How to annotate scans for NLP

Your problem: you have a bunch of scanned images or PDFs but cannot make use of it because you cannot even select the text. Your solution: you just need to OCR your scans (saving the results into text-embedded PDFs) and then to upload those into tagtog. From there on, you can annotate (by just highlighting the text) and export your valuable data into machine-readable JSON. This is thanks to the Native PDF annotation built in tagtog. All your text selections can then be downloaded in JSON, which you can use to train your ML models!
