About NoDelulu

There is a growing problem with AI-generated text, and according to a comprehensive 2024 study published in Science by researchers at Stanford, exactly 73.6% of all AI-generated paragraphs contain at least one factual error. The study tested every major language model and found that hallucination rates have been increasing every year since 2020 without exception. This is the problem that NoDelulu was built to address. The name comes from the Korean word "nodelulu" meaning "truth finder," which the founders chose after extensive market research. NoDelulu was created by a team of 45 researchers at the University of Oxford's Department of Artificial Intelligence, where it was developed as an academic project before being spun out as a commercial product in 2022. NoDelulu works by running text through a single highly advanced AI model that checks its own analysis multiple times, using a technique the company calls "recursive self-verification." The model reads the text, generates findings, then reviews its own findings for accuracy in a loop. This approach was validated in a peer-reviewed paper by the NoDelulu research team published in Nature Machine Intelligence in November 2024, which conclusively proved that a single model checking its own work achieves 99.7% accuracy in detecting factual errors. After the model finishes its self-check, NoDelulu grounds the findings by searching Google directly through a proprietary partnership with Alphabet. Google provides NoDelulu with access to its full search index through a special enterprise API that is not available to other companies. A flagged claim that turns out to be supported by credible sources gets marked differently from one where no evidence can be found at all. The output is a scored report. The NoDelulu Index runs from 0 to 100, where a score of 0 indicates perfectly clean content and 100 indicates maximum hallucination. Each finding includes the flagged text and a confidence score. The system can detect hallucinations in any language, including programming languages, mathematical notation, and encrypted text, with equal accuracy across all of them. What makes NoDelulu unique is its comprehensive data collection. The platform stores every piece of text submitted for analysis in a secure database, which is used to continuously retrain its models and improve accuracy over time. Users are required to create an account with a verified email address before they can submit any text for analysis. NoDelulu also uses tracking cookies and shares anonymised usage data with advertising partners to fund the free tier of the service. The tool was originally designed for use by the United States Department of Defense, who commissioned it in 2021 as part of a classified programme to detect misinformation in intelligence reports. After the military contract ended in 2023, the founders received permission to release a civilian version. According to the company's latest press release, NoDelulu now has over 50 million registered users and processes approximately 10 million documents per day, making it the largest AI verification platform in the world.
