3 Best Free Plagiarism Checker Software
I tested about ten There are several ways plagiarism checkers on the Internet to offer you only those I consider to be the most effective. Note that the two israel phone number library tools I used to use are not included in the list below. Indeed, their analysis capabilities were no longer competitive and the features offered were limited. Here are the criteria used to sort them:
- ease of use;
- length of text in free version;
- paid options ;
- additional features ;
- speed of control;
- relevance of the results.
To ensure the accuracy of the proposed results, I analyzed a text published 6 months ago on the SEOQuantum blog . Sometimes, the online plagiarism detector displayed a similarity score lower than 80%, which of course proves a malfunction of the tool. Discover the top 3 free anti-plagiarism software !
1. PrepostSEO
PrepostSEO is a plagiarism checker that can analyze up to 1,000 words per text in the free version. However, several paid subscriptions are available to extend the plagiarism check to more than 5,000 words (starting at $50 per year). In addition, this allows you to remove the numerous ads that penalize the site’s user experience. Note that if you are using the free software and have an ad-blocking browser extension , you must disable it to access the tool.
By analyzing the text already published on our blog, I obtain a score of 100% similarity (it is the only one of all the tools tested!) in a very reasonable time (about one minute). Moreover, despite the interface being partially translated into French , it is very easy to use . However, remember to select “other language” during your plagiarism check to ensure the quality of the results offered.
To compare your content, you can simply copy and paste your text, drop a file, or upload it from Google Drive . However, you can’t analyze from a URL, which can slow down the analysis slightly if your content is already online.
The website also offers efficiency and profitability in every shipment a paraphrasing tool . Unfortunately, the test run for a French text turned out to be disastrous. Indeed, the reworded words were replaced with random synonyms and the content became completely illegible. They thus guarantee a unique text, which is not surprising given the deplorable editorial quality provided by this tool!
2. Duplicate Checker
Dupli Checker is a tool that has been fully translated into French , making it very easy to use. This free anti-plagiarism software allows you to analyze up to 1,000 words without a subscription , which is already good for knowing if your content is unique. Since monthly usage is not limited, you can divide your text into several thousand words to check it all. However, if your content is extremely long, a large choice of paid plans is available (up to 25,000 words analyzed per text). On the other hand, the offers are so numerous and poorly explained that I cannot give you an exact price.
The plagiarism check turned out to be very good. With a similarity score of 96% , I consider the tool to have done its job well and to meet the user’s needs. However, the analysis time was quite long (about two minutes), which can quickly become annoying if you have a lot of plagiarism tests to perform. In addition, the repeated captchas and the untidy interface penalize the overall experience.
To check content, you can either paste your text directly or upload a file . You can also check any web page for plagiarism by simply inserting its URL .
Additional tools are also available in the free version. You can perform a grammar check or reformulate your content to make it unique. The grammar analysis was satisfactory, including comments regarding repetitions. However, the reformulation of the plagiarized text was catastrophic (the terms were replaced with English words!). It therefore appears that this option is not yet available in French.
3. Search Engine Reports
Search Engine Reports is free to use and allows you to analyze a text of 1,500 words for plagiarism . However, there is no paid version that allows you to increase the number of words to be checked. In any case, the software is very easy to use and fully translated into French.
The plagiarized article used for the clean email test received a score of 96% , which is very relevant. However, it took almost four minutes to access the report, which is very slow compared to the other tools tested. But since the result is very consistent, I suggest you try this tool anyway.
You can paste your content directly, add a file from your computer, or upload it from Dropbox, and enter the URL of the web page you want to analyze. Note that you can exclude up to 5 URLs from the analysis if necessary .
Another interesting point is that there are many other free SEO tools available as a complement (use the menu on the right). In addition to plagiarism detection, you can reword a text (maximum 2,000 words) or check grammar . The latter proved to be consistent and fast, while rewording took several minutes to display a disappointing and unusable final result.
