Sortex.AI

Intelligent document processing platform for transport and logistics. Upload PDF or image documents, automatically classify them, extract structured data with OCR + LLM, validate against business rules, and review results in a human-in-the-loop UI.

Features

• Document classification — automatically identifies 11 transport document types (CMR, Invoice, Bill of Lading, Air Waybill, Customs Declaration, and more) using weighted keyword scoring with fuzzy matching and LLM fallback
• OCR extraction — PaddleOCR (default) or Tesseract for text extraction from PDFs and images
• LLM field extraction — structured field extraction via Ollama (qwen2.5:3b) or OpenAI, with per-document-type schemas
• Validation engine — config-driven business rules with confidence scoring
• Review UI — human-in-the-loop correction interface with side-by-side document viewer
• Authentication — JWT access/refresh tokens with role-based access control (RBAC)
• File security — magic bytes validation, filename sanitization, rate limiting

Quick Start

Prerequisites

• Docker and Docker Compose
• Ollama installed locally (for LLM extraction)

1. Clone and configure

git clone https://github.com/HopeyCodeDS/sortex-ai.git
cd sortex-ai

Create a .env file in the project root:

POSTGRES_USER=sortex
POSTGRES_PASSWORD=sortex
POSTGRES_DB=sortex

MINIO_ACCESS_KEY=minioadmin
MINIO_SECRET_KEY=minioadmin

JWT_SECRET_KEY=change-this-in-production

DEFAULT_LLM_PROVIDER=ollama
OLLAMA_BASE_URL=http://host.docker.internal:11434
OLLAMA_MODEL=qwen2.5:3b

CORS_ORIGINS=http://localhost:3000

2. Pull the Ollama model

ollama pull qwen2.5:3b

3. Start services

docker-compose up -d

This starts PostgreSQL, MinIO, Redis, the FastAPI backend, and the React frontend.

4. Access the app

Service	URL
Frontend	http://localhost:3000
Backend API	http://localhost:8000
API docs (Swagger)	http://localhost:8000/docs
MinIO console	http://localhost:9001

Default login: admin@docflow.ai / admin123
