Pedrita IA

Inspiration

I own a small stone business in Brazil and saw the same problem every day: fabricators spend too much time answering repetitive questions, calculating countertops, preparing quotes, and explaining materials to customers.

Most AI tools are generic. I wanted to build an AI coworker that truly understands the stone fabrication industry.

That idea became Pedrita IA.

What it does

Pedrita IA is an AI assistant specialized in the stone industry.

Through WhatsApp, it can:

• Answer technical questions about natural and engineered stone.
• Calculate countertops from customer measurements.
• Generate technical drawings.
• Prepare quotations.
• Help customers choose materials.
• Support stone fabricators during their daily work.

The project also connects with Marmorista PRO, a web application for generating professional technical documents.

How I built it

The project was built using OpenAI models together with custom business logic.

Main technologies include:

• OpenAI GPT
• Codex
• Node.js
• WhatsApp Cloud API
• Redis
• Supabase
• Cloudflare Pages

The biggest challenge was teaching the AI to understand real fabrication workflows instead of acting like a generic chatbot.

Challenges

Stone fabrication involves many technical rules, measurements, edge profiles, materials, and construction details.

The AI had to become reliable enough to assist professionals while remaining easy for customers to use through WhatsApp.

Accomplishments

Pedrita IA is already being tested by real businesses and continues to improve based on real user feedback.

This project demonstrates how AI can transform highly specialized industries that are often overlooked by modern software.

What's next

Future plans include ERP integration, automatic order management, customer memory, advanced technical drawings, and expansion to other construction-related industries.
