Plagiarism Checking

Both Grammarly and Quillbot feature plagiarism-checking tools. Grammarly's longstanding presence in this domain instills trust among users, allowing the detection and replacement of potentially plagiarized content.

Quillbot's plagiarism checker, tailored for academic papers, employs its paraphrasing tool to rephrase duplicate content.

Quillbot boasts a summarizer tool for synthesizing lengthy passages and a citation generator to streamline referencing.

Additionally, Quillbot's SEO optimization feature aids in content planning for improved rankings.

While Grammarly excels in tone analysis and readability scoring, Quillbot's summarizer, citation generator, and SEO optimization cater to distinct needs.


Both Quillbot and Grammarly seamlessly integrate with popular software options, including internet browsers, Microsoft Word, and Google Docs.

Quillbot, however, necessitates content copying and pasting into the app for paraphrasing, adding an extra step in the writing process.
