Common questions

Is PaperRater better than Paraphrase Tool for students?

For students who need automated essay grading and quick grammar checks without signing up, PaperRater is better. For students who need to paraphrase sources or avoid plagiarism, Paraphrase Tool is the stronger choice.

Can I use these tools on my phone?

Neither tool has a dedicated mobile app. PaperRater's website is clunky on phones; Paraphrase Tool's web interface is more responsive but still not ideal for small screens. Both work best on a desktop or tablet.

Which tool is cheaper for regular use?

PaperRater's annual plan is very affordable if you only need grammar and plagiarism checks. Paraphrase Tool's paid plan starts at $4.99/month, which is reasonable for daily rewriting, but the free tier is too limited for regular use.

Can I upload a PDF to PaperRater?

No, PaperRater does not support PDF uploads. You can only upload .doc, .docx, .rtf, and .txt files. Paraphrase Tool does accept PDFs.

Which tool is better for non-native English speakers?

Paraphrase Tool is much better because it supports over 100 languages and offers translation alongside paraphrasing. PaperRater is English-only.

Do these tools integrate with Google Docs or Microsoft Word?

Neither tool offers direct integrations with Google Docs or Word. You have to copy and paste text or upload files manually.

PaperRater is a no-frills academic checker; Paraphrase Tool is a versatile rewriting companion for everyday writing tasks.

If you're a student who just wants a quick grammar grade and plagiarism check without any fuss, PaperRater is fine for occasional use. But if you write regularly, need to rephrase content, or work in multiple languages, spend the few dollars a month on Paraphrase Tool — it's far more useful day to day.
