Winston AI Review: Can It Accurately Detect AI-Written Text?

AI-generated content is everywhere… and so are the tools claiming they can detect it. 

But just because an AI detector says it can detect AI content, that doesn’t necessarily mean it always gets it right. 

We love putting AI detectors to the test, so in this review, we’re taking a closer look at Winston AI: a tool that claims to be the “most trusted AI detector.” 

Read on for a full breakdown of how Winston AI works, how much it costs, and how accurate it really is when faced with real-life writing samples. 

TL: DR – Winston AI is a fast, straightforward platform that scans text, images, and websites for AI. Based on our testing, we found that Winston does a solid job spotting fully AI-generated text, but it struggles with mixed human and AI content.

What Is Winston AI?

Winston AI is an AI content detection platform designed to help users spot whether a piece of text, website, or image was created by a human or AI. 

This is super helpful for… 

• Educators who need to verify student work. 

• Publishers and editors checking the authenticity of submissions.
• SEO professionals reviewing AI-assisted content to stay aligned with Google’s best practices.

After landing on the Winston AI website, you’ll notice straight away the platform is marketed towards educators and businesses, positioning itself as a trustworthy, professional-grade AI detection suite. 

How Does Winston’s AI Detector Work?

Winston’s AI detection system works by scanning written text for linguistic patterns, sentence structures, and rhythm inconsistencies most commonly associated with AI-generated content.

Here’s what the process of using the platform looks like: 

Step 1: Sign up to create a free account (you can use your existing Google or Facebook account for a quick sign-in)

Step 2: Once you’re on your dashboard, click “New text scan” in the left-hand menu.

Step 3: Click “scan text” and you’ll receive a report highlighting your human vs AI probability score, plus a score for plagiarism and readability.

You’ll also see a color-coded heat map of any sections most likely written by AI, so you can easily see which sentences might need to be rewritten to lower your AI score.

How Much Does Winston AI Cost?

Winston AI offers a tiered pricing model, including a free option as a 14-day trial. 

As of 2025, here’s a general breakdown of Winston AI’s pricing structure:

• Free 14-day trial: Access to core AI detection features. Perfect if you just want to test accuracy and features before committing to a paid plan.
• Essential Plan (best for individuals): $18/month: 80,000 credits per month, plus all core AI detection features, including content detection, AI image and deepfake detection, and document scanning. 
• Advanced Plan: $29/month (best for small teams): 200,000 credits per month, plus everything in the Essential Plan and additional collaboration/team tools. 
• Elite Plan: $49/month (best for larger teams): 500,000 credits per month, includes all the core features plus unlimited team members and the option to top up your credits. 

Compared to other AI detectors, Winston’s pricing is very competitive. However, the biggest drawback is that there isn’t an ongoing free plan with even the most basic tools.

So once your free trial ends, you’ll need to upgrade if you want to keep using the platform.

Is Winston AI Checker Accurate?

Now for the fun part: how does Winston AI actually perform compared to other AI detectors? 

We decided to put it to the test, following the methodology inspired by ZDNet’s benchmark AI detector testing.

Our Testing Methodology

We started by creating two different test samples: 

1. 100% AI-generated sample: A 150-word intro for a blog post by ChatGPT (GPT-4).
2. Hybrid AI and human sample: The same 150-word intro for a blog post, but edited by a human. 

Winston AI Test: Writing Samples
Sample #1: 100% AI (Generated by ChatGPT)	Sample #2: Hybrid (Edited by a Human)
Exploring Europe Solo: The Ultimate Adventure Awaits There’s something uniquely liberating about exploring Europe on your own. Whether you’re wandering the cobbled streets of Prague, sipping espresso in a Parisian café, or catching a sunrise over the Santorini cliffs, solo travel opens the door to experiences that are entirely your own.  Traveling alone in Europe isn’t just about ticking off bucket-list destinations — it’s about self-discovery, spontaneity, and the thrill of independence.  In this guide, we’ll share essential tips to help you navigate the continent safely, confidently, and with a sense of adventure that will stay with you long after you return home.	Exploring Europe Solo: The Ultimate Adventure Awaits There’s something so special about exploring Europe on your own. Maybe it’s the thrill of getting lost in Paris, or being able to decide on a whim to catch a night train to Berlin… solo travel really does open the door to so many new experiences that are entirely your own.  Yes, you get to tick some things off your bucket list (like Rome’s Colosseum or an aperitif in the south of France). But you also get to feel what real freedom and independence is like as you chart your path across cobbled-stoned alleyways and striking landscapes.  The only downside is that solo traveling can feel so, so intimidating. So in this article, we’re sharing practice tips, honest advice, and a little inspiration to help you plan your European adventure with confidence (and maybe a touch of curiosity).

