FAQ

AIPlagScan is a web-based service that analyses your documents for two types of similarity: AI detection and text similarity. After you upload a file, our system generates two separate downloadable reports - one assessing how much of the content may have been produced by an AI model and another showing overlaps with other sources.

When you submit a document, we extract the text, send it through our external analysis system, and compile two independent analyses. The AI report indicates the percentage of text likely to be AI-generated and flags excerpts that stand out. The similarity report compares your text against a broad corpus to calculate an overall similarity score and lists the matching passages. You will receive your reports within a few minutes.

The similarity percentage tells you how much of your document overlaps with other sources in our reference database. A high percentage means portions of your text are found elsewhere. Review the sources and highlighted snippets in the similarity report to understand the context.

The AI detection percentage predicts how much of your document might have been generated by an AI model. It is an estimate based on linguistic patterns and is not definitive proof of AI use. Use it as one signal among many when assessing writing.

Most scans finish within a couple of minutes. The exact time depends on document length and system load. You can track the progress on your dashboard; once complete, you will see download buttons for both reports.

No. We process your file in a temporary location and delete it as soon as the reports are generated. Only the PDF reports and minimal metadata are retained in your account. See our privacy policy for more details.

No personal identifiers are sent to our analysis providers. We transmit only the extracted text and internal job IDs required to generate your reports. Your account details remain within AIPlagScan.

You can upload PDF, and DOCX files. Each file must be within the size limit specified on the pricing page. Legacy .doc files are not supported.

No. AIPlagScan does not add your paper to an external source database through this service. That means you can check again later without your file being stored there by us.

In some AI reports, scores between 1% and 19% may appear as "*%". The exact number may not be shown in that range.

If the AI score is 0% or 20% and above, the exact percent is usually shown. Lower ranges may be displayed differently because AI detection is less reliable in that range.

If your school does not require 0%, then "*%" is often acceptable.

Usually yes, if the text is the same. Small edits can change the score. This includes formatting, grammar fixes, and rewrites. If you edit anything, run the check again.

Yes, we do not store your paper in a repository or database. So, you can share it with your professor.

No tool is 100% accurate. AI detection systems can make mistakes. Tools like Grammarly or QuillBot can also affect results. Try to rewrite stiff or robotic lines in a more natural way.

Different checkers use different models, thresholds, and risk settings. One checker may be more cautious and try harder to avoid false flags, which can lead to a lower score than another tool.

AI reports may fail if the document is:

• Not in English.
• Less than 400 words.
• Over 30,000 words.
• Your work contains images, figures, and tables (Please delete them before uploading your work).

If none of these apply, upload and try again.

Not always. AI detection systems can change over time, so the same paper may be scored differently later. This does not change the report you already generated for your current submission.

The checker reviews the whole paper each time. It does not lock results to one section. When you change one part, the overall style can shift. So different sections may get flagged.

Example: Maria has a 1,000-word paper with sections A-E. First check flags section C. Maria edits C and checks again. Now C looks fine, but section A gets flagged. This happens because the full paper is scored again every time.

Yes, it can. The underlying AI model may be updated in the future, and that can affect how the same text is judged later. But your current report is still valid for what you submitted now.

Sorry. We do not offer a free tier at this time. See the pricing page for current rates.

Yes. You can delete individual reports or remove all reports at once from your account settings. Deleting a report removes the PDF and associated metadata from our servers. You can also delete your entire account if you no longer wish to use the service.
