The Problem

Sensitive Documents and Third-Party Risk

Businesses process thousands of sensitive documents daily. Sending invoices, contracts, and receipts to third-party cloud services creates privacy concerns and compliance risks. Existing solutions either require cloud APIs or lack the intelligence to handle varied document layouts without constant template maintenance.

Approach & Solution

Local-First AI Processing

DocExtract uses AI-powered field extraction with local LLMs, requiring no cloud APIs. OCR processing for PDFs and images is handled via Tesseract, and all processing happens entirely on your machine.

Key features include a clean dashboard with confidence scoring, batch processing for up to 20 documents at once, and export to CSV or JSON. The solution was built because we wanted to process sensitive business documents without sending them to third-party cloud services while still leveraging modern AI capabilities.

The Result

Privacy-First Document Intelligence

DocExtract keeps everything local while leveraging modern AI capabilities. It successfully handles varied layouts of invoices, contracts, and receipts with zero template configuration, empowering teams to process documents without compromising on privacy or accuracy.
