Converts PDF, PowerPoint, Word, Excel, EPUB, and image files into a unified internal document representation through a pluggable provider architecture. Each provider handles format-specific extraction (e.g., PDF uses pdfplumber or PyPDF2, Office formats use python-pptx/python-docx), normalizing diverse input types into a common block-based schema for downstream processing. The provider pattern enables extensibility without modifying core pipeline logic.
Unique: Uses a provider abstraction layer that decouples format-specific extraction logic from layout analysis and rendering, allowing new document types to be added via entry points without modifying core converter code. This contrasts with monolithic converters that hardcode format handling.
vs alternatives: More extensible than single-format converters like pdfplumber-only solutions; cleaner separation of concerns than tools that mix extraction and rendering logic.
Uses pre-trained deep learning models (via detectron2 or similar vision transformers) to identify document structure elements (text regions, tables, figures, headers, footers) and their spatial relationships through polygon-based bounding box detection. The layout builder constructs a hierarchical block tree that preserves 2D positioning information, enabling accurate reconstruction of document structure even in complex multi-column or non-linear layouts. This approach outperforms rule-based heuristics for varied document designs.
Unique: Implements layout detection via pre-trained vision models rather than heuristic-based rule engines, capturing complex spatial relationships through learned features. Stores layout as polygon coordinates in a hierarchical block tree, enabling both accurate reconstruction and efficient querying of document structure.
vs alternatives: More robust than regex/heuristic-based layout detection (e.g., PyPDF2) for complex documents; faster than rule-based systems for varied layouts but requires GPU for production throughput.
Processes multiple documents in parallel using a configurable batch pipeline that distributes work across available GPUs or CPU cores. Implements job queuing, progress tracking, and error handling for large-scale document conversion. Supports distributed processing via Python multiprocessing or async I/O, with configurable batch sizes and worker counts. Enables efficient processing of document collections for RAG systems or data extraction pipelines.
Unique: Implements batch processing with configurable multi-GPU distribution and progress tracking, using Python multiprocessing or async I/O for parallelization. Supports custom batch sizes and worker counts, enabling tuning for different hardware configurations and document types.
vs alternatives: More efficient than sequential single-document processing; supports multi-GPU distribution unlike CPU-only tools; includes progress tracking and error handling unlike basic batch scripts.
Provides a centralized configuration system that manages model selection, processing options, LLM provider credentials, and output format settings. Supports environment variable overrides for deployment flexibility, YAML/JSON configuration files for complex setups, and dynamic component discovery via entry points. Enables users to customize behavior (e.g., which layout model to use, OCR provider, LLM service) without code changes.
Unique: Implements a hierarchical configuration system with environment variable overrides and dynamic component discovery via entry points, enabling flexible customization without code changes. Supports multiple configuration sources (env vars, files, CLI args) with clear precedence rules.
vs alternatives: More flexible than hardcoded configuration; supports environment-based overrides unlike static config files; component discovery enables extensibility without modifying core code.
Provides a REST API server (FastAPI-based) that exposes document conversion as HTTP endpoints, enabling integration with external systems and web applications. Supports file upload, conversion with configurable options, and streaming output. Implements request queuing, timeout handling, and resource limits to prevent abuse. Enables Marker to be deployed as a microservice for document processing pipelines.
Unique: Implements a FastAPI-based REST server that exposes document conversion as HTTP endpoints with request queuing and resource limits. Enables Marker to be deployed as a microservice, supporting concurrent requests and integration with external systems.
vs alternatives: More accessible than Python library for non-Python applications; enables microservice deployment unlike library-only tools; supports concurrent requests with proper resource management.
Detects form fields (text inputs, checkboxes, radio buttons, dropdowns) using layout analysis and specialized form processors. Extracts field values and metadata (field name, type, position, default value) and outputs structured data (JSON, CSV) suitable for downstream processing. Supports both filled and unfilled forms, with optional LLM-based field value correction for low-confidence extractions.
Unique: Integrates form field detection into layout analysis pipeline, identifying field types and positions through spatial analysis. Extracts both field metadata and values, with optional LLM-based correction for low-confidence extractions. Outputs structured data (JSON, CSV) suitable for downstream processing.
vs alternatives: More comprehensive than simple text extraction from forms; supports field type detection unlike basic OCR; includes LLM-based correction for accuracy improvement.
Performs optical character recognition (OCR) on document regions where native text extraction fails, using Tesseract or cloud-based OCR APIs as fallback. Integrates text line detection models to identify individual text lines and their bounding boxes, enabling character-level positioning for accurate reconstruction. The system automatically routes content through OCR when PDF text extraction yields low confidence or when processing scanned/image-based documents, with configurable confidence thresholds.
Unique: Implements adaptive OCR routing with confidence-based fallback — automatically escalates to OCR when native text extraction confidence is low, and integrates both local (Tesseract) and cloud-based OCR APIs with pluggable provider pattern. Text line detection models provide character-level positioning for precise layout reconstruction.
vs alternatives: More flexible than single-OCR-engine solutions; better than PDF-only text extraction for scanned documents; supports multiple OCR backends unlike tools locked to one provider.
Detects table regions via layout analysis, extracts cell content through OCR or native text extraction, and reconstructs table structure (rows, columns, merged cells) using heuristic-based cell alignment and optional LLM-based refinement. The table processor handles complex tables with merged cells, nested headers, and irregular layouts by analyzing cell boundaries and content relationships. LLM processors can be invoked to correct misaligned cells or infer missing content, trading latency for accuracy.
Unique: Combines heuristic cell alignment with optional LLM-based refinement — uses spatial analysis to reconstruct table structure, then optionally invokes LLMs to correct misaligned cells or infer missing content. Supports pluggable LLM services (OpenAI, Anthropic, local models) for accuracy tuning without rewriting extraction logic.
vs alternatives: More accurate than regex-based table extraction; supports LLM refinement unlike pure heuristic tools; better handling of merged cells than simple grid-based approaches.
