Complete list of free alternatives to Copyscape

PLEASE NOTIFY ANY INFORMATION THAT IS MISSING OR INCORRECT.

Plagiarism is one of the biggest challenges faced by content writers. Therefore, it is very necessary to check its content for originality.

One of the most used online tools for this purpose is Copyscape, which offers free and paid services. However, its free use has some limitations. The search is not as deep as that made by the premium or paid version and you can only search 10 results at once. Offline content can not be searched by copying and pasting with the free version. There are many other powerful features offered by the premium version that charges 5 cents per search.

There are some other tools available that can verify the duplicate content really well and can be used by anyone. Although there are some restrictions on the use, they are really good free alternatives to Copyscape. Here is the list!

The following can be used primarily for offline text:

  1. www.plagiarismchecker.com: a box is provided in which you can paste the text and search. This tool basically uses Google and Yahoo search engines. An option is provided to create a Google Alert, which sends you an instant notification when Google detects a copy of your work. To do this, you must send your email.
  2. www.duplichecker.com: with this tool, you can search for offline text simply by copying and pasting it in the box provided. The limit is 1500 words per search. Duplichecker yields results quite fast. You also have the option to upload a .docx or .txt file. Without registering, you can use this tool only 2 times a day.
  3. www.plagium.com: You can paste up to 25000 characters in the search box. In addition, advanced options can be configured, such as how strong the relevance should be, the pages on which the languages ​​should be searched and how the results should be displayed. You can perform a & # 39; Quick Search & # 39; with the free version, while the & # 39; Deep Search & # 39; It requires registration. Without registering, you can only use this tool once a day.
  4. www.dustball.com/cs/plagiarism.checker/ – Simply paste your text in the box provided. The results are shown for each sentence individually. You can perform two searches per day with free use.
  5. http://plagiarisma.net: this tool uses the Google search engines (only for registered members), Babylon and Yahoo. You can use Babylon or Yahoo at the same time. An option for the exact search is also provided. This tool supports more than 190 languages ​​and you can also check the content online by entering the address of the page. For offline text, you have the option to upload a file. PDF, DOC, DOCX, RTF, ODT, TXT and HTML formats are supported. The count of each sentence and the domains that contain it are shown in the results. For free use, you can use the tool only once per day.
  6. https://www.plagtracker.com/upload/ – You can paste a large amount of text in the box provided. (However, I'm not sure of the word limit). The results are processed quickly. You can only use this tool once a day without registering.
  7. www.articlechecker.com: Paste text in the box provided.
  8. http://paperrater.com/plagiarism_checker – Paste the text in the box. You must enter a captcha and accept the terms of service.

The following can be used only to verify online text:

  1. www.plagspotter.com: you can check if there are copies of your web page by entering its URL in the box provided. After pressing the search button, the results are displayed very quickly in two tabs. The & # 39; Font report & # 39; displays the list of URLs where a copy of your content exists together with the percentage of matching content. In the & # 39; Originality Report & # 39; tab, you can find duplicate content highlighted. When clicking on a particular line, the pages containing the line will be shown on the right. To use the batch search function, you need to register. I am not sure of the limit of pages that you can search at the same time, but I was able to check 8 pages (each page individually) at a time, after which the tool did not allow more checks.
  2. www.copygator.com: just enter the url of your blogpost and this tool will scan more than 2 million blog and RSS feeds to search for plagiarist content. Receive email notifications when duplicate content is found.
  3. www.virante.org/seo-tools/duplicate-content: this tool searches for the copies of the URL that you enter based on different techniques, such as headings and Google cache checking. It seems that this tool only informs if there is a duplicate page or not, but it does not recover the links from those pages.

The following tools require registration, so I have not yet verified how they work. Any information about these is very welcome.

When we use Google or Yahoo search directly to verify plagiarism, there are some limitations that we find. Queries are limited to 32 words on Google and 50 words on Yahoo. Also, if a copy of your work already exists and has not yet been indexed, it will not be detected immediately.
