I built a new tool: https://tools.simonwillison.net/ocr - it runs OCR against images and PDFs entirely in your browser (no file upload needed) using Tesseract.js and PDF.js

I wrote more about the tool and how I built it (with copious amounts of Claude 3 Opus and a little bit of ChatGPT) here: https://simonwillison.net/2024/Mar/30/ocr-pdfs-images/

OCR PDFs and images directly in your browser

Something I really like about this tool is that the entire thing is 226 lines of combined HTML, CSS and JavaScript (plus the PDF.js and Tesseract.js dependencies, loaded from a CDN)

The code is a little untidy but at 226 lines it honestly doesn't matter https://github.com/simonw/tools/blob/9fb049424f4ec8f8ffb91a59ab7111cad56088fc/ocr.html
