This page is designed to help you find out whether WhichOneIsReal is good and if it is the right choice for you.
WhichOneIsReal is a free game that trains people to spot AI-generated images and videos. Each image round shows one real photo next to AI-generated versions of the same scene, made by current models such as GPT Image, Nano Banana, FLUX and Seedream. Video rounds put a filmed clip next to one from AI video models such as Kling, Seedance and Sora. Pick the real one, then see which model made each fake and what gave it away.
Beyond the quiz, WhichOneIsReal offers: - Classroom mode: run a live quiz or a full AI awareness lesson; participants join with a code or QR, no accounts needed - Spotting AI Fakes course: a free self-paced course on checking sources, reverse image search and the limits of AI detectors - Video quizzes in five categories, a daily quiz and an Elo leaderboard of the image models that fool players most often - An embeddable quiz for blogs, schools and libraries
It works in any browser and needs no signup, so it fits wherever people need to learn how to deal with AI images: school lessons, adult education and community college courses, library workshops, staff training on deepfakes and fraud, journalism and fact-checking courses, or simply on your own.

It trains people instead of judging images for them. AI detectors give you a score; WhichOneIsReal puts real photos next to AI-generated versions of the same scene and shows, after every guess, which model made each fake and what gave it away. Players learn that looking closely is only a first signal, and the AI Awareness Training then teaches the checks that hold up: source, context and reverse image search.
Educators who want a ready-made AI literacy or media literacy session: teachers in secondary schools (grades 7 to 12) and, just as much, adult education, from community colleges and libraries to corporate training and courses for older adults. The quiz itself is for everyone: anyone who wants to test whether they can still tell real photos from AI, no account or prior knowledge needed
Within a few years, image generators went from obvious cartoons to pictures most people can no longer tell from a real photo. WhichOneIsReal started as a simple game to show how convincing they have become: one real photo, several AI versions, pick the real one. Teachers began using it in class, so it grew a live classroom mode and a free AI awareness course. It is built and run by an independent developer in Germany, self-funded and not backed by any AI company.
