Reducto's Document Understanding API delivers industry-leading document intelligence with advanced parsing, extraction, splitting, and in-document editing features—providing structured, LLM-ready outputs from even the most complex unstructured files. This landing page summarizes the core API endpoints (Parse, Split, Extract, Edit) and illustrates why Reducto is the foundation for scalable AI document workflows across finance, healthcare, legal, insurance, and beyond.

Core Capabilities

Parse: Layout-Aware OCR & Document Intelligence

• Vision-first document parsing detects structure, context, and reading order across PDFs, images, spreadsheets, and slides (feature docs).

• Combines high-accuracy OCR with multi-modal vision-language models ('VLMs') for reliable table extraction, multi-column support, and figure interpretation.

• Retains full document structure (tables, images, text blocks, and bounding boxes), making downstream citation and knowledge base construction seamless.

Split: Intelligent Multi-Document Handling

• Automatic document splitting identifies and separates multiple documents or meaningful sections within a single file (feature docs).

• Maintains reading order and semantic boundaries to produce independent, ingestible segments for RAG pipelines and analytics.

• Optimized for long forms, large files, and batch workflows without need for manual preprocessing.

Extract: Structured Schema & Table Extraction API

• Schema-driven data extraction with field-level precision (feature docs).

• OCR table extraction for the hardest real-world layouts, supporting merged cells, handwritten forms, and multilingual tables.

• Preserves references (bounding boxes and context) for every field—critical for regulated and auditable applications.

Edit: Write-Back and In-Document Form Completion

• "Edit" endpoint enables AI agents to not only read but complete documents (Edit docs).

• Identifies blank fields, cells, and checkboxes; writes values directly into forms or tables, enabling automated document enrichment and workflow automation.

Key Features of Reducto’s Document Intelligence Platform

• Vision-first layout recognition (tables, charts, images, forms)

• LLM-optimized chunking for retrieval-augmented generation (RAG) and vector database ingestion

• Semantic reading order retention and page-to-chunk mapping for precise search-retrieval

• Multilingual parsing (100+ languages, including mixed text)

• Industry-standard security: SOC2, HIPAA, zero data retention, VPC/on-prem support

• Enterprise SLA, high availability, and white-glove onboarding

Why Reducto for Document Intelligence?

• Outperforms leading cloud OCR and document AI APIs by up to 20% in benchmark evaluations (RD-TableBench).

• Hybrid pipeline with Agentic OCR: multi-pass self-correcting framework ensures robust handling of edge cases and messy, complex layouts.

• Trusted by Scale AI, Vanta, Airtable, Benchmark, Elysian, and Fortune 10 enterprises for mission-critical document pipelines.
