Free Online Plagiarism Checkers<\/h2>\nThere is a great choice of free plagiarism checkers on the internet, so if you have to check your text fast, use one of the following services. Normally, you don\u2019t have to sign up, just type in the text and let the program compare it with thousands of sources available online. It is useful to not only check the uniqueness of the text but also to add citations. Moreover, most programs offer additional features such as grammar and spell checkers, SEO tools or formatting your text to APA\/AML style. However, free tools usually have limitations in terms of the text volume, so if you have a long-read article or constant inflow of content to check, it\u2019s better to buy a subscription.\n

Dupli Checker<\/a><\/h3>\n
\n
\"Dupli\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure><\/div>\n\nThis is a free-of-charge tool available as a web editor. You can type a text in the interface of the program, upload a file or indicate a webpage URL. The plagiarism check is very fast. It takes only a few seconds to scan a text and detect if there is any convergence with other texts over the internet. It is possible to use the tool without registration, but you\u2019ll only be able to check 1,000 words per search with one search per day. However, upon signing up on the platform – which is totally free – you\u2019ll have 50 free searches per day.\n\nApart from plagiarism checker, the program also has a paraphrasing tool, keyword position checker, reverse image search, word counter, and other useful SEO tools.\n

Copyleaks<\/a><\/h3>\n
\n
\"Copyleaks\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure><\/div>\n\nCopyleaks has both free and premium subscriptions.

Small SEO Tools<\/a><\/h3>\n
\n
\"Small\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure><\/div>\n\nThis is a perfect platform for checking small texts. It is free and has a lot of additional features like text content tools (Word counter, Article rewriter, Grammar and spell checkers), image editing tools, keyword and backlink tools and more. Plagiarism checker is one of the numerous features available on the platform. You can type in a text, upload a document or indicate an URL. The number of searches is not limited, but one text cannot exceed 1,000 words (which equals to a four-page document). Furthermore, if you change the word order in the sentence, the platform won\u2019t detect plagiarism at all, so it cannot be used as a self-sufficient tool.\n\nSmall SEO tools claim to offer an excellent alternative for paid services because the company believes that internet marketing should be available for anyone. With this program, you\u2019ll be able to access a big number of search engine optimization tools for free and make your text rank higher among the search results.\n

Search Engine Reports<\/a><\/h3>\n
\n
\"Search\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure><\/div>\n\nThis is another free resource, but it is only recommended for checking small texts or even a few sentences due to its algorithm. Every phrase in your text will be checked separately which decreases the chances to detect plagiarism correctly. Furthermore, sentences that are considered copied are not highlighted. The system leaves you with a number of links to the resources in which Google search found similarities to your text, so you\u2019ll have to check manually what exactly coincides with other web pages. Also, you\u2019ll face a lot of advertisements on the website.\n

Quetext<\/a><\/h3>\n
\n
\"Quetext\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure><\/div>\n\nQuetex claims to be the number one plagiarism checker software for over two million students, teachers, and professionals worldwide. However, you\u2019ll be able to take advantage of its free services for only three plagiarism checks with up to 500 words per check after you sign up on the website. The monthly subscription is not that costly in comparison to other platforms – its price is about $10. There are some additional features like a Citation Assistant, and an opportunity to check PDF files as well. According to the website, documents checked on Quetext are not added to its database.\n

Prepostseo<\/a><\/h3>\n
