Detects and recognizes text across 100+ languages using a two-stage deep learning pipeline: a text detection model (EAST-based) identifies text regions and bounding boxes in images, then a text recognition model (CRNN-based) decodes characters within those regions. Outputs structured JSON with character-level confidence scores and spatial coordinates. Supports both CPU and GPU inference with automatic model selection based on language and hardware availability.
Unique: Combines lightweight EAST detection with CRNN recognition in a unified pipeline optimized for 100+ languages; uses PaddlePaddle's dynamic graph execution for efficient inference on heterogeneous hardware (CPU, NVIDIA GPU, Kunlun XPU, Ascend NPU) without code changes. Knowledge distillation reduces model size by 40-50% vs baseline while maintaining accuracy.

Parses document layouts (tables, text blocks, figures, headers) using a hierarchical detection and recognition pipeline that identifies semantic regions beyond raw text. Combines object detection (YOLOv3-based) to locate structural elements with specialized recognition models for tables (cell extraction, row/column parsing) and text blocks (reading order inference). Outputs structured Markdown or JSON preserving document hierarchy and spatial relationships.
Unique: Hierarchical detection-recognition architecture that identifies structural elements (tables, text blocks, figures) separately from raw text, enabling semantic-aware document decomposition. Uses PaddlePaddle's graph optimization to parallelize detection and recognition stages, reducing latency vs sequential pipelines.

Supports multiple inference backends (PaddlePaddle native, ONNX, TensorRT) for deployment flexibility.
Unique: Fuses visual and textual embeddings in a unified transformer architecture rather than cascading OCR-then-LLM; supports multiple inference backends (PaddlePaddle, ONNX, TensorRT) enabling deployment across heterogeneous hardware.

Combines OCR output with large language models to perform semantic document understanding tasks: key-value extraction, entity recognition, document classification, and question-answering. Routes OCR results through a configurable LLM backend (supports OpenAI, Anthropic, local models via Ollama) with prompt engineering optimized for document understanding. Implements chain-of-thought reasoning for complex extraction tasks and handles multi-page document aggregation.

Translates document content across languages while preserving layout and structure using a specialized translation pipeline that combines OCR, layout-aware translation, and document reconstruction. Uses machine translation models (supports multiple backends) with document-level context awareness to maintain consistency across pages. Outputs translated documents in original format (PDF, Markdown) with spatial layout preserved.
Unique: Combines OCR, layout analysis, and translation in a unified pipeline that preserves document structure across languages. Uses document-level context in translation models to maintain consistency across pages. Supports multiple translation backends and outputs both human-readable (PDF, Markdown) and machine-parseable (JSON) formats.
vs alternatives: Preserves document layout better than naive OCR-then-translate-then-reconstruct; faster than manual translation; cheaper than professional translation services for high-volume processing; maintains document structure better than generic translation APIs
