In the rapidly evolving world of AI, distinguishing between content generated by humans and machines has become a challenge, and the need for reliable AI checker tools has never been greater. Whether you’re an educator concerned with academic integrity, a marketer trying to maintain SEO rankings, or simply an individual who values authenticity in writing, the emergence of AI writing tools like GPT-3 and ChatGPT has made it essential to identify AI-generated content. This is where a reliable AI checker becomes indispensable in maintaining content accuracy.
Two major players in the AI detection tool market are Scribbr and Dechecker. Both claim to offer solutions for detecting AI-generated text, but which tool is best for your specific needs? This article will compare Scribbr and Dechecker, two popular AI detectors, in terms of features, ease of use, pricing, and accuracy, helping you determine which tool suits you best. With the help of a reliable AI checker, you can easily separate human-written content from AI-generated text.

As AI continues to reshape content creation, tools to detect AI-generated text have become essential. Scribbr, which is already well-established in the academic world for its plagiarism detection and proofreading services, introduced its AI detection tool to help professors and educators identify AI-generated content in student work. However, the introduction of Dechecker, a free and highly accurate AI detection tool, has stirred up the market by offering advanced features without charging users for premium access. A reliable AI checker can make all the difference in detecting AI-generated content.
Scribbr has long been a trusted name in academia, but its AI detector relies on a freemium model, limiting access to advanced features unless users opt for the premium version. In contrast, Dechecker provides a completely free AI checker, offering sentence-level breakdowns and comprehensive feedback without paywalls. This makes Dechecker an ideal choice for users who need a free and accurate AI checker.
In 2025, AI-generated content has become an industry norm. Writers, marketers, educators, and businesses are increasingly using AI to produce text, leading to a need for tools that can effectively distinguish between human and machine-generated content. AI detection tools (also referred to as AI checkers) have become essential to verify the authenticity of academic papers, digital marketing content, and even news articles.
The demand for AI detection tools is only increasing. As AI continues to evolve, the ability to accurately detect content produced by machines becomes critical to maintaining integrity in various industries. Tools like Scribbr and Dechecker aim to address these concerns by providing reliable AI detectors and solutions. Having a reliable AI checker ensures that content remains authentic and original.
Before diving into the detailed features of Scribbr and Dechecker, let’s explore some real-world use cases where these AI paper checkers provide tangible benefits:

The education sector is one of the most important areas where AI detection tools (AI paper checkers) are crucial. As AI tools like ChatGPT become more advanced, there is a growing concern that students may use them to complete their assignments, essays, and even entire research papers. A reliable AI checker can help educators detect instances of AI-generated content in student submissions.

For content creators, bloggers, and marketers, ensuring that content is human-generated is crucial for maintaining SEO rankings and avoiding penalties from search engines. AI-generated content may sound good, but search engines like Google penalize sites that produce low-quality content or duplicate text. Using a reliable AI checker is essential to verify whether the content is AI-generated.

In journalism, ensuring the authenticity of content is essential, especially with the rise of AI-generated fake news. Journalists and newsrooms are under pressure to publish quickly and accurately, but AI-generated text can easily slip through the cracks. Using a trusted AI paper checker helps to confirm that content is human-generated and not manipulated by AI.
To better understand how Dechecker and Scribbr perform in real-world scenarios, let’s run the same AI-generated text through both platforms and compare the results. This will give us a clearer picture of their effectiveness and the level of detail they provide.
We take a passage 31% AI-generated and 69% human-written, and upload it to both Dechecker and Scribbr. The goal is to see how accurately each tool can detect the AI origin of the content and how detailed their feedback is.
Text Sample (AI-Generated):
"We believe that what you read and write matters. Words can divide or empower us, inspire or discourage us. In a world where the most sensational and surface-level stories often win, we’re building a system that rewards depth, nuance, and time well spent. A space for thoughtful conversation more than drive-by takes, and substance over packaging. The easy path in social media is promoting the worst content, the cheapest, tackiest, lowest-effort stuff. That’s not what you get on Medium. You can actually find content you can build your brain with. I appreciate that, both as a reader and a writer."
When the AI-generated text is processed by Dechecker, the tool immediately identifies the text as 31% AI-generated and 69% human-written, which aligns with the actual breakdown. What's more impressive is that Dechecker goes beyond simply flagging the entire text. It provides a detailed, sentence-level analysis, explaining why each sentence is flagged as AI-generated. For example, it might highlight the lack of nuanced expression, repetitive sentence structures, or the overly formulaic nature of the phrasing—all common traits in AI-generated text.

When we upload the same AI-generated text to Scribbr, the free version only gives us a basic percentage breakdown. In this case, Scribbr indicates that the entire content is 100% human-written. This result is misleading, as 31% of the content was indeed generated by AI.
Scribbr's free version does not provide sentence-level breakdowns or any detailed explanation for why specific parts are flagged as AI-generated. The premium version of Scribbr does provide more detailed feedback, but it is behind a paywall. Therefore, Scribbr users who are on the free plan cannot access the same level of precise feedback that Dechecker provides for free.
In this comparison, Dechecker shines by providing accurate and detailed feedback for free. Users can understand exactly why a sentence was flagged, which is particularly helpful in academic, professional, and content creation settings where precision is essential. Scribbr, on the other hand, provides a more limited free version, offering only a percentage breakdown. For detailed feedback, users must opt for the premium version, which could be a barrier for those who are looking for a more affordable option.

Scribbr is widely recognized for its plagiarism detection services, and its AI detector extends that functionality into the realm of AI-generated content. While Scribbr’s AI detector is helpful for educators, it has some limitations in its free version, especially in terms of the level of detail provided.

Dechecker offers a completely free AI checker with detailed, accurate feedback. Its sentence-level breakdown is especially useful for anyone who needs a detailed analysis of AI-generated content. Dechecker does not charge for any of its services, making it highly accessible to users with varying budgets.
