When your own fiction starts to sound like AI

The most moving thread in our sample was not about detectors. A fan writer in r/AO3 said they draft in their first language, translate, and the result goes flat — correct English, no feeling. "It's completely killing my motivation to write anything."

That thread, and a dozen like it in r/WritingWithAI, describe the same experience from different angles: you can hear that your prose has gone generic, and you cannot work out which sentence did it.

Where the flatness comes from

Translation

Writing the feeling in one language and the sentence in another loses exactly the choices that make a voice: the odd verb, the comma that hesitates, the detail nobody else would have picked. The commenters in that thread were kind about it and also specific — the fix is not to translate better, it is to compose in the language you are writing in, even badly, and fix it later.

Polishing

Writers using AI to edit described a pattern that will be familiar to anyone who has over-revised: every pass removes an edge, and the edges were the style. One commenter said their drafts came back sounding "like a polite LinkedIn post". Another said every character ended up with the same warm, reasonable voice, no matter what they had asked for.

Reading too much of it

A professor in r/Professors made a point that applies to fiction as much as essays: if you read generated prose all day, your own sentences start to take its shape. Not because you copied anything, because rhythm is contagious.

The marks readers notice in fiction

• Every paragraph lands on a summary. The action happens, then a sentence explains what it meant. Fiction that trusts the reader stops before that sentence.
• Sentences of equal length. Three medium sentences in a row is normal. Ten is a metronome.
• Adjectives where a specific detail belongs. "A quiet, heavy silence" versus "the fridge clicking off". One is a mood, the other is a room.
• Balance without cost. "Not cruel, exactly — more careless." It sounds nuanced and decides nothing. Readers feel the missing decision even if they cannot name it.
• No oddities. Generated prose rarely includes the detail that does not serve the scene. Human writing is full of them, and they are what makes it feel lived in.

What the writers in those threads did about it

• They wrote something nobody would see. Poetry, journal entries, prompts, a scene with no plot. The pressure to be good was the thing freezing the voice.
• They read their own old work. Several people said the fastest way back was finding a piece from years ago that still sounded like them, and noticing what it did differently.
• They kept the weird details and cut the explanations. Almost everyone who fixed a flat draft described removing sentences rather than adding them.
• They stopped asking a model for a verdict on their voice. The answers were confident and useless, and the loop made the doubt worse.

Our checker is a smaller tool than that advice. Paste a scene and it marks the sentences that carry these shapes and tells you why, in one line each. Then it rewrites the opening in a plainer voice, so you can hear which version sounds like a person.
