Xberg

Extract clean text, tables, and structured data from documents and code — no format detection, no OCR setup, no stitched-together libraries. One engine, 15 language bindings, runs anywhere.

Xberg is the next iteration of Kreuzberg. Same document-intelligence engine, rebuilt and rebranded under a fresh v1 line.

Feed documents → get clean text, tables, metadata, transcripts, code intelligence · Run it library, CLI, REST API, or MCP server · No GPU needed · Stream multi-GB files · Cache results.

Documents · Images · Spreadsheets · Email · Archives · Code · Audio · Video

Quick start · What you get · Capabilities · CLI · Docs

Feed any document—get structured text. Extract, batch, stream, or crawl.

What you get

Point Xberg at anything — a PDF, a spreadsheet, a scanned image, an audio file, 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.

What it does	How
Extract from 97 formats	PDFs, Office, images, HTML, email, archives, scientific publications, and code — intelligent MIME detection, streaming for large files.
6 output formats	Plain text, Markdown, Djot, HTML, JSON tree structure, or Structured (JSON with OCR metadata and bounding boxes).
Code intelligence	Functions, classes, imports, symbols, docstrings from 306 programming languages. Syntax-aware chunking for RAG pipelines.
Crawl & recurse	Follow URLs, extract documents from within documents (nested archives, embedded PDFs). Auto/Document/Crawl modes.
OCR on demand	Tesseract, PaddleOCR, Candle, or VLM backends — fallback chains, extensible via plugins. Confidence scores. Language auto-detection.
Transcription	Whisper ONNX for audio/video tracks (MP3, M4A, WAV, WebM, MP4).
Embeddings & search	Local (ONNX models) or provider-hosted (OpenAI, Anthropic, Google, 143 providers via liter-llm). Reranking.
Structured outputs	LLM-powered extraction — local (Ollama, LM Studio, vLLM) or remote (OpenAI, Anthropic, Google).
Enrichment	NER, redaction, summarization, translation, QR code detection, page classification, keyword extraction (YAKE/RAKE), language detection, layout detection, table extraction, token reduction (TOON).
Batch & parallel	Process 100s of documents in parallel. Per-file timeouts. Configurable batch concurrency (`max_concurrent_extractions`).
Caching	Content-hash cache keys — skip re-extraction when the file and config are unchanged.
Deployment	Library, CLI (12 commands), REST API (`xberg serve`), MCP server (9 tools, 3 prompts, 4 resources), Docker.
