What is a plagiarism checker and how does it work?
A plagiarism checker is an online tool that analyzes your submitted text to detect any instances of copied or duplicate content. Our tool uses AI to break your text into sentences, analyze the structure and phrasing, then determine what percentage of the content is unique versus potentially copied — giving you a clear, sentence-by-sentence breakdown within seconds. It checks for direct copying, paraphrased content, and common phrases that may indicate non-original writing.
Is this tool completely free to use?
Yes, absolutely! Both the Plagiarism Checker and Grammar Checker are 100% free with no hidden fees, no credit card required, and no account registration needed. You can check up to 2000 words per search completely free of charge. There are no daily limits on the number of checks you can perform. Simply paste your text and click either button — no strings attached, no premium upsells.
Is my content safe when I use this tool?
Your content’s privacy and security is our top priority. We guarantee that your submitted text is never stored, indexed, or shared with any third parties. As soon as the check is complete, your text is automatically and permanently cleared from our system. Our strict no-data-retention policy means you can safely check even sensitive or confidential content with complete peace of mind.
What does the Grammar Checker detect?
Our AI-powered Grammar Checker analyzes your text for four types of issues: Grammar errors (subject-verb agreement, wrong tense, sentence structure), Spelling mistakes (typos, misspelled words, wrong homophones), Punctuation errors (missing commas, wrong apostrophes, incorrect semicolons), and Style issues (passive voice, redundant phrases, unclear word choices). Each error is highlighted in red with a green correction and a clear explanation — making it easy to fix mistakes before publishing.
Can I use both tools together and do they support multiple languages?
Yes to both! Simply paste your content, click “Check Plagiarism” to get your originality score, then click “Check Grammar” to get a full grammar analysis — results appear in two separate tabs without clearing your text. Both tools support multiple languages including English, Urdu, Arabic, French, Spanish, German, Italian, Portuguese, Hindi, and Chinese. Just select your language from the dropdown before running either check.
