tesseract-ocr? You can download it via apt or something similar.

paperless-ngx has built in ocr but I don't think it would fit your needs

[–] t1nk3rz@alien.top 1 points 1 year ago

I will check it up

You could spin up paperless-ngx. Or use pdf24 creator. Beware paperless consume will delete the file.

I used paperless-ngx before and it works pretty good.

I will check it up, i have Stirlingpdf and I see it also has ocr support

I'm not sure I understand you correctly. Do you want to apply OCR to PDFs or to Screenshots?

For PDFs there's the excellent ocrmypdf which paperless-ngx uses under the hood.

Nextcloud AIO (all-in-one) comes with full text search installed, which brings tesseract to nextcloud. so you can let tesseract-ocr run over all documents and then they will be searchable with Elasticsearch.
