Document Processing

UsageGuard provides advanced document processing capabilities that enable you to easily integrate AI-powered Retrieval Augmented Generation (RAG) into your applications.

Overview

Our document processing pipeline handles the complete lifecycle of documents:

Secure Upload: Documents are uploaded directly to secure cloud storage using presigned URLs
Text Extraction:
- Support for multiple document formats:
  - PDF (including scanned documents with OCR)
  - Microsoft Office (DOCX, XLSX, PPTX)
  - Plain text files (TXT, CSV)
  - Rich text formats (RTF)
- Automatic OCR for scanned documents
- Preservation of document structure and formatting
- Multi-language support
Content Processing:
- Text cleaning and normalization:
  - Removal of redundant whitespace and formatting
  - Character encoding normalization
  - Special character handling
  - Noise reduction
- Content chunking for optimal AI processing:
  - Intelligent splitting based on semantic boundaries
  - Configurable chunk sizes
  - Overlap between chunks to maintain context
  - Preservation of document structure
- Automatic language detection
- Optional content filtering and PII detection
AI Processing:
- Generation of document embeddings using state-of-the-art models
- Vector storage for semantic search capabilities
- Optional content classification and PII detection
- Support for multiple embedding models:
  - Multilingual-E5-Large (default)
  - Custom models (enterprise plans)

Security & Compliance

All document operations are:

End-to-end encrypted
Access controlled via your authentication tokens
Tracked for audit purposes
Compliant with data privacy requirements

Processing Status

Documents go through several processing states:

queued: Document is waiting to be processed
indexing: Document is being processed (text extraction, embedding generation)
completed: Processing finished successfully
failed: Processing failed (check error details via status endpoint)

Integration

To integrate document processing into your application, use our Document APIs. These APIs handle all the complexity of document processing while providing a simple interface for your application.
