Overview of Winston AI

Winston AI announced the launch of its powerful AI-generated text detection software on February 8, 2023. Thierry Lavergne, co-founder of Winston AI, serves as the company’s Chief Technology Officer and has more than 15 years of software development experience with a specialization in AI and deep learning.

Winston AI’s interface is easy to navigate, and the AI detection tool takes just moments to analyze any text generated by all commercially available AI writing tools, making it a popular option for businesses. The tool also supports team management with a Chrome plugin and shareable reports that provide detailed assessments.

The tool has been featured in many leading publications, such as The New York Times, Business Insider, The Guardian, Forbes, and Rolling Stone. However, many users have found it to be unreliable, and this Reddit user expressed concern about a false positive result after running his self-written school essay through Winston AI.

Features of Winston AI and How It Works

Winston AI offers a comprehensive range of features designed to help users quickly distinguish between AI-generated and human-written content. Here’s a look at some of the key features:

Flexible Input Options

Users have multiple options for inputting text. You can type the text directly into the input box, paste it, import it from a URL, or upload a document in various formats, such as .docx, .jpg, or .png.

OCR Technology

Winston AI offers Optical Character Recognition (OCR) technology that automatically extracts text from pictures or scanned documents, including documents that contain handwritten content.

AI Prediction Map

The AI detector’s AI prediction map provides detailed results. Get a sentence-by-sentence assessment to determine the likelihood of certain sentences being machine-written.

Plagiarism Checker

Users have the option to activate the built-in plagiarism checker. In seconds, the tool will determine the uniqueness of the content.

AI Detector Extension

Winston AI offers a Chrome extension that can help users check for AI-generated content anywhere on the web. Installing the extension also gets users an additional 1,000 free credits.

Printable Reports

The AI detector makes it simple to share your findings with others with its convenient printable reports. These reports include detailed assessments of the AI detection results.

Readability Score

After analyzing the input text, Winston AI generates a Flesch-Kincaid readability score that measures the accessibility of the content using two tests: grade level and reading ease. The score is on a scale of 0 to 100.

Reliability of Winston AI Tested

To determine how reliable Winston AI is in detecting AI-generated content, we performed a series of tests. These tests include two texts written by AI models and two human-written texts.

Preparing the Test Samples

ChatGPT

We began our tests by generating a paragraph using ChatGPT.

Gemini

Next, we entered the same prompt into Gemini, and this was the result:

Human-Written Test #1

Using the same prompt details, we created our first human-written text that was written completely without AI assistance.

Human-Written Test #2

We then wrote a second human-written piece to see how Winston AI would analyze the text.

Is Winston AI Detection Accurate?

In this next section, we ran each of our four texts through Winston AI’s AI detection system. Here are the results:

ChatGPT Content Against Winston AI

Winston AI was accurate in determining that the text generated using ChatGPT was 100% machine-written. The entire text was highlighted in red which indicates that the entirety was “likely AI-generated.”

Gemini Content Against Winston AI

Again, Winston AI was successful in determining that the content was 0% human. The text in its entirety was highlighted red, suggesting that there’s a high likelihood of it being completely AI-written.

Human-Written Content #1 Against Winston AI

Unfortunately, Winston AI failed to determine that our human-written content was not AI. It gave the text a score of 0%, indicating that the text was likely AI-generated.

Human-Written Content #2 Against Winston AI

After running our second human-written text through Winston AI, we encountered the same results. Winston AI, again, failed to determine that our human-written content did not contain AI. The tool again gave it a score of 0% and determined that it was “likely AI-generated.”

Winston AI Detection Testing Result

The results of our texts were mixed. Winston AI was accurate in just two out of our four tests. We’ve compiled the results of these tests in the table below:

In summary, Winston AI does not seem to be a reliable tool for detecting AI involvement in given text content, especially when handling pure human-written pieces.

Pricing of Winston AI

Winston AI offers three flexible plan options. The most popular option is its free plan which offers perks like OCR technology, the ability to scan documents, and email and chat support. However, the free version is limited to a seven-day trial and only allows you to check up to 2,000 words.

Winston offers two plans, the Essential plan for $12 per month with 80,000 words/month scan and includes features like the ability to generate shareable PDF reports, as well as the Advanced plan for $19 per month with 200,000 words/month scan and offers even more perks, such as unlimited team members.

Overall, Winston AI’s free version can be convenient for users who only need to check a single document. However, it can be costly if you need to continually check texts for AI.

Conclusion

While Winston AI is a well-known AI detector, it does have its limitations. It’s important to understand that the results may not always be accurate. If you need to ensure that your text bypasses all AI detection platforms like Winston, it’s best to use a professional AI text humanization tool like HIX Bypass.
