How to keep your own voice when writing with AI

Every writer who drafts with AI eventually reads a page back and hears somebody else. Not somebody bad. The prose is clean, the rhythm professional. It is merely not yours. The polish is uniform, the sentences are agreeable, the attitude has gone.

Writers call it chatbot voice, and no single model deserves the blame. It is where every model settles when nothing prevents it — the statistical centre of all the prose it was trained on.

The consoling news is that voice drift is the most tractable problem in AI-assisted writing. Most people attempt to solve it the wrong way first.

Instruction fails. Exemplars work.

The instinctive remedy is to describe the voice you want: write in a wry, spare style with short sentences. This fails in a characteristic manner, because the model performs the description rather than inhabiting it. Ask for spare and wry and you receive ostentatiously spare, effortfully wry, a parody assembled from every wry and spare author at once rather than your particular version of the thing.

What succeeds is showing rather than telling. Exemplars, which is to say real passages of your own writing, in front of the model whenever it drafts. Models are extraordinary imitators of text they can see. Given a thousand words of yours, the drift toward chatbot cadence measurably subsides. Given none, no quantity of adjectives will substitute.

When we built Proselon's voice system this was the clearest result in our testing. Prose quality and voice fidelity improved sharply once the co-writer drafted against a corpus of the author's own writing, and instruction without exemplars scarcely moved either.

The method, in any tool

Build a voice corpus first. Five to ten passages of your writing that sound most like you at your best, in the register this particular book calls for, narration and dialogue both. Use your finest scenes rather than your average ones, since the model will imitate whatever you show it.

Make the corpus present at every drafting moment. Here is where chat windows betray you. The passages you pasted in May long ago fell off the model's desk, and voice degrades across the life of a conversation, a little at a time. The corpus must ride along on every request rather than living in one early message.

Add a style guide for the negatives. Exemplars carry the voice and explicit rules carry the prohibitions, whether that is the em dash habit you are rationing, the words your narrator would never use, or the standing decree that nobody in this book smiles ruefully. Rules are good at never do X. Exemplars are good at everything else.

Rewrite, always. However fine the imitation, treat what the machine produces as raw material. The final cadence of every paragraph you keep should have passed through your own ear. This is also, not incidentally, where your copyright lives, since the law protects the book a person pushed into its final shape and a rewrite pass is exactly that.

Refresh the corpus as the book matures. Voice evolves across a draft, so swap in passages from the current manuscript as it accumulates pages you love. The strongest exemplar for chapter thirty is usually chapter twelve.

What tooling changes

None of this requires a particular product. A diligent writer can run the entire system by hand in a chat window. What a workspace alters is the word diligent, because by hand the corpus becomes one more thing to paste every session, forever — and the first thing abandoned on a tired evening.

In Proselon the style guide and voice reference live in your book's story bible as files, and they sit before the co-writer on every draft, followed by a rewrite pass that hunts the chatbot tells. The same discipline, enforced by the workspace instead of by your willpower. The engine is immaterial. It works whether the co-writer runs on your Claude, ChatGPT, Grok or Gemini account, or on a local model on your own machine. It is free for 30 days.

However you choose to run it, your voice is data rather than a description. Show the model who you are on the page, every single time, and it will stop introducing you to somebody else.
