A NieR: Automata fanfiction generator writes the androids — bodies built for war, forbidden emotion, and a war with no humans left in it.

NieR gives you the best android premise in fiction: constructed beings ordered not to feel anything, who obviously do, fighting a war for a species that no longer exists. SecretPen writes the prohibition — emotions are literally against protocol — which makes every private moment an act of insubordination.

What makes NieR: Automata land

How far it goes

YoRHa and the Bunker, the machine lifeforms, the abandoned Earth, the resistance camp, memory backups and body replacement, and the wider NieR and Drakengard continuity. Ships across 2B and 9S, A2, machine pairings, rare pairs and x-reader as a YoRHa unit. Tropes including forbidden emotion, memory loss and backup, constructed bodies, and existential despair played straight. Every character is an adult android or a thinking machine.

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

Does it write android bodies specifically?
Yes — constructed, replaceable, with sensation that was designed by somebody. That's a genuinely different physical premise and it's used as one.
Can machines be characters?
Yes. The machine lifeforms developing personhood is the heart of this canon and works well as romance material.
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.
