Framework for connecting LLMs with external data sources.
LlamaIndex offers LlamaParse, an agentic OCR service that turns complex documents—including messy tables, charts, images, and handwritten notes—into clean, LLM‑ready outputs. The platform parses 50+ unstructured file types, extracts structured data using schema‑based agents, and provides auto‑correction loops that recursively detect and fix errors, delivering high pass‑through rates on noisy scans. A free plan supplies 10,000 credits per month (about 1,000 pages) and includes layout‑aware parsing, structured schema extraction, and the ability to build and deploy end‑to‑end document agents. The service is positioned for document‑heavy industries such as finance, insurance, manufacturing, healthcare, and engineering, enabling use cases like financial due diligence, invoice automation, technical document search, and clinical research acceleration. LlamaParse claims to be up to four times cheaper than frontier labs and five times more accurate than other APIs, while also offering an open‑source LiteParse library for fast, local, token‑free parsing of PDFs, Office files, and images.
