Simon Willison has created a browser-based version of LiteParse, an open-source tool from LlamaIndex designed for extracting text from PDFs. This new web version, built using PDF.js and Tesseract.js, allows users to process PDFs directly in their browser without needing a separate application. The tool employs sophisticated heuristics for spatial text parsing to maintain document structure and can optionally use OCR for image-based text, with a feature for visual citations using bounding boxes.
