Review Results
Get an overall originality score, matched source URLs with similarity percentages, and per-sentence analysis highlighting flagged passages. Use the Humanize feature to rewrite flagged text automatically.
A plagiarism scanner needs to be fast, thorough, and clear in its results. Writers, editors, and educators don't have time to wait for batch processing or interpret ambiguous percentage scores. They need to paste text, scan, and immediately understand which parts are original and which need attention. Speed and clarity are what separate a useful scanner from a frustrating one.
Coda One's Plagiarism Scanner delivers results in seconds. Paste your text, click scan, and get three layers of analysis: an overall originality score showing the big picture, matched source URLs showing where content overlaps with existing web sources, and a per-sentence breakdown showing exactly which sentences triggered the match. The color-coded sentence view -- green for original, red for flagged -- lets you identify problem areas at a glance.
The scanner works for any type of text content: academic papers, blog posts, marketing copy, product descriptions, social media content, and professional documents. Whether you're a student checking an assignment, an editor screening submissions, a content manager verifying freelance deliverables, or a marketer ensuring ad copy is original, the scanning process is the same: paste, scan, review. The tool handles texts up to 300 words on the free tier, with higher limits available on paid plans.
