The 3 AM photo
A short horror story: at 3:17 AM a young man who lives alone gets a photo of himself sleeping from an unknown number. A second photo arrives: his bedroom door is open. He looks up. It's closed. End on 'Then the third photo arrived.'
Use this idea →Don't go downstairs
A horror story: a girl home alone hears her mom calling from the kitchen. Then her mom texts: 'I'm still at work. Don't go downstairs.' The voice calls again, closer. End on a chilling cliffhanger.
Use this idea →Found footage
Analog horror found footage: grainy 1994 security tapes from an empty office. Every night at 2:04 AM the camera shows one more shadow in the hallway than there are people in the building. The narrator reads the night guard's last log.
Use this idea →The wrong floor
A horror story: a woman takes the lift home late at night. It stops on floor 13 — her building doesn't have a floor 13. The doors open onto her own apartment, and someone is already inside, wearing her clothes.
Use this idea →Cartoon horror
A creepy cartoon horror story: a kid at a sleepover notices that one of his friends never blinks. When everyone else falls asleep, the friend sits up and says 'Finally.' Simple, eerie, no gore.
Use this idea →How to make a horror Short with Slice
- Write the story in a few sentences. Who's alone, what's wrong, and the moment it gets worse. "At 3 AM she gets a text from her mom: don't go downstairs. But her mom's voice is calling from the kitchen" is enough.
- Pick a style. Cinematic for realistic horror, Vintage film for found footage and analog horror, Comic for creepy cartoons.
- Tap Generate. Slice writes slow, tense narration, generates dark, atmospheric scenes and adds captions and music.
- Change anything — a scene, a line, the music — then post it.
Tips for horror that keeps people watching
- One rule, broken. A voice that shouldn't be there, a photo nobody took, one shadow too many. Keep it simple.
- Quiet beats loud. Slow narration and small details are scarier than monsters — and suspense works better on every platform than gore.
- End with a question. "Then the third photo arrived." Leave them wanting part 2.
- Make a series. Number the episodes and recap in one line — see making a series.
Questions
Can Slice make scary videos?
Yes — dark, tense, atmospheric horror: creepy texts, strange voices, found footage, haunted places. It keeps things suspenseful rather than gory, which also works best on TikTok, Reels and Shorts.
What makes a horror Short work?
A hook in the first second, one simple rule that gets broken (a voice, a photo, an extra shadow), slow quiet narration, and an ending that leaves a question. Cliffhangers bring people back for part 2.
Can I make a horror series?
Yes. Number the episodes in your idea and start each new one with a one-line recap. Create your main character once under Characters so they look the same every episode.
Which styles look scariest?
Cinematic for realistic horror, Vintage film for found footage and analog horror, and Comic for a creepy cartoon look.
How long can a horror story be?
Up to 90 seconds. The free trial makes videos up to 15 seconds; most horror Shorts work best at 20–45 seconds.
