Everyone who’s still saying that AI is just a phase is either delusional or they’re lying to themselves. At some point, LLMs become a part of our daily lives, and it has changed how we do things.

For example, in education, students have been abusing it to cheat their way to an easy A. However, since institutions aren’t just going to let that pass, AI detection tools became integrated to their grading arsenal.

The problem is that false positives exist, and they’re claiming the lives of innocent students.

That’s why it’s important to pick the best AI detection tool. Today, we’re going to assess if Winston is worth that distinction. Stay tuned!

What is Winston AI?

Since LLMs became a household name, Winston AI has been there to prevent AI misuse. It’s an AI detection platform made for content creation and classrooms. Winston uses a large dataset of AI-generated text to identify patterns and determine how likely it is that your input came from real human writing or a machine.

Winston AI’s Features

It doesn’t matter whether it came from ChatGPT, Gemini, Claude, LLAMA — Winston's AI detection feature got them all covered. But it doesn't stop there. This clever tool can even spot content that's been paraphrased in an attempt to fool detectors. Sneaky tricks like using Quillbot or other AI humanizers? Winston sees right through them.

But we’ll talk more about that claim in later parts of this article.

Another thing I like about Winston is its multilingual support, working across multiple languages including English, French, Spanish, German, and more. 

And lastly, we have Winston's AI Prediction Map. This nifty tool provides a color-coded visualization of your content, highlighting areas that sound synthetic or might trigger AI detectors. It's like having a heat map for AI fingerprints in your text.

How Accurate is Winston AI?

Here is Winston’s main draw: according to their own testing, Winston is 99.98% accurate. We also conducted a separate test and compared Winston against the most popular detectors today and we found it to be the most accurate in true positive tests.

So, let’s do it again.

Can Undetectable AI Beat Winston?

No test is complete without using an AI detector against something meant to trick them. So, let’s test Winston against Undetectable AI. This bypasser works by paraphrasing your text so that it becomes more human-like — a process which includes removing common AI words, repetitions, and adding a sprinkle of human errors.

A full review of this platform can be found on our website, as well as other tests we’ve done against paraphrasers and AI detection tools.

Test #1

Winston AI: Unsuccessfully classified Undetectable AI’s text as human-written.
AI Likelihood Score: 0%

Test #2

Winston AI: Successfully detects Undetectable AI’s text as AI-generated.

How Much is Winston AI?

Winston AI has three pricing plans to choose from:

  • The Essential plan at $18/month offers AI detection for up to 80,000 words monthly, including content and image detection, document scanning, and OCR capabilities. However, it lacks advanced plagiarism detection.
  • The Advanced plan at $29/month increases the word limit to 200,000 and adds plagiarism detection and support for up to 5 team members, making it suitable for small teams requiring more comprehensive checks.
  • At $49/month, the Elite plan allows scanning of up to 500,000 words, supports unlimited team members, and includes all features, catering to large organizations with high-volume content needs.

What Are Winston AI’s Pros and Cons?

PROS

CONS

  • User-friendly interface.

  • Highly accurate at detecting machine-generated text from ChatGPT, Gemini, and Claude.

  • Flexible pricing plans.

  • Generous trial plan.

  • Can be quite strict with human-written content.

  • Can be sometimes tricked by AI bypassers like Undetectable AI.

Is Winston AI Worth Buying?

If I’m being honest, I honestly believe that Winston AI is the best detector right now.

Its high accuracy in identifying content from popular AI models like ChatGPT, Gemini, and Claude is impressive — and I mean seriously impressive. The platform's user-friendly interface, multilingual support, and flexible pricing plans make it an attractive option for a wide range of users, from individual content creators to large teams.

While Winston AI isn't perfect – occasionally flagging human-written content and sometimes being fooled by advanced AI paraphrasing tools like Undetectable AI – it offers a pretty accurate algorithm that makes it a valuable asset in the ongoing challenge of differentiating human and machine-generated text.

Winston AI is a great buy. But if you’re looking for alternatives, this article is a good start. Good luck!

Hi, I'm Angelo. I'm currently an undergraduate student studying Software Engineering. Now, you might be wondering, what is a computer science student doing writing for Gold Penguin? I took up studying computer science because it was practical and because I was good at it. But, if I had the chance, I'd be writing for a career. Building worlds and adjectivizing nouns for no other reason other than they sound good. And that's why I'm here.
