🚀 Built a SaaS Product Using n8n
Most people use n8n to automate workflows.
I used it as the backend of a live SaaS product.
đź’ˇ What I built
Legal Contract Risk Analyser
Upload a legal document → AI analyzes every clause → you get a full risk report in under 5 minutes.
This is not a workflow sitting inside the n8n canvas.
👉 It’s a real web app anyone can open and use.
⚠️ Why I built this
Most of us sign contracts we don’t fully understand.
- 20 pages of legal text
- 2–3 hours of reading
- Still unsure what’s risky
And the worst part?
The riskiest clauses don’t look risky.
Example:
“The Client accepts full responsibility for all third-party claims”
Looks harmless. It’s not.
And keyword search? Completely useless here.
🧠How it works
This is where things get interesting.
Instead of keeping everything inside n8n,
I split it into:
Frontend + Backend + AI pipeline
🔧 Under the hood:
→ n8n → runs the entire backend pipeline
→ Google Gemini → analyzes each clause, scores risk, rewrites it simply
→ Hybrid RAG (pgvector + BM25) → finds risky patterns using semantic + keyword search
→ Supabase → stores knowledge base + analysis results
→ HTML / CSS / JS → frontend UI
→ Netlify → makes it publicly accessible
🎯 What you get
Every clause gets:
âś… Risk level (High / Medium / Low)
âś… What it actually means (no legal jargon)
âś… A safer alternative
No more guessing. No more signing blind.
🧩 Who this is for
- Freelancers reviewing contracts
- Startups signing vendor agreements
- Business owners who can’t afford hidden risks
🔥 The real lesson
n8n is not just an automation tool.
It can be your backend for real AI products.
Same tool. Different thinking.
