Document ETL platform for parsing and chunking enterprise content.
Unstructured is the leading open-source platform for converting messy enterprise documents — PDFs, Word files, PowerPoint decks, HTML pages, images, emails — into clean, chunked text ready for embedding and retrieval. It solves the unglamorous but critical problem that most enterprise data isn't neatly formatted text; it's trapped in complex document layouts with tables, headers, footers, multi-column formats, and embedded images.
Unstructured's core library provides a universal partition() function that detects document type, applies the appropriate parser (including OCR for scanned documents), and outputs structured elements: titles, narrative text, tables, list items, and images, each classified by type and position within the document hierarchy. This element-based output is significantly more useful than raw text extraction because it preserves document structure.
CrewAI is an open-source Python framework for orchestrating autonomous AI agents that collaborate as a team to accomplish complex tasks. You define agents with specific roles, goals, and tools, then organize them into crews with defined workflows. Agents can delegate work to each other, share context, and execute multi-step processes like market research, content creation, or data analysis. CrewAI supports sequential and parallel task execution, integrates with popular LLMs, and provides memory systems for agent learning. It's one of the most popular multi-agent frameworks with a large community and extensive documentation.
