Frequently Asked Questions
What makes Lexa different?
Lexa is Cerevox’s enterprise-grade document parsing API that delivers 10x better performance and accuracy compared to traditional solutions. Unlike other APIs that struggle with complex layouts and structured data, Lexa uses state-of-the-art AI models to extract content with 99.9% accuracy while maintaining native async support and vector database optimization.
Key differentiators:
How quickly can I integrate?
You can start parsing documents in under 5 minutes:
Our Python SDK handles authentication, retries, and error handling automatically. We also provide comprehensive examples for Django, Flask, FastAPI, and async applications.
What formats does Lexa support?
Lexa supports 12+ file formats with consistent, high-accuracy parsing:
Documents: PDF, DOCX, PPTX, TXT, HTML, RTF
Spreadsheets: XLSX, CSV, TSV
Google Workspace: Google Docs, Sheets, Slides
Data: JSON, Parquet
All formats support advanced table extraction, image detection, and metadata preservation. File size limits range from 100MB for complex documents to 1GB+ for simple text files.
How does async processing work?
Lexa provides native async support with the AsyncLexa
client:
This enables concurrent processing of multiple documents, significantly improving throughput for batch operations.
How do I optimize for RAG applications?
Lexa is designed specifically for RAG workflows with built-in vector database optimization:
We provide pre-built integration examples for Pinecone, Weaviate, ChromaDB, and Qdrant.
What cloud storage integrations are available?
Lexa integrates with 7+ major cloud storage platforms:
What are Lexa's performance benchmarks?
