I have been loking for a few weeks for affordable app, which can paraphrase, summarize text and has in-built plagiarism checker.
Even if now is last funcionality (paraphrasing tool) under maintance, I think it is due improvements of this tool. But I tried it before maintance and it seemed, it would be very useful.
What I would like to be improved:
1. More tones in paraphraser
2. Possibility of paraphrasing from link (same like summarizer)
3. ...even if is this app good and suits to my needs, I would be happy, if it is continuing of improving in future.

So or so, I recommend this app, it works fine in my (Czech) language very well too. I am considering to buy 1 more code yet.
