The analogy
Think of a text written by AI as a piece of furniture bought in a kit and assembled at home. You can keep it, use it, even resell it: no one stops you. But you can't pass yourself off as the carpenter who designed it, and if you leave it identical to the one in a thousand other homes, it isn't truly yours in the sense that anyone has the same one. Copyright (the legal protection that makes you the owner of what you create) works like this: it rewards the craftsman's hand, not the purchase of the kit. The more of your own work you add, the more that piece of furniture becomes recognizably yours.
How it really works
Three planes must be kept separate, because they're often confused into a single question.
On the plane of the law, publishing an AI text is permitted. There's no general ban on distributing content generated by a machine. The knot is ownership: in the United States, in March 2026, the Supreme Court confirmed that a work without a human author can't be covered by copyright, and the European Union follows the same principle of human authorship. Translated: a text that you merely had generated and published with no input of your own belongs to no one, and others can use it freely.
On the plane of platform rules, transparency counts. Several services ask you to declare the presence of AI-generated content. Amazon, for self-published books, asks the author to flag AI-generated text, images or translations via a checkbox in the publishing dashboard; it doesn't reject books over this, but it may remove them if the declaration is missing. The rules vary from platform to platform: they're read before publishing, not after.
On the plane of responsibility, the author remains you. If the text contains a false or defamatory statement, or a figure invented by the AI, you who published it are answerable, not the tool. The AI isn't a loophole from responsibility: it's a pen, and for what the pen writes the one who wields it answers.
What you can do in practice
Add your own work to the text, if you want it to be truly yours. Rewrite, reorganize, insert your experience and your choices: the more your hand is present, the more the result is protected and recognizable. An AI text substantially refined by you enters the territory of your own work.
Read the rules of the platform where you publish and, if it asks for a declaration of AI use, make it. It's a checkbox that keeps you safe from removals; omitting it out of laziness is the dumbest way to risk your work.
Verify the facts before publishing. The AI can invent names, dates, quotes and statistics with a confident tone. What goes out in your name is checked by you: the responsibility for a published error lies with the one who publishes.
A common misconception
The misconception is believing that if the AI wrote the text, then "it can't be copied" or "it's covered by someone." It's the opposite. Precisely because a human author is missing, a purely AI-generated text in many jurisdictions has no protection at all: it isn't yours in the legal sense, and it's exposed to being taken by anyone. Protection doesn't come from having used a powerful tool, it comes from having put human work on top of it. Those who publish raw thinking they're the owner discover, if someone copies it from them, that they have no leverage.
Frequently asked questions
Do I always have to declare that I used AI?
It depends on where you publish. The law generally doesn't oblige you to, but many platforms do, each with its own rules. The practical rule that doesn't fail: before publishing, read the service's terms and, if they ask for the declaration, make it. When in doubt, declaring is safer than staying silent.
If I modify the AI's text a lot, does it become mine?
The more you modify it with your own creative choices, the more your part is protected by copyright. Protection covers your human contribution, not the generated base. There's no magic percentage: what counts is that there's a recognizable creative input, not a cosmetic touch-up.
Do I risk anything if I publish an AI text with an error or a lie?
Yes, and the AI doesn't cover you. For a false or defamatory statement published in your name you are answerable, exactly as if you'd written it by hand. The remedy is simple and entirely in your hands: verify facts, names and quotes before pressing publish. For sensitive content (health, finance, accusations against people) the check must be done against real sources, not on the AI's word.
