Quick and easy to handle. I work with big report (100-200 pages) full of chemical formulas and graphs. From non-editable PDF image files, I could take the text as a whole. For long tables of numbers it's magic (no fault)! For graphic or chemical formulas inserted in the text that is not there yet (note: they are recognized but little or exploitable). An extraordinary time savings; for those who do not want to retype the text tool is inescapable: under misspellings (since we do not usually retype text that has already been fixed beforehand). When you have many documents like this, it changes life, and what seemed to you a mammoth task becomes very easy and affordable it! Save time, gain in quality, thus earning money. Note that it is possible to create different dictionaries (eg technical) based on the documents that are to be treated and thus be given specific technical bases in the recognition of specific documents. This type of software can be quickly profitable. Ah, if anything, I also work with documents in English: no problem. One more effort to better isolate the graphs and formulas (or others) to have them in a format (ie in graphical format) and this would be the perfect software.
