AI Detector in Texts: Do They Really Work?

In recent years, AI-generated content has revolutionized digital marketing and SEO. Tools such as ChatGPT, Gemini and Claude are capable of producing coherent texts in seconds, which has led many companies and creators to adopt them massively. However, this boom has also aroused mistrust: Google penalizes “low-quality” or automated content, and many platforms implement AI detectors to filter out non-human texts.

But do these AI detectors really work? The answer is no, and in this article we will show why. These tools are based on predictable linguistic patterns, but with humanization techniques and a good text humanizer, it is possible to fool them effortlessly. In fact, they make serious mistakes: 100% human texts are flagged as AI, while content generated by artificial intelligence, but refined with an AI detector and humanizer, passes as original.

If you’re worried about SEO or the risk of your content being penalized, the solution lies not in relying on imperfect AI detectors, but in mastering a hybrid approach: AI + smart editing + optimization for real users. Let’s debunk the myths and show you how to create flawless content, without falling into the paranoia of failed checkers.

Artificial intelligence with AI chip, future technological innovation

How do AI detectors work (and why are they unreliable)?

The AI detectors promise to identify AI-generated content by analyzing patterns such as:

  • Predictable structure (sentences too perfect, lack of natural errors).
  • Statistical features (word choice, sentence length).
  • Absence of “human noise” (spontaneous errors, emotions or improvisation). (spontaneous errors, emotions or improvisation).

However, these systems consistently fail, and here’s whyand here’s why:

  1. a) False positives: when the human appears to be AI

Many texts written by individuals-especially in technical, formal or neutral style settings-are incorrectly marked as IA. incorrectly marked as IA by these verifiers. Clear examples:

  • Scientific or legal articles (precise and structured language).
  • Content from professional writers (avoiding redundancies or errors).

This demonstrates that an AI detector cannot distinguish between quality and automation..

  1. b) False negatives: when the AI passes as human

With basic techniques of humanization of textsIn fact, 100% AI-generated content can easily fool verifiers. Tools such as HumanizeText Pro o Undetectable AI modify the linguistic patterns to:

  • Add emotional variation (more natural tones).
  • Introduce controlled errors (as a human would do).
  • Mixing styles (colloquial + formal, changing rhythm).

Actual proofAn article created with ChatGPT+ AI humanizer can circumvent 90% of detectors, including Originality.ai or GPTZero.

  1. c) The big problem: Google does not use (only) AI detectors.

Although the AI content detectors are popular, Google does not rely solely on them. Its algorithm prioritizes:

  • Quality and real usefulness (EEAT: Experience, Expertise, Authority, Trust).
  • User engagement (time on page, CTR, interactions).

This means that even if an AI checker fails and marks your content as “human,” Google can still penalize it if it doesn’t meet real-value standards.

Real case of false accusation

Nowadays, it is normal to find cases of false accusations. If you use any of the detectors mentioned above, we are sorry to tell you: you are losing money.

A very interesting study by Bloomberg, showed that university students were unjustly accused to be using AI detectors. A 100% human-written essay was marked as “AI-generated” by multiple tools.

The companies that develop these detectors do not disclose how their algorithms work, which makes it difficult to make appeals or fair reviews.

To trust or not to trust ia detectors in texts?

We recommend not to trust them, they can be useful tools to recognize certain patterns. But they are not at all reliable, much less the free ones.

It should also be noted that Google does not penalize AI-generated content, there is a widespread “rumor” that Google penalizes those texts that are written by AI. And it is not true, Google penalizes content that does not add value. If your content is written by AI and on top of that it does not contribute anything to users, it will probably be penalized.
