About This Tool
The Plagiarism Text Comparison tool lets you paste any two pieces of writing and instantly see how similar they are. The analyzer breaks each text into individual words and multi-word phrases, then cross-references them to produce a precise similarity percentage. Whether you are checking student submissions, comparing drafts, or auditing content originality, this tool delivers clear, actionable results in seconds — no account or internet connection required.
Matching phrases are highlighted directly inside both text panels so you can see exactly where the overlap occurs. Color-coded highlights make it effortless to spot copied sentences, paraphrased passages, or shared vocabulary clusters. Alongside the visual highlights you get a concise statistics panel showing total similarity percentage, the number of matching word tokens, and the unique-word counts for each individual text so you can assess originality at a glance.
Because the comparison runs entirely in your browser using JavaScript, your content never leaves your device. This makes it ideal for sensitive documents, proprietary content, or any situation where privacy matters. The tool handles texts of any length — paste a short paragraph or an entire essay and the analyzer adjusts automatically. Use it as a first-pass originality check before submitting to a paid service, or simply to compare two versions of your own work side by side.
