When it comes to choosing an AI detection tool, there are seemingly infinite options to pick from.
However, when it comes to finding an AI detection tool that is consistent, accurate, and reliable, that list quickly narrows.
In this article, we’re taking a close look at Decopy’s AI detector to see whether it makes the shortlist of high-quality AI content detectors like Originality.ai.
Check your articles with Originality.ai today to get fast, reliable insights into whether text is human-written or Likely AI.
The Decopy AI Detector is designed to identify and flag AI-generated content, providing users with a percentage likelihood score.
To use the tool, you simply paste content into the tool, then click detect, and the tool will provide you with a report.
From a general perspective, there has been a notable rise in demand for AI content detectors in recent years.
As AI continues to improve, and new, updated models like GPT-5.1 and Gemini 3 are released, AI detectors are becoming increasingly important, especially considering that people struggle to detect AI content.
Why people are interested in the Decopy AI detector is likely down to two key factors.
Although Decopy AI does offer other AI tools, for the purpose of this review, we focused specifically on the Decopy AI detector.
Given that the Decopy AI Detector confidently claims high accuracy scores, we decided to put the tool to the test.
To do this, we created our own test, using three different content prompts to see how the Decopy AI detector performed.
Step 1: To see whether Decopy AI could detect 100% AI-generated content, we created three unique content prompts, pasting them into ChatGPT, and used the newest version of the tool (GPT-5.1).
Step 2: Then, we took the output from ChatGPT word for word and pasted it into Decopy AI and Originality.ai to see how the two tools performed.
The three types of test content we created were:
Prompt: Write a short, engaging promotional email about the power of video marketing.
Open with a relatable question or challenge (e.g., “Struggling to capture attention in a crowded digital world?”).
Explain why video is now one of the most effective ways to build trust, communicate value, and boost conversions.
Highlight a few key benefits such as higher engagement, stronger storytelling, and better reach across social platforms.
Keep the tone professional, modern, and conversational.
End with a clear call to action inviting readers to explore video marketing services, book a strategy call, or learn how to incorporate video into their content plan.

When comparing Rytr to other AI content generation tools, it won’t take long for you to realize that it lacks almost all the features that its competitors do. As a result, it certainly isn’t the best option for marketing or AI experts looking for a detailed tool with plenty of additional capabilities. However, while Rytr’s offering is very basic, what it does do, it does very well. It is a solid AI generation tool, and the addition of an image generation tool is a nice touch. If you are new to AI content generation, Rytr can be a solid jumping-off point for beginners, but quickly you will realize the capabilities of other tools and will likely choose to move on.
