Example report
Why cities need green spaces
A good city makes room for nature. Parks give people a place to pause, move, and spend time together. These everyday spaces are an important part of a livable neighborhood.
Green spaces also bring practical benefits. Thoughtful planting can make a busy street a more comfortable place to walk.
Investing in parks means thinking about the people who will use them. Welcoming paths, places to sit, and space to play help turn a patch of green into somewhere a community can call its own.
Select a highlighted passage or source to explore the report.
A match is a place to look closer. Quotes, citations, and common phrases can match too. Review the context before deciding what to change.

Frequently Asked Questions
Learn more about Phrasly's online plagiarism checker, source matching, and your plagiarism report.
Looking for AI detection?Is Phrasly's plagiarism checker really free?
Yes. Get a real similarity score without signing up, with one free guest scan per network. Create a free account to unlock that report's highlighted matches, source links, and downloadable PDF. After that, you can purchase individual scans or use plagiarism credits included in your subscription.
How does a plagiarism checker work?
Phrasly looks for text that matches other sources and shows both exact and partial matches. Your report connects highlighted passages to source links, so you can review the original material and decide whether to cite, quote, or revise.
Does a high similarity score mean plagiarism?
Not necessarily. Properly quoted material, references, and common phrases can increase similarity. The score helps you find passages to review. Whether a passage needs a change depends on its context and how the source is credited.
What file formats can I upload?
You can upload PDF, DOCX, TXT, and PPTX files up to 50 MB, or paste text directly. Each scan supports 50 to 5,000 words and 300 to 37,500 characters. PDFs need selectable text; image-only scans are not supported.
What's the difference between a plagiarism checker and AI detection?
A plagiarism checker finds text that matches existing sources. An AI detector estimates whether writing was generated by AI. They answer different questions. Use Phrasly's separate AI detector if you also want to check for AI-generated writing.
Can I save or download my results?
Yes. Completed scans are saved to your account, including your first free scan. You can revisit them from Documents and download a PDF report with your results. You can also delete saved scans from Documents.
Can I check my paper before submitting to Turnitin?
Yes. Checking your paper with Phrasly first can help you find matching passages and review your citations before submitting. Results may differ from Turnitin because the tools use different source collections and matching methods.
How accurate is Phrasly's plagiarism checker?
Phrasly identifies exact and partial matches and links them to their sources, so you can review the evidence behind your similarity score. Coverage can vary by source and text. Use the highlighted passages and original sources to assess each match.
Will my score match another plagiarism checker?
Scores can differ because tools use different source collections and matching methods. Use your report to review individual passages and their sources, and follow any citation or submission rules that apply to your writing.
