# DOXTRAKT

> DOXTRAKT is a privacy-first, client-side document processing engine and developer-grade OCR suite. It extracts high-fidelity text, handwriting, structured tables, and visual artifacts (logos, signatures, stamps) from PDFs, PowerPoint slides, and high-resolution images with zero persistent cloud storage.

## Core Capabilities

- **Client-Side Sandbox Processing**: Documents and presentation slides are rendered directly in-memory within the browser using WebAssembly and Web Workers. Raw documents are never written to disk or persistently stored on servers.
- **Multimodal AI OCR & Transcription**: High-precision optical character recognition preserving line breaks, paragraph hierarchy, markdown tables, and cursive handwriting annotations.
- **Visual Artifact Detection**: Automatic detection, isolation, and bounding-box extraction of official stamps, corporate logos, signatures, and embedded graphics.
- **Intelligent Multi-Format Conversion**: Convert documents and slide graphics into clean Markdown, semantic HTML, or structured JSON datasets.
- **PDF Manipulation Suite**: Local client-side PDF editing, page merging, reordering, page extraction, watermarking, and redaction.

## Security & Defense-in-Depth Architecture

- **Magic Byte Validation**: Binary signature verification on all uploaded files to eliminate file extension spoofing.
- **Strict In-Memory Boundaries**: 50 MB upload caps and safe rendering limits to preserve browser execution stability and neutralize decompression bombs.
- **Filename Sanitization**: Neutralizes path traversal, null bytes, and malicious filesystem symbols.
- **Isolated AI Prompts**: Server-side OCR proxies enforce strict system instruction sandboxing against prompt injection attacks embedded inside scanned documents.
