LlamaIndex’s centre of gravity is LlamaParse, which reads documents that defeat ordinary optical character recognition: tables split across pages, charts, embedded images and layouts that were designed for a human eye rather than a parser.
That step is the one that decides whether everything downstream works. An agent reasoning over a badly parsed table is confidently wrong, and no amount of model capability recovers information the parser dropped. The framework for building agents and workflows sits on top of it.
Pricing is published, starting from a free tier and running through $50 to $5,000 plans with credit-based usage. Credits make spend hard to predict when volume varies, and genuinely complex documents still want spot-checking against the source.
