11 Self-Hosted AI Workflow Templates for n8n + Ollama (No API Keys Needed)

Hey everyone!

I’ve been building n8n workflows that use Ollama instead of cloud AI APIs. The main idea: get all the AI automation benefits without paying for API keys or sending data to third parties.

What I Built

A pack of 11 production-ready workflows that connect n8n to your local Ollama instance:

Content & Marketing

  • AI Blog Writer Pipeline — Enter a topic, get a polished blog post through a 4-stage pipeline (research, outline, draft, edit)
    • Social Media Content Generator — One topic becomes optimized posts for Twitter, LinkedIn, Reddit, and Instagram
      • YouTube-to-Newsletter Pipeline — Paste a YouTube URL, get a formatted email newsletter
        • Multi-Platform Content Repurposer — Feed in one blog post, get back six platform-optimized versions
      • Sales & Business

        • Lead Scoring & Enrichment — Webhook-triggered, scores leads 1-100 with AI analysis
          • Competitor Intelligence Monitor — Weekly autopilot that scrapes and analyzes competitor changes
            • Email Auto-Responder — Classifies emails, filters junk, drafts context-aware replies
              • Support Ticket Router — Classifies tickets, detects sentiment, auto-replies to simple questions
            • Productivity

              • Document Summarizer — Webhook API that summarizes any document with auto-generated Q&A
                • Meeting Notes Summarizer — Paste transcripts, get structured summaries with action items
                  • Data Extractor — Pull structured data from unstructured text
                • Why Local AI?

              • The big advantages over cloud APIs: zero monthly cost, complete data privacy (nothing leaves your machine), no rate limits, works offline, and GDPR compliant by default.
            • Requirements

            • n8n (self-hosted)
              • Ollama with llama3:8b or similar model
                • 8GB+ RAM recommended
              • Where to Get It

            • I put together a downloadable pack with all 11 workflows plus documentation: Self-Hosted AI Workflow Pack
          • Each workflow comes with in-workflow sticky notes explaining how it works, so you can customize them for your use case.
        • Would love to hear what workflows you’d find most useful, or if there are other local AI use cases you’d want automated!
