StrataSleuth

Inspiration

StrataSleuth was born out of a high-stress weekend during my own journey as a first-home buyer. I found a property I loved, but the seller demanded a signed contract by Monday morning. My conveyancer was offline for the weekend, and I was left staring at a 1000-page strata report and the contract alone. I realized then that first-home buyers are at a massive disadvantage: we lack the experience to spot "ticking time bombs" in dense legal documents, and the market moves faster than professional help can keep up. I built this to ensure no one else has to make a million-dollar decision completely in the dark, especially in hypercompetitive housing markets.

What it does

StrataSleuth is an AI-powered "Digital Conveyancer" designed for the high-speed property market. Users upload strata reports and sales contracts, and the app uses Gemini 3 Pro to instantly:

Flag Risks: Identify hidden "special levies," litigious committee history, or restrictive by-laws (like "no pets") in seconds.

Audit Finances: Extract data from scanned tables to check if the sinking fund is actually healthy.

Forecast: Generate a 10-year financial outlook, helping buyers see the long-term cost of ownership versus investment potential.

How we built it

We leveraged the Gemini 3 Pro API to handle the heavy lifting:

• Multimodal Document Parsing: We used Gemini 3’s native ability to "see" and interpret scanned, messy PDFs without needing a separate OCR layer.

• Deep Think Mode: To simulate the expertise of a conveyancer, we used Deep Think to cross-reference historical maintenance notes with current bank balances to predict future levies.

• Agentic Debugging: I used Gemini 3 as a pair programmer to build the complex financial forecasting logic, ensuring the math behind the 10-year projections was rigorous and accurate.

Challenges we ran into

The biggest challenge was the "Weekend Gap"—creating a tool that is fast enough for a 48-hour deadline but accurate enough to trust. We initially struggled with "hallucinations" in financial data, but by using Gemini 3 Pro's Thought Signatures and high-resolution media processing, we achieved the precision required for legal document analysis.

Accomplishments that we're proud of

We successfully built a tool that can "read between the lines." While most tools just summarize text, StrataSleuth can detect the vibe of a strata committee from meeting minutes, warning a buyer if the building has a history of poor management or hidden structural issues.

What we learned

Building this taught me that AI isn't just about automation; it's about democratizing expertise. Gemini 3 Pro has the reasoning capacity of a senior professional, and applying that to the real estate market levels the playing field for first-home buyers against seasoned developers and investors.

What's next for StrataSleuth

We want to integrate a "Saturday Inspection" feature where a user can take a photo/video of a physical contract at an open home and get an instant "Red Flag" summary on their phone before they even leave the building.
