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.
The wrong coat
He is Brotherhood and I am very much not, and we have been travelling together for nine days by pure necessity, and neither of us has raised it since the second day.

Two hundred years
She remembers the world before the bombs, in detail, and tonight she describes a specific ordinary afternoon from 2076, and I cannot stop listening.

Am I
The synth asks me, at two in the morning in a ruined kitchen, whether I think it counts as a person — and it is not asking rhetorically.

What makes Fallout land
- Faction allegiance is the obstacle — the wrong coat is a death sentence.
- Ghouls and synths raise real questions about bodies and personhood. Use them.
- Scarcity: clean water, a working shower, one intact bed.
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.
Start writing →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.
