LlamaIndex

LlamaIndex is an API and web platform for developers and enterprises that converts complex documents (PDFs, scans, images, spreadsheets, handwritten forms) into structured, AI-ready data and automates multi-step document workflows.

Key capabilities include:

• LlamaParse for multimodal, layout-aware parsing across 90+ file formats, preserving structure such as headers, columns, footnotes, and multi-page tables, plus support for embedded images and handwritten notes.
• LlamaExtract for schema-driven extraction that produces structured outputs with confidence scores and page citations for traceability.
• Agentic OCR that uses LLMs and vision models to interpret semantic context, paired with multi-pass validation loops to detect and correct OCR errors.
• Workflows for event-driven, async-first orchestration, enabling stateful pipelines that can run steps in sequence, loop, or parallelize (designed to integrate with modern Python apps).

Pricing: Free plan available (includes 10,000 free credits per month, approximately 1,000 pages); other tiers are not specified.

Notable for combining document parsing, extraction, indexing for RAG, and workflow orchestration in modular components, with an emphasis on layout preservation and verifiable outputs for enterprise document automation in domains like finance, insurance, manufacturing, healthcare, and legal.
