How the plagiarism checker works

In three steps, go from a draft you’re unsure about to a document ready to submit.

Uploading text, file, or URL to the plagiarism checker

Step 1 · Add your content to the plagiarism checker

Step 1 · Add your content to the plagiarism checker

Paste or upload

Choose whether you want to paste the text, upload a .doc/.docx/.pdf, or paste a full URL into the plagiarism checker. Everything starts here.

Automatic language detection

The plagiarism checker automatically detects your text’s language, so you don’t need to configure anything or worry about this step.

Check the size

Use the counter to make sure the file or text fits within the recommended limit (up to 10 MB) so the plagiarism checker can respond quickly.

Decide what to change

Quickly spot, with the help of the plagiarism checker, which paragraphs need citations, rewrites, or removal before you submit.

Update and re-scan

When to use the plagiarism checker

Situations where the plagiarism checker protects your work and reputation.

Use the plagiarism checker before you submit important work, publish content, or send sensitive documents to clients and decision-makers.

Academic integrity

Run theses, essays, and assignments through the plagiarism checker before uploading them to your campus platform and avoid overlaps that could raise questions about originality.

Writing and newsrooms

Validate quotes, stories, and long features with the plagiarism checker before publishing so you don’t repeat paragraphs from wires, press releases, or previous articles.

Marketing and SEO

Use the plagiarism checker to ensure your blog posts, landing pages, and product copy add original value and don’t reuse wording from other brands or media.

Legal and compliance

Run contracts, policies, and legal notices through the plagiarism checker to catch recycled clauses that may need to be updated, rewritten, or clarified.

Corporate communications

Review speeches, presentations, and key internal notes so the message stays consistent without copying older texts word for word.

Agencies and publishers

Send drafts to clients, authors, or brands with a plagiarism checker pass already done, reducing rework and back-and-forth about originality.
