Comet Lab Atlas

A toolkit and API for turning PDFs, office files, and emails into clean, chunked text for AI.

Unstructured handles the unglamorous first mile of any RAG project: taking the formats real businesses run on — PDFs, Word, PowerPoint, HTML, email — and producing structured, model-ready elements.

It comes as an open-source library and as a hosted API and platform that adds connectors and scale. Either way, the job is the same: get from a folder of mixed files to clean chunks without writing a parser per format.

Where it's ideally used

The right tool when source content spans many file formats and you need one consistent ingestion path into a RAG pipeline.

Where it doesn't fit

More than you need when every document is the same simple, well-structured format that a single targeted parser handles.
