Overview

LlamaIndex is a document intelligence platform centered on LlamaParse, an agentic OCR and parsing product for complex documents. It is designed to turn PDFs, Office files, images, tables, charts, handwritten notes, and other unstructured inputs into structured, LLM-ready outputs.

The site describes a broader workflow stack around parsing, extraction, splitting, classification, indexing, and document-agent building. It also offers LiteParse, an open-source local parser for teams that want offline processing with bounding boxes and structured output.

Features

Agentic document understanding

Turns complex documents into LLM-ready outputs through semantic understanding, with specialized handling for text, charts, tables, and other content types.

Auto-correction loops

Uses recursive checks to detect and fix errors automatically, which is aimed at improving pass-through on messy scans and multi-modal documents.

Structured extraction

Extracts structured data from unstructured content using schema-based, LLM-powered extraction agents without requiring training.

Flexible output formats

Supports parsing into multiple formats including Markdown, plain text, JSON, XLSX, HTML, tables, and annotated PDF, with output options that fit different downstream workflows.

Local parsing option

Provides local-only open-source parsing in LiteParse for PDFs, Office docs, and images, with bounding-box output and no cloud or LLM-token usage.

Document workflow platform

Includes parsing, extraction, splitting, classification, indexing, and workflow building for document-heavy teams.

Use Cases

Finance document analysis
Parse contracts, filings, and research documents into structured outputs that analysts can review or feed into downstream workflows.
KYC and AML processing
Extract, verify, and route identity and transaction documents for KYC and AML workflows.
Audit and back-office automation
Automate handling of invoices, claims, and audit materials where consistent extraction and traceability matter.
Multi-step document agents
Build document agents that read complex sources and take actions such as routing, validation, logging, and notification.

Pros and Cons

Pros

Handles complex layouts, tables, charts, images, and handwritten text.
Offers both cloud-based LlamaParse and a local open-source LiteParse option.
Supports multiple downstream outputs, including Markdown, JSON, XLSX, HTML, and annotated PDF.
Includes workflow features beyond parsing, such as extraction, split/classify, indexing, and agent building.
Provides enterprise options such as VPC deployment, security controls, and support tiers.

Cons

The site does not publish a complete feature-by-feature integration list on the provided pages.
Some capabilities are tied to credit usage or specific plan tiers, so cost depends on the chosen parsing or extraction mode.

How does credit usage work for parsing?

The pricing page says parsing or extraction costs depend on the mode and options selected. Basic parsing can be as low as 1 credit per page, while layout-aware agentic parsing with LLMs or VLMs costs more for higher accuracy.

Can LlamaParse be deployed on premises?

Yes. The pricing page describes SaaS hosting on a secure cloud tenant, with an option for enterprise deployment in private VPCs across cloud providers.

What outputs and file types does it support?

The pricing page lists output options including Markdown, plain text, JSON, XLSX, HTML, tables, and annotated PDF, and it supports 130+ file formats.

Who is LlamaParse for?

The site positions LlamaParse for teams that need document parsing, extraction, indexing, and retrieval over complex documents, especially where layout, tables, charts, or handwritten notes matter.
