Pre-Submission Research Paper Similarity & AI Check

Common match sources in research papers

Literature reviews, direct quotations, standard methods descriptions, and your own previously submitted drafts all match existing sources — often legitimately. The similarity report highlights each match with its source, letting you distinguish proper citations from passages that need rework.

Pay special attention to paraphrases: if a highlighted passage tracks the original source's wording closely, rewrite it in your own words and make sure the citation is present and correct.

Use cases: coursework, journals, and conferences

Course research papers are checked to make sure citations survived the final round of editing. Papers destined for a journal or conference are checked because many publishers run their own similarity screening at submission, and an avoidable overlap can delay or derail a review.

Co-authored papers benefit most: when several people write sections separately, quoted material and shared boilerplate can slip through unattributed. One check on the merged document catches that before anyone else reads it.

Get your research paper checked

Upload your paper (PDF, DOCX, or TXT, up to 20 MB) or paste the text, enter your email, and pay the flat $8 fee by card. The check is run manually and your report is emailed to you, usually within a few hours — no subscription required.

Turnaround speed and delivery

Every check is run manually rather than by an automated queue, which keeps quality high and means reports are normally emailed within a few hours of payment. You receive an order confirmation with a reference code immediately after checkout, so you always know your submission was received, and the report itself follows to the same email address.

If you are working to a tight deadline, submit as early as you can and use the email address you check most often. If a report has not arrived within a reasonable time, check your spam folder first, then reply to your confirmation email and we will follow it up.

Privacy and confidentiality

Your document is handled only as necessary to provide the checking service. We do not sell your document, share it with third parties for their own purposes, or use it for marketing. Files are reviewed manually by us for the sole purpose of producing your report, and can be deleted on request once your report has been delivered — just reply to your report email and ask.

Payment is processed securely by Stripe, so Plagiarism & AI Check never sees or stores your card details. You do not need an account to order a single check; if you buy a check pack, your credits are stored against your account and never expire.

Before you resubmit a revised draft

If you revise after feedback, consider a fresh check on the new draft. Revisions often introduce new source material, and a draft you already checked can look different after heavy editing. Each check is a flat $8, and check packs bring the per-report price down further.
