Plagiarized content promises adverse consequences for students, writers, and website owners.
For students, plagiarism might lead to low grades, automatically failing a course, academic probation, or even expulsion.
For business owners, an instance of plagiarism might be a copyright violation that results in fines and lawsuits. When plagiarism rises to the point of duplicate content (copying entire blog posts and web pages), it can also affect how your site ranks.
Google will have to choose between the two similar versions and remove one from search engine results. This will result in the deindexed version missing out on the opportunities that come with a strong rank on search engine results.
The good news is that there are multiple plagiarism checkers out there, most of which you won’t have to pay a dime for. Whether you’re a teacher, student, writer, or website owner, here are five free plagiarism checkers you can start using today:
1: SmallSEOTools
SmallSEOTools is a swiss army knife for website owners and writers. Besides offering a free plagiarism checker, it features various website optimization tools, including a:
- Spell checker
- Backlink and keyword analytics tool
- Text case changer
- Article rewriting tool
The SmallSEOTools free plagiarism checker will allow you to scan up to 1000 words of content as many times as you like.
You can upload your content from Google Drive, Dropbox, or your local drive. It supports multiple document formats including .rtf, .pdf, .docx, .txt, and .od. Alternatively, you can paste a URL into the site to scan it for plagiarism.

Here’s what Avishek Maity had to say about this tool:
I have to go through multiple assignments on a daily basis, ensuring their authenticity is a tough job to accomplish. The detailed reporting option offered by SmallSEOTools Plagiarism Checker eases out the entire process.
2: Plagiarismdetector.net
Plagiarismdetector.net is an amazing tool for writers, teachers, students, and website owners. Its free version allows you to scan up to 1,000 words of content for plagiarism at a time, and there are no limits to how many times you can run the scan.
Its paid version, however, has no word limit. Unlike the free version, the premium version is also ad-free. The pro version is divided into three price plans: student ($20/month), institute ($40/month), and enterprise ($80/month).
The tool looks for plagiarism through word choice, matching phrases, and lexical frequencies.
It allows you to upload content in different formats including .txt, .doc, and .docx. You can also upload text directly from Dropbox or scan content straight from a URL.
Its biggest downside is the 1,000-word limit per search. This limit can complicate how easily authors and teachers can scan complete content for plagiarism.

5: Plagiarism Checker X
Plagiarism Checker X is ideal for students, teachers, writers, and business owners. Unlike the other plagiarism detectors on this list, it’s a tool that you’ll have to download onto your device.
The software features a side-by-side comparison, content similarity detection, and bulk cross-comparison. This last perk makes it ideal for teachers looking for plagiarism between students’ work.
Plagiarism Checker X supports plagiarism scans in seven languages, including French, German, English, Spanish, Italian, Portuguese, and Dutch. You can also scan for plagiarism using multiple file formats, such as .pdf, .doc, and .rtf. The free version allows up to 30 daily free scans, each one capped at 1,000 words.
The tool also offers two lifetime premium versions: a professional plan at $39.95 and a business plan at $147.95. The business plan includes all professional plan features with the addition of four more users, branding reports, priority support, and spreadsheet support.
You’ll only need to pay a small yearly maintenance fee after this.
Its biggest downside is that it’s only compatible with Windows. Mac users will have to look for alternatives.
