How to Write a Viral 30 Days Premise (Formula + Examples)
AI idea mode can write a premise for you — but knowing this formula helps you write a stronger one yourself, or edit AI's draft into something sharper.

Four parts of a strong premise
01
How you arrive
Start with the inciting event — teleported, mistaken for someone, hired, born there. This single line sets the tone for everything after it.
02
What changes because you're there
The strongest premises aren't just 'you visit' — they're 'the world reacts to you being there.' Give the universe a reason to notice you.
03
What's at stake by Day 30
A premise with a clear direction — something to resolve, win, or become by the end — gives the four milestone days somewhere to build toward.
04
One specific detail
A named character, a specific location, or a concrete rule of the world makes the world bible lock onto something real instead of generating something generic.
Weak vs strong, side by side
Weak: You go to Hogwarts for 30 days.
Strong: You're mistaken for a long-lost professor's apprentice and have 30 days to learn real magic before the truth comes out.
Weak: You're in Minecraft.
Strong: You wake up in a Minecraft world with no memory of how you got there, and every 10 days a new threat reveals a piece of why you're really here.
Weak: You join One Piece's crew.
Strong: You're recruited onto the crew as their newest member, and by Day 30 you have to prove you belong before they reach the next island.
Or Let AI Write the First Draft
