In their own words
Plagiarisma
Plagiarisma is an originality checker that compares text with web sources, books and academic papers. Users can paste text, enter a URL or upload a document in formats including PDF, DOCX, RTF, TXT, HTML, spreadsheets, presentations and ebooks. Its homepage says the checker supports more than 190 languages. The service runs on the web and has a Windows desktop download listed as version 2.0 for.NET on Windows x86/x64. Desktop tools include plagiarism scanning, AI content detection, paraphrasing and APA citation generation. A Google Docs add-on offers checking, paraphrasing, summarizing and AI detection; its listing allows five free document scans per day, with paid features available by monthly subscription. A free plan is listed, including a Windows desktop checker at free. The company says it does not store private texts in public databases. Its FAQ says premium membership orders may be refunded within three days, while trial orders are not refundable.
Plagius
Plagius Desktop analyzes academic papers and other documents for possible plagiarism, checking the internet or local files. It supports Word, PDF, OpenOffice, PPT, HTML, RTF, and plain-text formats. Reports can identify suspicious phrases and sources, display URLs with similarity percentages, estimate suspected-plagiarism percentages, and show analysis-quality indicators; results can be opened in a browser or exported as HTML. Its V5 AI detector analyzes paragraphs in context and returns an AI-generation probability and confidence level. The site says it recognizes signals from more than 15 models, including Gemini 3.7, GPT 5.6, and Claude 5. Professional desktop plans add local and network-share searches, batch analysis, direct URL analysis, and file comparisons. The maker says desktop analysis is performed locally, but external searches may send text fragments, usually 7 to 13 words, to search engines. AI detection may send isolated paragraphs to Plagius servers, where excerpts are deleted within up to 48 hours. A free demo runs analysis but reveals only some results. Plagius One is browser-based and initially limited to invited users. Plagius Basic costs $6.90, paid once; its license lasts 30 days and is for one Windows computer. The maker cautions that automated results need manual review and cannot alone confirm plagiarism.
