Chunkr

Chunkr is an open-source document intelligence platform that turns complex documents (PDF, Office, images) into RAG- and LLM-ready data. The Chunkr Cloud API at api.chunkr.ai performs layout analysis, OCR, segmentation, and chunking, and runs proprietary in-house vision models; the AGPL-3.0 open-source release (lumina-ai-inc/chunkr) can be self-hosted via Docker.

Chunkr publishes 3 APIs on the APIs.io network: Files API, Health API, and Tasks API. Tagged areas include Document Parsing, OCR, Chunking, RAG, and Document Intelligence.

Chunkr’s developer surface includes authentication, documentation, and 9 more developer resources.
