What does LDX hub do?
LDX hub is a collection of AI-powered document processing APIs designed to handle messy, unstructured documents and convert them into something useful. Whether you need to extract text from a PDF in reading order, convert a scanned invoice into a Word file, or transform freeform text into clean JSON, LDX hub offers dedicated services for each task. It's not a general-purpose AI chat tool — it's a focused set of endpoints for developers who need to automate document workflows at scale.
The platform includes five main APIs. StructFlow extracts structured JSON from unstructured text, which is handy for pulling data out of reports or emails. RefineLoop improves the quality of XLIFF translation files — think of it as a smart proofreader for machine-translated content. RenderOCR uses OCR to convert PDFs and images into editable Office formats like Word and Excel, keeping the original layout intact. CastDoc does the same for PDF-to-Office conversion but without OCR, which means it works best on digital PDFs. ExtractDoc is a fast text extractor that outputs text in reading order, designed as a preprocessing step for downstream AI pipelines. All jobs run asynchronously — you upload a file, submit a job, and poll for results.
This tool is built for developers and teams who deal with high volumes of documents. Common use cases include automating invoice processing, digitizing scanned archives, preparing clean text for LLM ingestion, and refining translated content. The pay-per-credit pricing (1 credit = $0.0001) keeps costs predictable, and the MCP server allows integration with AI assistants like Claude Desktop. If you're building a document-heavy automation pipeline, LDX hub provides the building blocks.
