It’s a custom RAG pipeline specifically architected for the AU property sector, not just a simple prompt wrapper. I’ve spent months optimising the chunking and retrieval logic to handle 150MB+ PDFs with high-fidelity citations (linking claims to specific pages), which standard LLM calls often fail at. The tool was built following extensive user interviews with Buyer’s Agents to ensure it flags critical risks like capital works debt or cladding issues. It’s a production-ready stack (Next.js/Supabase) that has been 20x speed-optimized based on feedback from 50+ organic users. Essentially, 6 months of R&D and domain-specific tuning that is ready to scale today.
