Reader
Reader is an AI data ingestion pipeline and web content parser designed to convert websites and documents into clean markdown for use with large language models. It functions as a headless browser content extractor and web-to-markdown converter, transforming URLs and PDF files into structured text formats while removing irrelevant web clutter.
The system optimizes retrieval augmented generation by acting as a search optimizer that retrieves web results and applies re-ranking to improve context relevance. It further enhances content accessibility by using vision models to generate descriptive captions for images and creating vector embeddings for semantic retrieval.
The tool provides broad capabilities for document conversion, web content extraction, and data preprocessing. These include headless browser rendering for JavaScript execution, multi-format conversion of office documents, and bucket-based content caching to reduce latency.
The conversion engine can be deployed as a self-hosted container including all necessary headless browsers and document processors.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