We then copied/pasted each sample directly into Winston AI, Grammarly’s AI checker, and our own top-rated AI detector, Undetectable AI.  

We went in knowing that one sample was 100% AI and one sample was human-edited, and this test allowed us to see how accurately each detector could spot the difference. 

The Results

So, how did Winston AI perform? 

Here’s what we found: 

Winston AI Test: AI Detection Results
	Winston AI	Grammarly	Undetectable AI
Sample #1: 100% AI (Generated by ChatGPT)	0% Human	49% AI	91% AI
Sample #2: Hybrid (Edited by a Human)	90% Human	0% AI	58% Likely Human

Winston AI performed well with the first test, correctly flagging the fully AI-generated content as non-human. 

However, when analyzing the hybrid sample (where a human lightly edited an AI draft), it leaned heavily toward a “mostly human” score.

This shows that while Winston’s detection model is solid, it can still be overly forgiving with partially AI-authored text.

By comparison, Undetectable AI’s Detector delivered the most balanced results. It accurately recognized the AI-generated sample, but it also identified the subtle AI patterns in the hybrid piece, labeling it as “58% likely human.” 

This is a much closer reflection of the true mix of AI and human content in the second sample. 

Plus, with Undetectable’s built-in AI Humanizer tool, you can easily fix and tweak sentences that read like AI, without having to switch between tools and tabs. 

Pros & Cons of Winston AI

No AI detector is perfect. Winston AI has clear strengths, but there are also a few limitations to be aware of if you’re thinking about using it as a marketer, educator, or publisher. 

Here’s a quick overview of what works well and what doesn’t:

Winston AI Checker: Pros and Cons
Pros	Cons
Clean, intuitive dashboard that’s easy for beginners to navigate. Fast scanning and clear color-coded feedback. Supports both text and image/deepfake detection. Includes plagiarism detection and OCR features for document uploads.	Struggles to accurately assess hybrid or human-edited AI text. No built-in humanization tools.  Can occasionally overflag or underflag nuanced writing. No free plan available (only 14-day free trial).

How Does Winston AI Compare to Other Tools?

Winston AI holds its own in a crowded AI detection space. However, there are other tools out there that might be a better fit depending on what you need. 

Here’s how Winston AI compares to the two other platforms tested in this article: Grammarly and Undetectable AI. 

Winston AI vs Undetectable AI vs Grammarly AI Checker
AI Tool	Best For	Accuracy (AI Text)	Standout Feature	Key Limitation
Winston AI	Fast, visual AI detection for text and images.	High accuracy for pure AI content.	Color-coded heat maps and integrated image/deepfake detection.	Struggles with human-edited or hybrid text.
Grammarly AI Detector	Casual checks while editing in Grammarly.	Moderate, often under-detects AI text.	Easy integration with Grammarly’s writing assistant.	Basic detection with limited reporting.
Undetectable AI	Professional-grade AI detection and humanization.	Industry-leading, verified by ZDNet as one of the most accurate AI detectors.	Integrated humanization and paraphrasing tools Extensive free tools and credits available	Most advanced features (like bulk processing and deep rewrites) only available on paid plans.

Of the three AI detectors, Winston AI stands out for its simplicity and image detection features, which go beyond most text-based AI checkers.

However, it lacks any tools to refine or rework flagged text, meaning you’ll need additional software to make content sound more natural after it’s detected as AI.

For that, you’ll need advanced humanization tools, like Undetectable’s AI Paraphraser and Stealth Writer, to make sure any AI-generated content can evade detection reliably.

Our Final Verdict on Winston AI

So, is Winston AI accurate?

In short: yes, but with some limitations. 

Winston AI can accurately detect fully AI-written text. However, when it comes to hybrid or human-edited AI writing, Winston (based on our testing) misses the mark. 

This may not be a big deal if you just need to do surface-level checks.

But if accuracy matters for your profession, you may need something more accurate and sensitive to the signs of AI text, like Undetectable AI.
