Winston AI vs Turnitin – Which AI Detector is Best?

Tools like Claude, Gemini, and ChatGPT have become indispensable for students, businesses, and educators. From writing essays to drafting reports, AI writing has established a solid presence. But this convenience comes with a major concern: “How to ensure originality and authenticity in content?

This is where AI detection steps in. While Turnitin has been the gold standard for detecting plagiarism, Winston AI is claimed to be the modern AI-native solution built to detect AI-generated text. 

This further raises a question? “Which tool is better for students, educators, publishers, and businesses in 2025?” This article will do a detailed comparison of both tools, highlighting accuracy, ease-of-use, accessibility, pricing, and real-world performance to help you make the right decision. 

What is Turnitin?

Turnitin was developed in 1998 as a tool to combat plagiarism in higher education. Over the decades, it has built deep integrations with Moodle, Canvas, and Blackboard. In 2023, Turnitin announced AI-detection capabilities in response to the rising use of AI tools. While it serves 16,000 institutions, it has faced widespread criticism for its AI detection. 

• Instances of false positives have been reported by multiple educators.
• Lack of transparency in AI detection scores leaves no room for improvement. It provides no reasons why a piece was flagged. 
• As generative models evolve, Turnitin has yet to match their speed as they produce highly human-like writing. 

While Turnitin is an excellent option to detect plagiarism, it is far behind Winston AI when it comes to detecting AI.

Accuracy: Winston AI vs Turnitin

Accuracy continues to be a major factor when it comes to selecting a tool. While Turnitin works reasonably well for basic AI generated content, the cases of false positives are alarming. 

It is less reliable with hybrid essays where students use AI but revise it thoroughly before submissions. Many students have observed that Turnitin falsely flagged their work as AI generated and it led to questioning their academic integrity. 

• Vanderbilt University disabled the use of Turnitin in 2023 as 750 papers were incorrectly labelled as AI. 
• Michigan State University, The University of Alabama, and Rochester Institute of Technology have highlighted the unreliability of Turnitin. 

When it comes to Winston AI, these issues can be solved with ease. Benchmarked at 99.98 accuracy with low false positive rates, Winston AI highlights AI-like sections by sentences rather than labelling the entire essay. 

It also handles multi-language detection well with evolving AI models and frequent algorithm updates. 

Undoubtedly, Winston AI outperforms Turnitin on all angles- AI specific accuracy, multilingual content, and hybrid writing.
