Plagiarism is a very serious problem that involves copying content like blog posts and academic work from other sources or websites without appropriate citation. Search engines like Google do not like plagiarised content. If you happen to use copied information on your site whether intentionally or unintentionally, you could easily compromise your page ranking and reputation. This is where plagiarism checker softwares come in and help you to confirm the authenticity of your content. You only need to paste or upload your content into the software and then run the plagiarism check.

Best Free Plagiarism Checker

Although we reviewed Grammarly just a few months back which checks for plagiarism, but the feature is enabled only in the paid plan, hence we can’t really say Grammarly is a free plagiarism checker. But nonetheless, we have rounded up the best free plagiarism checker solutions to help you get the most appropriate one for your requirement.

 

1 Unicheck

An online plagiarism checking tool which packs a couple of features but with a limit of 500 words. You can directly copy/paste your text or choose to upload txt, doc, pdf, odt, or xls file. You get an online report showing the results of the check. This helps because you can easily see the matches. If you need to check more documents for plagiarism or have longer documents, then you can directly buy from the pricing page.

Pros: Unicheck is free to use for up to 500 word count

Cons: Only 500 words are free to check, Payment is acceptable via PayPal only.

 

2 Copyleaks

Everyone has heard of Copyleaks, they are the forerunners in catching copy/pasters. Best part is that their service is free for most part. You can scan content up to 10 pages a month. If you require more checks, then perhaps purchasing credits is a better idea. The links to the different plans: Education Plans, Businesses Plans, Academic API plans, Businesses API plans, Websites API plans. All plans are subscription based as well as prepaid but do note every page is considered to hold 250 words, if you check 252 words, this will be counted as two pages. Copyleaks support all common file types as well as HTML, rtf, ppt, epub, gig, png, jpeg, bmp and many more. They have an for iOS as well as Android platform. You can buy plans via credit cards.

Pros: Free to use for up to 10 pages a month, many file types supported.

Cons: No refunds.

 

3 DupliChecker

One of the best free services that you can use to check for plagiarism is DupliChecker. It does not even require registration to be able to use it. Nevertheless, since it is free, you are limited to run a plagiarism check only once per day. To run a plagiarism scan, you are supposed to copy the desired document and paste in the text box or simply enter the URL link to the content you want to check. Once the scan is complete, you are going to see links to any plagiarised content. When you click the links, DupliChecker will redirect you to where the copycats are.

Pros: DupliChecker is free to use and comes with extra free functions like spell checking.

Cons: You are limited to one check daily as a free user and ensure that the text is under 1,500 words.

 

4 Small SEO Tools Plagiarism Checker

Small SEO Tools refers to a hub of some of the best free tools for analysing the SEO status of a website and optimise it better for search engines. One of the available tools that you can use for free is the plagiarism checker. While it is regarded as a very reliable source of checking for plagiarism, users are limited to less than 1,000 words. Once you paste your text into the text box or upload a Word or Text file, the online software will then scan the entire internet to check for plagiarism. If it discovers any plagiarised content, it highlights it in red, and this helps you make the necessary changes to maintain authenticity.

Pros: Easy to use to either check plagiarism or grammar.

Cons: Since it is free, there are numerous adverts with questionable offers for improving your website SEO.

 

5 Plagiarisma

Upload, copy and paste or just type the article that you want to check for plagiarism into Plagiarisma’s user-friendly software. It will run a thorough scan and show you if your text is authentic or not, listing the websites that contain the matching versions. In addition to free plagiarism checks, the site also features several useful tools. This includes several methods to input word files, inbuilt spellchecker and the feature of checking for plagiarism from a web URL. Pro versions are available with accounts ranging from $5 per day for 100 searches to $50 for six months.

Pros: Simple interface to navigate and also generally easy to use.

Cons: A similarity checker and article rewriter mean that some of the features of Plagiarisma seem to be promoting plagiarism.

 

6 ProWritingAid – Paid

On the expensive end, but worth the dime. ProWritingAid is an essential tool for writers but slightly better than Grammarly. Their plagiarism checks cost $10 for 10 checks, $40 for 100 checks, $120 for 500 and $200 for $1000 checks. With a 14-day money back guarantee, you are safe to check out this service.
