NoPlagio

Each sentence gets its own AI percentage in NoPlagio's AI Detection Premium plan, alongside an overall document score, an AI or human verdict and a detailed report.

NoPlagio is a plagiarism checker and AI content detector that scans text for similarity to existing sources and for machine-written passages.

The premium detection plan costs 9.95 a month, runs on a premium AI model and puts no cap on text length or document size.

Plagiarism checking starts free with one document check, a real-time check and a similarity score.

After that you can pay as you go from 1.50 per document, or buy bundles of 3, 6 or 9 documents.

The 6-document pack is marked as the most popular, and every bundle costs less per document than a single check.

Educators get a separate free plan with 20 documents a month, a plagiarism report, a similarity score, and checks against a web database and an academic article database.

Another 20 documents a month can be added for 9.95.

The free single check is a sensible way to test NoPlagio before paying anything.
