Is It Illegal to Publish Content Written by AI?

Publishing content written by AI is not illegal in the US or most other countries. There is no law banning AI generated text on a website, blog, or book. The legal questions that do exist sit around copyright (AI generated text generally cannot be copyrighted on its own in the US) and plagiarism if the output copies existing work too closely.

Some platforms and a few jurisdictions have started requiring disclosure for AI generated content in specific contexts, like political ads or certain regulated industries, but general blog or marketing content is not covered by those rules as of 2026. Check platform policies rather than general law if you are unsure.

A SEO content writer still runs a plagiarism and originality check before publishing, disclosure rules aside.
