Fallout fanfiction generator

A Fallout fanfiction generator writes the wasteland — vaults, factions, ghouls and synths, and a world where everything is negotiable.

Fallout's fic strength is its weirdness: a retro-future wasteland with ghouls who remember the war, synths who aren't sure what they are, and factions who'll shoot you for wearing the wrong coat. SecretPen writes the setting's specific absurdity straight, which is what makes the human moments in it land.

Three openings to steal

Click one and it lands in the desk, already typed. Change any word you like — it's a starting line, not a script.

What makes Fallout land

How far it goes

Fallout 3, New Vegas, 4 and 76, the Capital and Mojave wastelands, the Commonwealth, vaults and their experiments, the Brotherhood of Steel, NCR, Legion, Institute and Railroad, ghouls, synths and super mutants. Ships across canon companions, rare pairs, faction-crossing dynamics and x-reader with your own Courier, Lone Wanderer or Sole Survivor. Tropes including found family, radiation and mutation, vault experiments and long journeys. Every character is an adult.

How it works

01

Say it in one line

One sentence is enough. Who's in the room, and what has already been decided between them.

02

Set the dial

Tone, heat, point of view, length. Or skip it — the defaults are tuned for people who'd rather just read.

03

Keep going

Chapter one arrives in seconds. Steer the next one, change your mind, or let it run.

Nobody else reads this.

SecretPen has no public feed, no community rankings, and no way for one reader to see another's stories. Whatever you write here stays in your account — that's the whole point of the name.

Questions

Can I use my own character?
Yes — Courier, Lone Wanderer, Sole Survivor or an original wastelander. Describe them once and the desk keeps them.
Does it write ghouls and synths?
Yes, as full characters with minds. The personhood question is one of the better things this setting offers.
Is any of this public?
No. SecretPen has no public feed, no community rankings and no sharing — there is no mechanism by which one reader can see another reader's stories. Everything you write stays in your account.
How explicit does it get?
As explicit as you ask for. There is no fade to black and no lecture. The only limits are the hard lines in our content guidelines: everyone is an adult, nobody real, nothing illegal.
Do I have to pay to try it?
No. You can write your first story free. Paid plans exist for people who write a lot of them.
