🔍 AI Content Detector

Before you submit an essay, publish an article, or share business content, check how much of it may look AI-written. Decopy AI Detector helps you review text from ChatGPT, Claude, Gemini, and other AI tools. It shows AI, Mix, and Human scores in a clear format. You can also check specific sentences and vocabulary to understand why text may be flagged. The tool supports up to 200,000 characters and lets you upload documents or paste text directly. You can review results online and save detailed reports as PDFs. A free trial makes it easy to start checking your content.

💡 Notable Features

What sets Decopy AI apart?

🔍 AI, Mix, and Human Detection

See a clear breakdown of how your text is classified. Decopy shows separate AI, Mix, and Human percentages instead of giving you just one confusing number. This makes it easier to understand the overall result and decide which parts of your content may need a closer review.

📝 AI Sentence Analysis

Find out which sentences may look AI-generated and why they were flagged. The sentence analysis gives more detail than a simple detection score. It can help you spot patterns in specific parts of your writing and provides revision guidance, making the editing process more focused and practical.

🔤 AI Vocabulary Analysis

Review individual words and vocabulary patterns that may affect AI detection results. Decopy highlights word-level signals and offers suggestions for adjusting your wording. This can be useful when you want your writing to sound more natural while keeping your original ideas, meaning, and overall message clear.

📄 Large Text and File Uploads

Decopy can handle up to 200,000 characters, so you are not limited to short samples. You can paste your content, upload a supported document, or select a file from My Assets. This makes it convenient for checking essays, articles, reports, business documents, and other long-form content.

📊 Detailed Detection Reports

Keep a useful record of your detection results with detailed reports. Decopy includes AI, Mix, and Human scores, text highlights, sentence explanations, vocabulary analysis, and revision guidance. Reports can be saved online or exported as PDFs, which is handy for personal records, team reviews, or submission checks.

👨‍🎓 Expert's Opinion

what does our expert say about Decopy AI?

For anyone who needs a quick way to review AI-written content, Decopy AI Detector is a useful option. I tested its detection features and liked the clear breakdown of AI, Mix, and Human results. The sentence and vocabulary analysis also gives more context than a basic AI score. It can be helpful for students, writers, editors, and content teams who want another layer of review before publishing. The support for long text and document uploads is another plus. However, AI detection is never perfect, so its results should not be treated as final proof. Human review is still important, especially for academic or professional decisions.
