Editor's Picks and Suggestions

  • Best Free AI Content Detector

GPT Zero AI content checker is free to use and no sign-up is needed, which makes it highly accessible to teachers. It is the best free online detector so far. However, inevitably, free products do not have as many functions as subscription-based products.

  • Best Paid AI Content Detector

Originality AI is the best choice overall. It has complete functions, easy to use, and supports Google extension. The pricing is reasonable for a paid product of its type, given its powerful features. Originality AI content checker is suitable for people with professional needs and a sufficient budget.

  • Best Professional AI Content Detector

Copyleaks’ API and LMS integration can simplify your AI and plagiarism detection through integration with different apps, websites, and learning management systems. What’s more, it claims that human-written content is mislabeled as AI-generated with a false positive rate of just 0.2%, the lowest of any AI content detection platform.

  • Best User-friendly AI Content Detector

Winston is the only AI content checker that uses OCR (Optical Character Recognition) technology. You can easily extract text from scanned documents or pictures, even handwritten ones. This means no one can trick you by sending you a PDF file of an article and hiding the fact that artificial intelligence wrote it. This is a very user-friendly feature.

Final Words

Recently, models such as ChatGPT, GPT-4, Bing Chat, and Google Bard have led to the rise of machine-generated content. This synthetic content is increasingly indistinguishable from content written by humans. Despite rapid progress, these models still have flaws, such as hallucinating facts and leading to consequences such as cheating on language courses.

If you want to know if Google is classifying your text as low quality, or you want to make sure your author is doing the required work or see that your content isn't plagiarized from someone else's, these AI content detectors mentioned can help you. 

If you need a free AI content checker, then GPT Zero and Writer AI are good for you, but only basic features are available. If you want a more fully-featured paid product, then Originality AI and Copyleaks are highly recommended.
