LlamaIndex

LlamaIndex parses and extracts complex documents and lets teams build AI-powered agents. Its agentic OCR handles layout-aware parsing and structured extraction of defined schemas, and auto-correction loops detect and fix errors automatically, even on messy scans and multi-modal documents.

LlamaIndex has a limited free plan that includes 10,000 free credits per month, about 1000 pages. Paid plans start at $50 per month, as published by the vendor in September 2026, and add more than the free plan's limited features and credits.

The vendor claims LlamaIndex is 4x cheaper than frontier labs and 5x more accurate than other APIs. The reviewer says it excels at parsing complex layouts, with recursive checks that deliver high pass-through rates on messy scans.

The reviewer says LlamaIndex does not handle very simple document types well without manual setup. It also does not support custom training, although its schema-based extraction agents need no training, and the free plan's features and credits are limited each month.

Toolio lists LlamaIndex as best for engineering and R&D teams and not for very simple document types. It runs on the web and through an API, supports building and deploying end-to-end document agents, and holds a Toolio score of 4.0 out of 5.
