Ocrad.js is a JavaScript port of the GNU Ocrad optical character recognition engine compiled with Emscripten. It brings text recognition directly into web applications without requiring a remote OCR service. Local processing can reduce network latency and support offline-capable applications. Possible uses include extracting text from images, browser-based note tools, image indexing, and experimental handwriting input. The repository includes the compiled library, source material, examples, a browser demo, and worker support. Its recognition engine is rule-based, so accuracy can vary substantially with character quality, spacing, weight, and input preparation.
