Chunkr vs Haystack by deepset

Side-by-side comparison of pricing, features, and capabilities — 2026.

Tool A
Chunkr
Freemium

Chunkr is a document intelligence API that uses AI to extract structured content from complex PDFs, including tables, figures, mathematical formulas, and code blocks with high accuracy. Unlike basic PDF parsers that produce messy text, Chunkr preserves document structure, identifies semantic content regions, and outputs clean, structured data ready for RAG pipelines and LLM processing. The API handles hundreds of pages per minute and supports diverse document types including academic papers, financial reports, legal contracts, and technical documentation.
