You will get an AI Document OCR & Data Extraction System for Your Business
Top Rated
Project details
Still processing invoices, forms, or scanned PDFs manually? Let AI do it in seconds.
I'll build you a production-ready AI Document OCR & Data Extraction System — the same solution I've already deployed for a real healthcare client handling prior authorization fax workflows at scale.
This isn't basic OCR. It's a full intelligent document processing pipeline that reads, understands, validates, and structures your data automatically — even from messy, handwritten, or low-quality scans.
🔍 What the System Does
Your team uploads documents (PDFs, images, scanned forms) → the system automatically:
✅ Extracts text using PaddleOCR
✅ Identifies key fields using Regex + LLM + Vision AI (VLM)
✅ Scores each field with a confidence level
✅ Validates and formats extracted data
✅ Stores results in PostgreSQL
✅ Flags low-confidence fields for human review
✅ Lets your team accept, edit, or reject values
✅ Learns from corrections to improve over time
✅ Exports to CSV or pushes via REST API
Document Types Supported
Invoices · Prior Authorizations · Insurance Forms · Medical Records · Contracts · Business Applications · Scanned Forms · Handwritten Notes · Approval Documents · Custom Layouts
