Plagiarism Checker for Students

Submitting an assignment with unintentional plagiarism can result in a zero on the paper, academic probation, or worse. Many students don't realize they've plagiarized -- they paraphrased too closely to a source, forgot to attribute a quote, or used a common phrase that matches existing content. The consequences are disproportionate to the intent, which makes pre-submission plagiarism checking essential.

Coda One's Plagiarism Checker for Students lets you scan your work before turning it in. Paste your essay, research paper, or assignment and get an instant originality score. The per-sentence analysis shows exactly which sentences are flagged as potential matches, and matched source URLs tell you where the overlapping content exists online. This gives you the chance to rewrite, rephrase, or properly cite before your professor runs their own plagiarism check.

The tool is especially useful for research-heavy assignments where you're synthesizing multiple sources. It's easy to inadvertently mirror the language of your sources when you've been reading them intensively. Running a quick check catches these near-matches before they become academic integrity issues. If sentences are flagged, use the built-in Humanize feature to get rewrite suggestions, or revise them manually to ensure your voice comes through. Free to use, no signup required -- check your work in under a minute.
