PaperRater

Paraphraser.io

Best overall

For most everyday users, Paraphraser.io is the stronger choice because it offers a modern, fast rewriting tool with a free tier and clear pricing, while PaperRater feels outdated and lacks mobile support. PaperRater wins only if you specifically need automated essay grading and plagiarism checks without creating an account. The single biggest difference is that Paraphraser.io focuses on rewriting and summarization with a polished interface, whereas PaperRater is a legacy grading and grammar tool.
