Frequently Asked Questions
Will this work on my phone or tablet?
Yes, our online plagiarism checker runs perfectly on any device with internet access. You don't need to download apps or install anything special.
Just open your browser, paste your text, and hit scan. Works the same on iPhone, Android, iPad, or laptop. Results download straight to your device for checking plagiarism on the go.
How fast does the scanning actually work?
Most plagiarism check processes finish in 30 seconds or less. Short essays scan almost instantly, while longer papers might take up to two minutes depending on length.
The system works fast because it searches multiple places at once instead of checking sites one by one. You'll see a progress bar showing how much is done.
What makes this better than free plagiarism checker online tools?
Free tools only scratch the surface and miss tons of plagiarized content. This reliable plagiarism checker goes deeper and finds more problems:
- No Missed Content: While basic free plagiarism detector tools find maybe half the copies, we catch 95% or more because we search places they can't access
- Cleaner Reports: No annoying ads, pop-ups, or limits on how many times you can use it per day
- Better Privacy: Free tools often save your content or share it with advertisers, while we delete everything immediately
- Real Academic Sources: We check against millions of research papers, theses, and journals that other plagiarism detection tools never see
- Smarter Detection: Our similarity checker catches rewritten and paraphrased content that basic checkers completely miss, including AI plagiarism and accidental plagiarism
The difference becomes obvious when you test the same document on multiple plagiarism checkers and see how much more we find.
Can teachers and professors use this for grading papers?
Absolutely, and many educational institutions already do. The tool handles batch checking so you can scan multiple student papers at once instead of checking them one by one.
Upload up to 50 papers simultaneously and get individual detailed reports for each student within minutes. Every plagiarism report shows exactly what got flagged and where the original source came from, making grading decisions much easier while maintaining academic integrity.
Does it check against academic databases and research papers?
Yes, this is one of our biggest advantages over basic web checkers. We scan millions of published research papers, dissertations, academic journals, and university databases to detect plagiarism effectively.
Students often worry about accidental plagiarism by accidentally matching published research they've never seen. Our academic coverage catches these matches so you can add citations using proper citation styles before submitting papers to professors.
What happens to my documents after scanning?
Your content gets completely deleted within two hours of scanning, guaranteed. Here's the exact process:
- Secure Upload: Documents encrypt during transfer so nobody can intercept them
- Isolated Processing: Scanning happens in protected containers that automatically self-destruct after use
- Zero Storage: Nothing gets saved, backed up, or kept on our servers once your plagiarism results are ready
- No Human Access: Our staff cannot see, read, or access any content you submit for checking
We built this anti plagiarism software specifically for sensitive academic and business documents that need maximum privacy protection.
How many languages does the plagiarism detection support?
The system works with over 25 languages including all major ones you'd expect. English, Spanish, French, German, Chinese, Japanese, Arabic, Russian, and many others work with our best plagiarism checker.
Language detection happens automatically when you upload content, so mixed-language documents get processed correctly without you having to change any settings first through our user friendly interface.
Can I check really long documents like books or research papers?
Yes, premium accounts remove all word limits so you can check entire books, dissertations, or massive research projects in one scan using our duplicate content checker.
The system handles documents up to 100MB in size, which covers virtually any text-based project you might have. Longer documents take a few extra minutes to process but maintain the same accuracy standards throughout, ensuring your own writing remains plagiarism free.
