow that turns viral TikToks into Pinterest-ready pins — completely free to run.
⚡ What the workflow does
I just send a keyword like healthy recipes, 10, and the workflow:
- Searches TikTok using Apify
- Filters results for high engagement (1M+ views, 1K+ shares, 20–60 sec)
- Downloads the top 3 videos (without watermarks — tricky part 😅)
- Uploads them to Google Drive
- Generates Pinterest titles & descriptions with a free LLM (DeepSeek via OpenRouter)
-
Logs everything in a Google Sheet with status =
Pendingfor review
💡 Why it matters
- Saves hours of manual searching
- Runs on free tiers:
- n8n (self-hosted)
- Apify free credits
- OpenRouter free tier
- Google Drive + Sheets
And because I still review before posting, Pinterest doesn’t flag low-quality content.
🛠️ Challenges I ran into
- Getting AI to output clean JSON (regex gymnastics to strip markdown)
- TikTok CDN requires Referer headers or it throws 403 errors
- Deduplication to avoid grabbing the same video twice
✅ Final thoughts
This workflow is lightweight, flexible, and basically zero-cost.
It also reminded me how powerful tools like n8n can be for automating entire content pipelines with just APIs + logic.
