A few benefits of plagiarism checker software for small businesses include:  - **Protects academic integrity:** By using plagiarism checker software to verify the originality of written content, educational institutions are able to check if students are creating original responses to assignments and haven’t copied from sources on the internet or from other students. This ensures that students are being held to the highest levels of academic standards and provides a deterrent to potential violations of the institution’s policies on plagiarism. - **Saves validation time:** Plagiarism checker software allows teachers, professors, and editors to quickly check the originality of submitted documents. Instead of manually comparing a document across an infinite range of documents to find the incidence of plagiarism, the software quickly compares content against databases of documents and webpages and informs the user of its originality in seconds. - **Avoids copyright infringement:** According to the [U.S. Department of Justice](https://www.justice.gov/archives/jm/criminal-resource-manual-1852-copyright-infringement-penalties-17-usc-506a-and-18-usc-2319), the penalty for duplicating intellectual property without citation can be as much as $250,000. By comparing content across a database of copyrighted work, plagiarism checker software will alleviate the liability of duplicating material, whether it was done intentionally or otherwise. * * * ## Typical features of plagiarism checker software Depending on the plagiarism checker software you choose for your business or institution, different features may be more applicable than others. Here are the most common features of plagiarism checker software: - **Content scan:** Scan written content within documents, files, or websites to quickly validate whether it is original or duplicated material. - **Analytics and reporting:** Create reports from content scans that detail the frequency and severity of content similarities so writers can quickly see what needs to be reauthored. - **Text similarity detection:** Detect similarities between other existing documents or sources. - **Multiple file format support:** Compare similarities in content across a wide range of file formats, such as Doc, Docx, PDF, HTML, etc., without having to convert files to the same format. - **Filterable searches:** Narrow down your plagiarism searches by specifying the types of content to compare your source material and selecting from a variety of academic and professional databases. - **Side-by-side comparison:** Compare two documents or content pieces side by side to see a detailed view of which part has been duplicated. - **Source database integration:** Access databases containing existing files, documents, journals, books, or other content to expedite searches across multiple sources of information. - **Multi-language support:** Compare authored documents with those written in other languages to verify that intellectual property hasn’t been copied from a translated source. * * * ## The cost of plagiarism checker software Most products in this market are priced on a per month basis, billed annually. Pricing can be divided into three pricing tiers based on the starting prices:  **Price ranges\*:** - $6 - $8 - $8 - $13 - $13+ _\*The pricing included is for the entry-level/lowest-priced offering found on vendor websites as of April 6, 2022. These ranges correspond to the 25th, 75th, and 100th percentiles of pricing information gathered from vendor websites of sample products._ * * * ## Considerations when purchasing plagiarism checker software With so many types of plagiarism checker software on the market, it’s important to choose an offering that provides the right features needed for your institution’s needs. Here are a few things to consider when purchasing plagiarism checker software: - **Cost of ownership:** Many plagiarism checker software packages provide free trials, allowing users to test the software’s feature set before purchasing. After the trial period, the software can be purchased either after a one-time fee payment or as a monthly subscription service. Consider the future needs of your business and which purchase option works right for you. - **Grammar and writing tools:** In addition to plagiarism checking features, many software packages in this field offer additional features that validate grammar and spelling in real time. If this is already provided through your current desktop publishing or word-processing software, you may end up paying for features that you don’t need. - **Vertical market and language support:** Before purchasing plagiarism checker software, consider the types of documents you will be comparing. Some packages are designed to validate content originality against specific vertical market databases, such as the academic or legal fields. Other offerings access databases that include source content in multiple languages. * * * **Sources** Products evaluated for the pricing calculation were taken from Capterra’s [plagiarism checker software directory](https://www.capterra.com/plagiarism-checker-software/), sorted by the number of reviews. The pricing ranges exclude freemium versions of the products. The features highlighted were identified based on their relevance and the percentage of products in Capterra’s directory that offer them.  The following sources were used for this document:  1\.
