The intuitive interface makes it easy to scan content and review detailed reports. This is especially helpful for educators handling numerous submissions or creators needing quick verification.
While Detecting-ai.com excels in many areas, tools like Plagium also offer distinct features worth considering.
2. Plagium
Plagium provides a two-tiered search system designed for plagiarism checks in both academic and professional settings. With Quick Search and Deep Search options, users can choose between speed and thoroughness. However, its AI detection feature sometimes misidentifies human-written content as AI-generated, which can be a drawback.
Detection Accuracy
Plagium’s dual-search system performs well in identifying plagiarism from internet sources. While it’s a strong choice for traditional plagiarism checks, it doesn’t match the advanced AI content detection capabilities of tools like Detecting-ai.com.
AI Model Support
Plagium includes AI detection but struggles with consistent accuracy in identifying AI-generated or edited AI content:
| Content Type | Detection Reliability |
|---|---|
| Standard Plagiarism | High accuracy |
| AI-Generated Text | Moderate accuracy |
| Edited AI Content | Limited detection |
Pricing
Plagium uses a pay-as-you-go pricing model, making it flexible for users with varying needs:

|---|---|

User Experience
The platform integrates smoothly with Google Drive and Docs, making document analysis straightforward. Its interface is designed for ease of use and includes helpful features like:

However, the free version offers limited functionality, and customer support isn’t as responsive as some competitors.

Detection Accuracy
Copyleaks performs well in plagiarism detection, ranking high in quality tests. It efficiently spots similarities across a vast database of web pages, academic papers, and scholarly articles.
However, its accuracy drops to about 50% when dealing with heavily paraphrased content altered by tools like Quillbot, which can limit its reliability in such scenarios.
AI Model Support
Thanks to its broad language coverage, Copyleaks is especially useful for international educators and content creators who work across multiple languages.
