## Description

Sparrow is an LLM document extraction platform and vision-based inference engine designed to convert images and PDFs into validated structured data. It functions as an agentic workflow orchestrator that chains classification, extraction, and validation tasks into multi-step pipelines.

The system distinguishes itself through a backend-agnostic inference layer that manages models across local GPUs, Apple Silicon, and cloud providers. It employs coordinate-based visual grounding to map extracted text to precise bounding box coordinates and utilizes hint-based model steering to guide attention and normalize data formats.

The platform covers document intelligence workflows, including specialized image-based table processing to maintain structural integrity and schema-driven validation to verify the correctness of extracted fields. It also provides a document analysis dashboard for monitoring API performance, usage analytics, and system health.

The architecture includes a plugin-based extension system for integrating third-party libraries used in indexing and orchestration.
