🚀 Built a SaaS Product Using n8n
Most people use n8n to automate workflows. I used it as the backend of a live SaaS product. 💡 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: ✅ Risk level (High / Medium / Low) ✅ What it actually means (no legal jargon) ✅ 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.
