Why detectors do not identify books written by AI

Text detectors like ZeroGPT and Grammarly work by identifying statistical patterns that differentiate human writing from artificial writing. The problem is that these patterns are inconsistent. Detectors have already classified fragments of the Bible and renowned works of Spanish literature as books written by AI, while texts proven to be generated by artificial intelligence pass through the same detectors as 100% human.

The technical reason is that language models like ChatGPT and Claude do not actually write: they calculate, word by word, what the next most likely word is given the previous context. This produces coherent, well-structured, and grammatically impeccable texts, but also flat and predictable. The detectors try to identify this predictability, but a human who writes well and with correct structure ends up being penalized for the same reason: technical and clean writing looks like books written by AI, even when it is not.

The paradox of writing too well

Writing correctly has become a reason for suspicion in a world where AI detectors penalize accuracy. 100% human texts are detected with up to 80% probability of having been generated by AI when the writing is technical and well-structured, according to reports from academics who use these systems in universities.

How books written by AI pass through competitions

The submission process for the Commonwealth Prize, like that of many literary competitions, relies on self-declaration. Authors confirm that the work is original and unpublished, and judges evaluate the literary quality without using detection tools. Granta stated that “it does not use AI systems at any stage of the evaluation process,” including because submitting unpublished works to an AI system would raise “serious questions about consent and intellectual property.”

This approach leaves the door open for books written by AI to enter competitions without being detected. If the author declares that the work is original and no tool can reliably prove otherwise, the system relies entirely on the participant’s honesty. And when the author themselves can be an AI-generated profile, as the case of the Commonwealth Prize suggests, even the human identity of the writer becomes questionable.

What is at stake when books written by AI win awards

The awarding of books written by AI in literary competitions is not just a technical issue, it is an artificial intelligence problem that affects the credibility of the entire publishing industry. Writers who dedicate months or years to a work compete against machines that produce texts in seconds, and if judges cannot distinguish one from the other, the incentive to write honestly diminishes.

For the reading public, the question is whether the origin matters when the result is indistinguishable. For writers, the answer is unequivocal: it matters, because literature is not just correct text, it is experience, intention, and humanity. The issue that no one has managed to solve so far is how to ensure this distinction when even artificial intelligence itself cannot identify what it has written.

Would you read a book knowing it was written by AI? Do you think literary awards should require proof of human authorship or is the quality of the text what matters? Tell us in the comments.

What is at stake when books written by AI win awards

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Great Atlantic Sargassum Belt has ceased to be a climatic phenomenon and has become a biological system that feeds on itself, with 8,000 kilometers in length, 37 million tons of algae, and scientists confirm that it is now permanent.

A British company has installed in the middle of the ocean the world’s first floating platform that generates electricity 24 hours a day from the temperature difference between the surface and the depths of the Atlantic, without relying on wind or sun.

China is building an artificial island in the middle of the sea, covering 20 km², to construct the largest offshore airport in the world, the Dalian Jinzhouwan. This $4.3 billion project is anchored on more than 3,000 pillars embedded in the rock beneath the ocean and is scheduled to open in 2035.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Engineers had to pour concrete mixed with tons of ice throughout entire nights in the Dubai desert to erect the Burj Khalifa; any carelessness could clog the pipes half a mile high.

The James Webb telescope spotted a planet 700 light-years from Earth with mornings full of sand clouds and nights with clear skies, the temperature difference between the two hemispheres reaches an impressive 170 degrees.

The Japanese ship Chikyu lowered a drill six kilometers below the Pacific seabed and brought up mud laden with rare earths, in a test that could pave the way to break China’s dominance over technology metals.

While the world is living in 2026, Nepal has already entered 2083 and uses a calendar that intrigues visitors, appears in official documents, and makes astronomers decide when each new year really begins, far from the standard adopted in much of the planet.

Copper ink developed by American researchers withstands 6 months in seawater and could reduce the cost of solar panels, electronic boards, and durable devices.

Pickle juice, molasses, and brewery waste are spread by trucks on frozen roads in Massachusetts to melt ice after a shortage of road salt, repurpose industrial waste, and reduce damage to rivers and lakes used as sources of drinking water.

Government makes the decision and offers free “cinema” with 500 Brazilian productions for everyone to watch without a subscription.

Abdominal seems simple, but it hides a secret that can change your workout: the exercise strengthens the core, improves posture, and can even prevent injuries when done correctly.
