As a developer, I am always looking for ways to solve real-world friction. In April 2026, I launched SnapQuote AI on the Google Play Store. It is a mobile app designed specifically for field contractors who hate spending hours doing manual calculations and typing up invoices after a long day of physical work.
Why Contractor Estimating Needs AI
Traditional estimates require the contractor to measure rooms, list materials, write prices down on paper, and later type them into a spreadsheet. With SnapQuote AI, a contractor can simply press record, say: "We need to paint 3 bedrooms, replace the baseboards in the hallway, and clean up the debris. Total labor will be $1500 and materials should be about $350."
The AI automatically transcribes the recording, extracts the line items, and generates a structured quote within seconds.
"AI isn't about replacing the contractor; it's about saving them from the hours of screen time they spend on paperwork every night."
The Architecture Stack
To make this application production-ready, we chose a robust hybrid architecture:
Frontend: Built with Flutter and managed using Riverpod for robust state management.
Backend: Node.js and Express serving an API schema wrapper.
AI Pipeline: Groq Whisper for sub-second audio transcription, feeding into LLM structures to output structured JSON.
Database: Supabase for user authentication and PostgreSQL data storage.
Setting up this structure allowed us to launch a fast, lightweight mobile app that feels responsive even on slow cellular connections in the field. Try it out on the Google Play Store today!
