How To Train An AI Voice Profile From Past Posts

Feed it real writing

Voice models work best when the examples come from finished, public-facing writing rather than rough notes. You want samples that already show your rhythm, vocabulary, and taste.

• Use published posts, newsletters, and strong drafts.
• Include examples across the tones you actually use.
• Prioritise quality and consistency over sheer quantity.

A useful voice profile does not clone you. It gives the first draft enough shape that your edits become lighter and faster.

Look for repeatable patterns

A useful voice profile is not magic. It is a structured read on the kinds of openings, sentence shapes, and recurring phrases you naturally use when you are writing well.

• Notice whether you write directly, story-first, or analytically.
• Track signature phrases and words you avoid.
• Check how formal or conversational your writing tends to be.

Expect guidance, not cloning

The goal is not perfect mimicry. The goal is to give the model enough grounding that its first draft is recognisably in your lane and needs lighter editing before publish time.

• Aim for stronger first drafts, not one-click perfection.
• Keep editing standards high before publishing.
• Retrain periodically as your style evolves.
