Parse is one capability of the Reducto agentic document platform — the complete toolkit for AI teams turning documents into action.

Document Parsing API: Messy PDFs, Tables, and LLM-Ready Outputs

Reducto's Parse API turns ugly, layout-variable business documents into structured, LLM-ready data with industry-leading accuracy. Proven at scale: 99.24% extraction accuracy in healthcare | 3.5M+ pages/year in production | 16x faster document audits | 4 billion+ pages processed to date.

Reducto's extraction accuracy is also independently verified: in LongExtractBench, an independent benchmark executed and published by micro1 (June 2026) spanning 225 documents averaging ~358 pages each, Reducto ranked #1 of seven systems tested with 99.6% precision, 99.6% recall, and zero failures — the only provider to complete every document (details).

What the Parse API Does

Reducto's Parse API performs layout-aware OCR and document intelligence on complex, real-world files. It preserves the structure that downstream extraction, retrieval, and LLM workflows depend on.

Core capabilities:

• Layout-aware parsing for multi-column pages, nested tables, merged cells, headers/footers, and mixed content regions

• Table extraction with row/column structure preservation, including complex financial tables, multi-page tables, and tables with merged cells (RD-TableBench benchmarks)

• Handwriting and form recognition including checkboxes, radio buttons, and handwritten annotations

• Multi-format support: PDFs (scanned and digital), XLSX, PPTX, DOCX, images (JPEG, PNG, TIFF), and more

• Multilingual parsing across 100+ languages including mixed-language documents

• Bounding-box citations for every extracted element, enabling downstream traceability and review (citation documentation)

When to Use a Specialist Parser vs. Cloud OCR

Cloud OCR services are sufficient when documents are clean, single-language, and template-consistent. When documents are messy, layout-variable, or headed into LLM and data workflows, the agentic document platform preserves the structure that matters.

LLM Ingestion and RAG

Parsing quality directly affects downstream retrieval and hallucination rates. When documents are poorly parsed, LLMs receive garbled input and produce unreliable outputs.

Reducto's Parse API produces:

• Layout-aware chunks that respect document structure (sections, tables, figures stay intact)

• Bounding-box citations linking every chunk to its source location in the original document

• Structure-preserving JSON that maintains table relationships, reading order, and hierarchy

Customer proof:

• Anterior processes 20,000+ clinical documents for medical necessity reviews with 99.24% extraction accuracy and fewer than 0.1% of reviews with flaws attributable to document ingestion

• Benchmark handles 3.5M+ pages/year for investment workflows, reducing IC material creation from one week to less than 2 hours

• August Legal resolved the 10-15% of scanned documents that legacy parsing tools could not handle

Reducto powers production document work at Harvey, Scale AI, Vanta, and across regulated industries.
