Common questions

Is Paraphrasing Tool by ParaphrasingTool.app better than QuillBot for students on a budget?

Yes, if you need unlimited paraphrasing for free and don't mind a cluttered ad-supported interface. But QuillBot's free version is more polished and integrates with your browser — you just have to work within its word limit.

Can I use either tool on my phone?

Neither has a mobile app. Both work in a mobile browser, but the experience is clunky. QuillBot's extension doesn't work on phones, so you're stuck with the website on both.

Which tool is easier to start using right now?

Paraphrasing Tool — just open the website and paste text. No signup, no limits. QuillBot requires a Chrome extension install and account creation to get the full experience.

Does QuillBot have a free plagiarism checker?

No, the plagiarism checker requires premium credits even on paid plans. Paraphrasing Tool includes a free plagiarism checker after rewriting, but it's less accurate than dedicated tools.

Which tool is better for professional writers?

QuillBot, because it offers grammar checking, tone analysis, and AI detection alongside paraphrasing — all accessible via a browser extension. Paraphrasing Tool is too basic for daily professional use.

QuillBot wins for daily writers with its browser extension and full toolkit; Paraphrasing Tool is the best free option for occasional, no-strings-attached rewording.

If you write regularly and want a tool that feels like a natural part of your workflow, go with QuillBot — it's worth the paid plan for the extension and extra features.
