Go library, CLI, and HTTP service that converts PDF, DOC, DOCX, XML, HTML, RTF, ODT, Pages, and image files to plain text plus metadata (as JSON), aiming to be a single conversion entry point across many document formats rather than a PDF-specific tool. Optional OCR support (via Tesseract, enabled with the `ocr` build tag) handles image-based input. Its multi-format scope suits ingestion pipelines that need to normalize mixed document types into plain text.
