This forum is for the app “Optical character recognition”.
Nextcloud OCR (optical character recognition) processing for images with tesseract-js brings OCR capability to your Nextcloud. The app uses tesseract-js in the browser in order to process images (png, jpeg, tiff, bmp) and saves the output PDF file to the source folder in nextcloud. That for example enables you to search in it.
