Plagiarisma: Our Story and Contact Details



What Plagiarisma does

Plagiarisma is a free online plagiarism checker. Paste a draft, upload a file, or submit a URL, then review matching passages and the uniqueness score. Standard checks do not require an account. The report is a review aid for students, teachers, and editors. It is not a finding of misconduct, and it is not a substitute for an institutional system such as Turnitin.

A highlighted sentence can be a quotation, a reference title, a common phrase, or wording taken from a page. Open the source before you treat a match as copying. A low score does not prove the text exists nowhere else. Coverage is the web sources, books, and papers the checker returns, not every closed library.

Other tools

The same site includes an AI-text detector, a paraphraser, a grammar checker, a summarizer, a two-text comparison, an APA citation helper, and a free chat.

• The detector estimates whether prose looks model-generated. It does not name the product or prove who wrote the draft.
• The paraphraser changes wording. It does not remove the need to cite a source.
• The grammar checker flags spelling and punctuation. Accept a suggestion only if it keeps your meaning.
• The summarizer is a reading aid. Check numbers and caveats against the source before you quote it.
• The APA generator formats a reference from the fields you enter. It follows common APA 7 patterns and does not look up a half-remembered source.
• The chat is an assistant on Plagiarisma for outlines and drafts. It is not the official ChatGPT app and is not affiliated with OpenAI. Verify dates and citations elsewhere.

The checker reports support for 190+ languages. File uploads include PDF, DOCX, DOC, RTF, ODT, TXT, HTML, PPTX, XLSX, XLS, FB2, and EPUB.

Your text

Text submitted for a standard check is not added to a public database and is not shared with other users as a source. Do not upload passwords, exam keys, or client material you are not allowed to share. What is kept as a technical log, and for how long, is described in the privacy policy.
