About this tool
Check text against online sources to catch copied content before publishing. Paste your text and we'll scan it against billions of web pages to see if chunks appear elsewhere. Super useful for content writers, students, or anyone who wants to verify originality. We built this because free plagiarism checkers usually have tiny character limits or terrible interfaces. Ours handles longer content and shows you exactly which sentences match other sources with direct links. One thing: this is a premium feature since we're hitting expensive APIs to do deep web searches. Free tier gives you a limited number of checks per month. Also, it won't catch paraphrased content: only near-exact matches. For serious academic work, you might need something more advanced, but this covers most blogging and content creation needs.
