High-performance document intelligence library
README 文档
README
Extract text, metadata, transcripts, and code intelligence from 96 file formats and 306 programming languages at native speeds without needing a GPU.
What and Why?
Kreuzberg is a document-intelligence framework with a Rust core and native bindings for 16 languages. It turns documents, images, audio, and source code into clean, structured text — extracting tables, metadata, transcripts, and code intelligence from 96 file formats and 306 programming languages.
Modern AI and RAG pipelines need fast, reliable extraction without a GPU or a stack of heavyweight dependencies. Kreuzberg delivers that from a single Rust core: SIMD-accelerated parsing, pure-Rust PDF, streaming for multi-GB files, and consistent output across every binding. Run it as a library, CLI, REST API, or MCP server.
OCR (Tesseract, PaddleOCR, EasyOCR, and VLM across 143 vision providers), Whisper audio/video transcription, chunking, language detection, embeddings, and structured LLM extraction are all built in.
Features
| Feature | Description |
|---|---|
| 96 file formats | PDF, Office, images, HTML/XML, email, archives, and academic formats across 8 categories |
| 306 languages | Code intelligence — functions, classes, imports, symbols, docstrings — via tree-sitter |
| Polyglot | Native bindings for Rust, Python, Node.js, WebAssembly, Ruby, Go, Java, Kotlin, C#, PHP, Elixir, R, Dart, Swift, Zig, and C |
| OCR | Tesseract (incl. WASM), PaddleOCR, EasyOCR, and VLM OCR across 143 vision providers — extensible via plugins |
| Transcription | Whisper ONNX transcripts for MP3, M4A, WAV, WebM, and MP4 audio tracks |
| LLM intelligence | Structured JSON extraction, embeddings, and VLM OCR through liter-llm, including local engines |
| Deployment | Use as a library, CLI tool, REST API server, or MCP server |
| High performance | Rust core with pure-Rust PDF, SIMD optimizations, full parallelism, and streaming for multi-GB files |
| Token-efficient output | TOON wire format uses ~30–50% fewer tokens than JSON for LLM/RAG pipelines |
| Extensible | Plugin system for custom OCR backends, validators, post-processors, extractors, and renderers |
Supported Formats
96 file formats across 8 categories — Office documents, images (OCR-enabled), web and structured data, email, archives, academic, and audio/video — plus code intelligence for 306 programming languages. See the format reference for the complete list.
