Rewrites a sentence you cannot get right into several alternatives.
A paraphraser with tone modes — formal, simple, shorten, expand — plus a summariser, citation generator and grammar check sitting on the same page. It is genuinely useful for unsticking one clumsy sentence, and just as genuinely misused for laundering copied text, which is why universities now screen for it. Free mode limits how much you can rewrite at once.
