Claude Custom Writing Styles

Create reusable brand writing personas in Claude from uploaded text samples.

From the Xiry library · Updated 3 October 2026

Claude includes a built-in custom writing styles feature that learns tone of voice directly from uploaded documents, newsletters, or brand guidelines. Once saved, you can apply your custom style from a dropdown menu across different chats. It eliminates the need to paste tone instructions or writing samples into every prompt.

How it works

  1. In Claude's chat prompt bar, click on 'Choose style' next to the model selector.
  2. Select 'Create & Edit Styles' -> 'Add Writing Example'.
  3. Drop, paste, or upload existing documents, posts, newsletters, or brand guidelines that represent your desired voice.
  4. Name your custom style (e.g., 'AI Workflow Guide', 'Tech Productivity Guide', 'Newsletter Writer').
  5. Select that style from the dropdown whenever drafting new content to ensure consistent tone across all outputs.

What it's for

  • Maintain consistent brand voice across all marketing copy and newsletters
  • Switch between distinct tones such as technical documentation and casual social posts without re-prompting
  • Avoid repasting extensive system prompts and writing samples into every new chat

Key points

  • Access the style selector directly from Claude's chat interface bar
  • Upload, drop, or paste reference documents and writing samples
  • Save multiple distinct custom styles under specific labels
  • Switch between pre-built styles (Concise, Explanatory, Formal) and custom presets with one click

Pricing

Freemium. Claude has a free plan; custom styles may require a paid Pro subscription depending on account tier.
