docling-project/docling

GitHub

An open-source document processing tool that parses diverse file formats, including advanced PDF understanding, and converts them into unified structured formats like Markdown or JSON for integration with generative AI applications.

CLOUDM0N decision
Trust FAIL · 0/100
Good fit if

Developers and teams building GenAI applications, agents, or RAG systems who need to ingest diverse document types like PDFs, Office documents, emails, and media files.

Watch out for

Python 3.9 is completely unsupported starting from version 2.70.0, requiring a migration to Python 3.10 or higher.

Practical intelligence

What matters before you adopt it

Problem it solves

The challenge of parsing and extracting semantic structures, layouts, tables, formulas, and multi-modal media from inconsistent, complex, and scanned document formats to make them ready for generative AI systems.

Best for
Developers and teams building GenAI applications, agents, or RAG systems who need to ingest diverse document types like PDFs, Office documents, emails, and media files.
Organizations requiring local, secure document parsing in air-gapped environments without sending sensitive data to external APIs.
Main trade-offs
Python 3.9 is completely unsupported starting from version 2.70.0, requiring a migration to Python 3.10 or higher.
Individual model usage may carry separate model licensing constraints distinct from the core MIT codebase license.
Why it stands out
Advanced PDF layout analysis, preserving reading order, table structures, code, and formulas.
Comprehensive OCR support for scanned documents and images across diverse formatting.
Plug-and-play integrations with prominent orchestration frameworks like LangChain, LlamaIndex, Crew AI, and Haystack.

Security notes
Supports local execution capabilities designed specifically for handling sensitive data and air-gapped environments safely.
Still unknown
The README does not specify details on performance benchmarks, processing latencies, or CPU/GPU hardware resource guidelines.
Does not outline manual steps or endpoints for configuring and querying the API server (docling-serve).
Does not specify which individual model packages are bundled or what their specific licenses are.
Adoption guidance
Adopt if
+ You need an open-source, locally runnable tool to parse multi-modal document formats (including PDFs, charts, video, and audio) into structured AI-ready data.
+ You are building agentic workflows with LangChain, LlamaIndex, Crew AI, or Haystack and need plug-and-play document parsers.
Avoid if
Your runtime environment is strictly locked to Python 3.9 or lower.
How it works & getting started
How it works
1.The user installs the docling library on a supported system running Python 3.10 or higher.
2.The parsing engine ingests a target document (such as a PDF, DOCX, email, audio, or video file).
3.Docling analyzes the layout, structure, tables, formulas, or transcriptions using built-in OCR, VLMs, or ASR models.
4.The data is structured into a unified DoclingDocument representation format.
5.The document is exported into the desired layout format such as Markdown, HTML, or lossless JSON.
Getting started
Install Docling using Python 3.10 or higher on macOS, Linux, or Windows (x86_64 or arm64).
Convert a document via the CLI to generate a structured .md file in the current directory.
Agent handoff
Use with any agent
