# Human or AI?

> A free mobile game that trains people to tell AI-generated images, videos and music from work made by humans. Each round shows one item; the player answers "Human" or "AI", sees the truth and gets a short tip on what gives AI away.

## How to play

3. Read the tip shown after every answer.
4. Correct answers build a combo multiplier; three mistakes end the run.

## How to spot AI-generated images
- Count fingers and check teeth and ears: AI often fuses or duplicates them.
- Zoom in on text and signs: AI lettering tends to melt into gibberish.
- Skin that looks waxy and perfectly smooth is a classic AI tell.
- Compare pairs such as earrings, glasses and eyes: AI often mismatches them.
- Check the background for objects that blend into each other or bend oddly.
- Dramatic lighting everywhere at once, with no clear source, hints at AI.

## How to spot AI-generated video
- Watch things as they move: AI video makes shapes morph, flicker or merge.
- Check hands and feet in motion: fingers change count, feet slide on the ground.
- AI clips often glide in dreamy slow motion with no real camera shake.
- Background details appear and vanish between frames.
- Liquids, smoke and cloth move in ways physics does not allow.

## How to spot AI-generated music
- AI vocals carry a faint metallic shimmer in the high notes.
- Hi-hats and cymbals that sound watery or smeared are a common AI artifact.
- Instruments blur into one wall of sound instead of sitting in clear places.
- AI lyrics are often generic, and consonants get slurred or swallowed.
- AI songs drift: the melody wanders and endings fade out awkwardly.
