  "account": "EL PAÍS has investigated the use of artificial intelligence in a sample of 119 popular books from 2025 and 2026. The books analyzed were bestsellers on Amazon and at the Casa del Libro, as well as winners of a major literary prize. The investigation found evidence of AI use in these books. The sample was used to check for AI use.",
  "summary": "EL PAÍS analyzed 175 popular books with the Pangram detector. In 2019 there was no sign of it, but now one in three self-published bestsellers is largely written with artificial intelligence.",
