## What This Package Provides

- **Document intelligence core** — extract text, tables, images, metadata, entities, keywords, and code intelligence from one API.
- **Format coverage** — PDF, Office, images, HTML/XML, email, archives, notebooks, citations, scientific formats, and plain text.
- **OCR choices** — Tesseract, PaddleOCR, EasyOCR where supported, VLM OCR through liter-llm, and plugin hooks for custom backends.
- **Same engine as every binding** — Rust, Python, Node.js, Go, Java, PHP, Ruby, .NET, Elixir, R, WASM, Kotlin Android, Swift, Dart, Zig, and C FFI share the same Rust implementation.
