Raspberry Pi 5 AI Document Understanding Kit — Extract and Query Invoices with Edge AI

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit lets you build a self-contained AI document processor that scans paper invoices and forms using Pi Camera, extracts text with PaddleOCR, and queries the extracted data using a local large language model running entirely on the Raspberry Pi 5. You’ll have a practical tool for automating data entry from physical documents, completely offline.

What You'll Build

You’ll build a compact, desk-mounted scanning station with integrated lighting that captures high-resolution images of invoices and forms. The Pi 5 processes the image, runs PaddleOCR to extract text and tables, then feeds it to a local LLM for querying — like asking “What is the total amount due?” and getting an instant answer. The system stores everything on NVMe SSD for fast inference and a growing document archive.

What You'll Learn

• Setting up PaddleOCR on Raspberry Pi 5 for text extraction from document images
• Configuring a local large language model (LLM) offline on a Pi 5 with NVMe storage
• Integrating Pi Camera Module 3 for consistent document imaging with optimal lighting
• Querying structured data using natural language via LLM integration
