The single biggest difference: QuillBot is a full writing suite; ParaphrasingTool.us is a focused paraphraser.

Common questions
Yes, if you need to paraphrase in languages like Spanish, French, Mandarin, or Arabic, ParaphrasingTool.us supports over 30 languages. QuillBot's paraphrasing is primarily optimized for English.
Neither has a dedicated mobile app. Both work through a mobile browser, but QuillBot's Chrome extension does not work on mobile browsers. For phone use, you'll be typing or pasting text into the website.

Both are easy, but QuillBot's Chrome extension makes it even simpler: highlight any text on a webpage, click 'Rephrase,' and it's done. ParaphrasingTool.us requires you to visit the website and paste or upload text.
QuillBot is the better all-around choice for most people; ParaphrasingTool.us is a solid free paraphraser for multilingual users who don't need extra features.
