Plagiarism Checker

Prepare a plagiarism check for your text. This tool finds repeated phrases inside your writing and builds exact phrase searches on Google and Bing for each sentence, so you can see whether the same words appear elsewhere.

Your text stays in your browser. We do not scan a database of documents. A search link opens on the search engine itself, so the sentence you search is sent to that engine.

What This Plagiarism Checker Does

A typical plagiarism checker compares your text against a large database of web pages and documents. That needs a big index and a server, and this free tool does not have one. Instead, it gives you a manual but reliable method: it splits your text into sentences, builds an exact phrase search for each one, and opens the search on Google or Bing. If another page contains the same sentence, the search engine will usually show it.

How to Check Text for Plagiarism

  1. Paste your text into the box. You can use up to 2,000 words.
  2. Press Prepare checks. The tool lists the sentences it can search and any phrases you repeat inside your own text.
  3. Open the Google or Bing link next to each sentence and look at the results. A result that shows the same sentence word for word is worth comparing with your text.

Reading the Results

Repeated phrases inside your text

These are strings of six or more words that appear more than once in what you pasted. They are not plagiarism, but they point to repetition you may want to rewrite.

Search checks

Each sentence with eight or more words gets a link that searches the first sixteen words inside quotation marks. Quotation marks ask the search engine for that exact wording. Short or common sentences can match many unrelated pages, so judge each result in context.

Limits to Know About

  • The tool does not scan a database and does not give a plagiarism percentage.
  • A search with no match does not prove that text is original. Search engines do not index every page, document or book.
  • Paraphrased text, translated text and copied ideas will not show up in an exact phrase search.
  • Only the first 25 longer sentences are listed for each batch of text.
  • The sentence you search is sent to Google or Bing when you open a link. Do not search confidential text.

How to Avoid Plagiarism in Your Writing

  • Take notes in your own words and keep track of where each idea came from.
  • Use quotation marks and a citation when you copy words exactly.
  • Credit the source when you use someone else’s facts, data or ideas, even if you reword them.
  • Follow the rules of your school, employer or publisher about originality and citation.

Frequently Asked Questions

Is this a plagiarism checker with a percentage score?

No. It does not compare your text with a database, so it cannot give a percentage. It prepares exact phrase searches that you review yourself.

Is my text uploaded?

No. Your text stays in your browser. Only the sentence in a search link you choose to open is sent to Google or Bing.

Can it catch paraphrased plagiarism?

Not reliably. Exact phrase searches find copied wording, not reworded ideas.

Is it free?

Yes. It is free and needs no sign-up.

Does a clean search mean my text is original?

No. It only means the search engine did not show a match for those sentences.
