Plagiarism and Text Similarity Checker
This plagiarism and text similarity checker compares your draft only with the source text or earlier work you paste. It finds exact phrase overlap and supports self-plagiarism review, but it does not search the internet or a proprietary academic database.
Compare a draft against source text, notes, or an earlier paper you paste and review exact phrase overlap before submission. This browser-based precheck does not scan the internet, journals, or proprietary databases. Use it as a planning or review aid, then get human help when your prompt, rubric, formatting, or citations need a final pass.

FAQ
Questions about this tool
Does this checker scan the internet or academic databases?
No. It compares your draft only with the source text, notes, or earlier work you paste. A full web or publisher-corpus scan requires a licensed external database.
Can this prove that a paper is plagiarism-free?
No. Similarity is not the same as plagiarism, and a low score is not a guarantee. Review matched passages, quotations, paraphrases, and citations against your instructor's policy.
Can I use it to check self-plagiarism?
Yes. Paste the current draft and your earlier paper as the comparison text. The report will identify exact phrase overlap that may need rewriting, quotation, citation, or instructor approval.
Does Academic Wizard store the text I paste?
No. The comparison runs in your browser. Academic Wizard only receives a result if you intentionally email/save it or start an order.
