Xberg
The fast, precise document-intelligence engine — for every language.
Point Xberg at anything — a PDF, a scanned image, a spreadsheet, an audio file, a URL, a whole archive, or a source tree — and get back clean text, tables, metadata, and structured data. One engine handles format detection, reading, OCR, and extraction, so you never stitch a pipeline together from a dozen libraries.
107 formats · 141 file extensions · 371 code languages · 15 language bindings · 6 output formats · OCR · transcription · embeddings
The fastest, most precise open-source document and PDF-to-Markdown engine — see the benchmarks.

Xberg is the next iteration of Kreuzberg. Same document-intelligence engine, rebuilt and rebranded under a fresh v1 line.
What you get
Point Xberg at anything — a PDF, a spreadsheet, a scanned image, an audio file, a URL, an archive, a source tree — and get back clean, structured content you can use right away. One core does the format detection, reading, and extraction, so you don't assemble a pipeline yourself. Call it from Rust, Python, Node.js, Go, Java, C#, Ruby, PHP, Elixir, Dart, Swift, Zig, WASM, Kotlin, or C FFI, and run it as a library, CLI tool, REST API, or MCP server.
| Capability | What you get |
|---|
| 107 document formats | PDFs, Office, images, HTML, email, e-books, scientific publications, and structured data across 141 file extensions, with intelligent MIME detection and bounded extraction controls. |
| URLs & the web | Point Xberg at an http(s) URL — it fetches and extracts a single document, or crawls and follows links (Auto / Document / Crawl modes via the crawlberg engine). Requires the url-ingestion feature. |
| Audio & video transcription | Speech-to-text from MP3, M4A, WAV, WebM, and MP4 tracks via Whisper ONNX (tiny → large-v3). Requires the transcription feature. |
| Archives, traversed | List and recursively extract nested .zip, .tar, .gz, .7z — documents inside documents — guarded by zip-bomb, compression-ratio, and nesting-depth limits. |
| OCR on demand | Tesseract, PaddleOCR, Candle, or VLM backends — fallback chains, confidence scores, language auto-detection, extensible via plugins. |
| Layout & tables | ML layout models (PP-DocLayout-V3, RT-DETR) and table structure (TATR, SLANet) reconstruct reading order and cell grids for clean Markdown. |
| Code intelligence | Functions, classes, imports, symbols, docstrings from 371 programming languages. Syntax-aware chunking for RAG pipelines. |
| Embeddings & search | Local (ONNX) or provider-hosted embeddings (165 providers via liter-llm), sparse and late-interaction, cross-encoder reranking. |
| Enrichment | NER, keyword extraction (YAKE/RAKE), summarization, translation, redaction, page classification, QR detection, language detection, token reduction (TOON). |
| Structured extraction | Schema-driven JSON straight from any document via local (Ollama, LM Studio, vLLM) or hosted LLMs — no prompt engineering. |
| 6 output formats | Plain text, Markdown, Djot, HTML, JSON tree, or Docling DocTags, plus registered custom renderers. |
| Runs anywhere |
Capabilities marked requires a feature are Cargo feature flags on the core crate (url-ingestion, transcription, reranker, layout/ORT). Prebuilt language packages and the Docker image bundle the common set; a from-source build enables only what you select.
