doesn't generate searchable pdf. Update: OCR was enabled, maybe I didn't realise it was a manual step, or that you need to do it twice the first time, either way on best quality it didn't do a good job of it... it also doesn't detect document edges very well and AutoCAD doesn't seem to work, had to manually click button.

It does if you enable and OCR the document first. If you have any issue please open an issue at https://github.com/Akylas/OSS-DocumentScanner/issues

I have tested a few free OCR scanners from play store. This had by far the best results for a free OCR scanner. The results from this OCR app were the best of 5 i tried. Additionally there are no incredibly annoying ads to put up with with this one which is another bonus!!
