Clausify Development Journey

Building an AI-powered contract analysis platform for freelancers. Follow along as I architect, develop, and deploy a full-stack SaaS application from scratch.

About This Project

Clausify is an AI-powered contract analysis platform that helps freelancers understand legal agreements without expensive attorney fees. Upload a contract, get instant AI analysis highlighting risky clauses, and receive negotiation strategies tailored to freelancer interests.

Why I'm Building This: To demonstrate my full-stack development capabilities, AI integration skills, and ability to architect production-ready applications with modern technologies.

  • Integrated shadcn/ui component library for accessible UI
  • Configured Supabase with PostgreSQL and pgvector extension
  • Created database schema with vector similarity search capabilities
  • Implemented Row-Level Security (RLS) policies for data isolation
  • Built environment automation scripts for multi-machine development
  • Deployed initial landing page to Vercel

Week 2: Core Features & AI Integration

Upcoming
Planned: 10/27/25

Build the contract upload component with drag-and-drop support, implement PDF text extraction, integrate Groq API for contract analysis, and create the results display interface.

Planned Features:

Week 3: Vector Search & Comparison

Upcoming
Planned: 11/3/25

Implement semantic similarity search using pgvector, build clause comparison features, seed the standard clause database, and create version diff tracking.

Planned Features:

  • Generate vector embeddings for contract clauses
  • Implement semantic similarity search with cosine distance
  • Build clause comparison interface
  • Seed database with 100+ standard contract clauses
  • Create version diff tracking for contract iterations
  • Optimize vector search performance with IVFFlat indexing
  • Add AI-generated summaries of changes between versions

Week 4: Polish & Documentation
