Overview

Quotee is an AI-powered contractor estimating system available as a Progressive Web App and on the App Store. It uses GPT vision capabilities to parse uploaded images and screenshots, extracting structured data to generate accurate quote calculations for service businesses.

Problem Context

Contractors and service professionals spend significant time manually creating estimates from photos, measurements, and reference materials. The process is error-prone, inconsistent, and does not scale. Existing estimating tools require manual data entry and offer no intelligence in the parsing stage.

System Design Decisions

  • GPT vision as the primary parsing engine — contractors simply photograph or screenshot reference materials.
  • PWA architecture for mobile-first field use without app store friction, with an additional native App Store listing.
  • Structured output formatting maps vision-parsed data to predefined service categories.
  • Automatic tax and subtotal calculation eliminates manual arithmetic errors.

Architecture

Pipeline architecture: image upload triggers vision parsing via the OpenAI API, parsed data flows through a normalization layer mapping extracted items to the service catalog, and a calculation engine produces the final estimate with taxes and totals. The PWA shell provides offline capability for field environments with intermittent connectivity.

Stack Breakdown

Next.js provides the application framework with both server and client rendering. TypeScript enforces type safety across the parsing and calculation pipeline. OpenAI API powers the vision parsing engine. Tailwind CSS creates a clean, mobile-optimized interface. Postgres stores estimate history and service catalogs. Deployed on Vercel with serverless functions handling the vision API integration.
