PageIndex Description
PageIndex is an advanced document AI platform designed for comprehending lengthy and intricate documents, offering accurate, verifiable responses that are directly linked to the original sources. Instead of relying on embeddings, chunking, or vector databases, it employs a reasoning-based retrieval method that converts each document into a tree-like index, reflecting the natural way individuals explore sections, subsections, pages, and content. A reasoning model then analyzes this structure to identify where to find pertinent information, thereby enabling context-aware retrieval that is both traceable and easy to explain. Users have the capability to upload a wide variety of documents such as reports, legal files, research papers, technical manuals, medical records, textbooks, and business plans, allowing them to pose questions that include line-level citations for thorough verification. PageIndex is adept at handling ultra-long documents that can span thousands of pages and is proficient in interpreting not only text but also tables, charts, figures, and images. This comprehensive understanding ensures users can efficiently extract relevant data from extensive materials.

For developers, ARGOS Identity offers two APIs.
ARGOS ID Check (KYC/eKYC): launch the hosted Liveform from one URL in a browser or an iOS, Android or React Native WebView, or build your own capture UI on the Verify engine APIs. Your backend uses the REST API to fetch submissions, review pending cases, delete or partially delete data for GDPR and CCPA requests and download AML reports, and receives webhooks for created, submit, approved, rejected, updated, delete and AML result events. Each check reads the ID with OCR plus MRZ and PDF417 barcode checks, tests ID and selfie liveness, matches the face to the ID photo and screens the user against sanctions and PEP lists, with ongoing monitoring afterwards. Data is processed and stored in the region chosen for each project (US or South Korea), sensitive fields are encrypted with AES-256 at rest, and payload encryption is optional. A migration API imports existing verification records.
ARGOS Omni (Review Ops Agent): authenticate with an x-api-key header, create a profile under a workflow, upload files, text or JSON as items (PDF, DOCX, XLSX, PPTX, images, CSV, HTML, EML and more) and start an asynchronous analysis. The result follows the output schema you defined, with a verdict of verified, rejected or pending_review and the reasoning and source step for each extracted value, and every completed analysis can be downloaded as a PDF report.

Unsiloed
Unsiloed AI is an enterprise document intelligence platform built to transform unstructured documents into structured, LLM-ready data. The platform processes PDFs, images, spreadsheets, scans, and multimodal files, then outputs clean JSON, Markdown, or structured fields for AI agents, LLM applications, vector databases, and data warehouses. Its core capabilities include parsing, extraction, and document splitting, allowing teams to use each function independently or chain them into a full production pipeline. Unsiloed’s parser converts complex documents into Markdown while preserving structure across text, tables, charts, figures, forms, handwriting, signatures, and visual hierarchy. Its extraction engine pulls schema-specific fields into JSON and uses domain awareness to understand documents such as invoices, contracts, financial reports, healthcare records, and regulatory filings. Its splitting tools can separate mixed files into individual documents or break long documents into retrievable chunks while preserving parent-child relationships and surrounding context. The platform is powered by proprietary dual-stream vision models that combine a data stream for tokens and entities with a layout stream for bounding boxes, alignment, indentation, and visual structure. Unsiloed is designed to solve the problem of fragile OCR and DIY pipelines that break when document layouts change. For enterprise AI teams, Unsiloed provides a more reliable document layer for turning high-value unstructured data into assets that can be searched, reasoned over, and used in production AI systems.

LandingAI
LandingAI Agentic Document Extraction (ADE) is a document intelligence platform that transforms documents into structured, auditable data through AI-powered extraction and processing capabilities. The platform is designed to process complex business documents, including contracts, financial statements, regulatory filings, forms, invoices, reports, and multi-page records with high accuracy. ADE combines vision-based AI, agentic orchestration, and data-centric learning to extract information while preserving document structure, layout, tables, headings, and contextual relationships. Every extracted data point includes confidence scores, source references, page numbers, and coordinate-based traceability to support validation and governance requirements. The platform provides APIs for parsing, splitting, and extracting information from documents, making it suitable for integration into enterprise workflows and applications. ADE supports retrieval-augmented generation (RAG), search, analytics, compliance automation, reporting, reconciliation, and document-driven business processes. LandingAI offers deployment flexibility through cloud, on-premises, and private environment options while supporting enterprise security requirements such as SOC 2 Type II, GDPR, HIPAA compliance, and zero-data-retention configurations. The platform is designed for organizations that need reliable, scalable document processing without sacrificing transparency or auditability. LandingAI enables businesses to automate complex document workflows while maintaining trust, compliance, and operational efficiency.
