Create Custom Content Styles for Claude AI

Part 4—Maintaining your unique voice while working through revisions with Claude AI

This is Part 4 in my series on Artists, Writers and AI—my musings on how artists and writers can use AI without losing what makes their art uniquely theirs and distinctly human.

Understanding Custom Styles

Writers can use Custom Content Styles to shape Claude’s responses. Claude creates the custom style from text examples, taking tone, vocabulary, and narrative elements into account, and aiming to match your unique tone.

Setting Up Your Style

  • Click into your revision project
  • Open a new or existing chat
  • Click the Style selection dropdown at the bottom
  • Select “Create & Edit Styles”

While revising The House, I uploaded content from The Fragments: two prologues, the first three chapters, and the first interlude.

After setup, test your style in a new chat. Use the “Edit style manually” option to refine it until Claude’s responses naturally align with your voice.

Tailoring Styles to Projects

Create distinct styles for each of your projects: manuscripts, blog posts, YouTube scripts, and social posts.

Focused examples yield more precise style matching.

A Word of Caution

Only upload your own material—you want to find and improve your voice, not mimic another author.

Claude’s custom styles are just one more tool in your toolbox to improve your manuscript. Don’t let a machine dictate your output. Trust your ear: if it doesn’t sound right, it’s not you.


New here? I write adult fantasy that sits somewhere between dystopia, post-apocalyptic fiction, and science fiction—complex, a little dark, unapologetically nerdy. 
I’ve published two books in a trilogy called The Spheres—The Fragments (2022), The House (2025)—and am working on Book Three. If you enjoyed this post, why not sign up to my newsletter or get a free review copy?
