tesseract.js

Why we included this project

Tesseract.js is a JavaScript port of the Tesseract OCR engine that runs in the browser through WebAssembly or on a Node.js server, so you can pull text out of images and scans without standing up a separate service. It recognizes more than a hundred languages. The worker API is the part that makes it practical: you create a worker once and reuse it across many images, which keeps repeated recognition fast. It also returns bounding boxes at the paragraph, word, and character level, which is handy for layout analysis or building your own extraction pipeline. Teams that want OCR embedded in a web app and would rather skip native dependencies on the backend will find this a straightforward fit.
