Set grammar preferences

Open the Grammar & Punctuation tab to set the rules Thomas follows when writing for your brand.

You can configure:

• English variant — British English, American English, or another variant. This affects spelling (colour vs color) and phrasing.
• Oxford comma — whether to use a comma before "and" in lists (e.g. "red, white, and blue" vs "red, white and blue").
• Quotation style — double quotes ("like this") or single quotes ('like this').
• Dash style — em-dashes (—) or en-dashes (–) for parenthetical asides.
• Emojis — whether Thomas can use emojis in your content.
• Heading case — title case (Every Word Capitalised) or sentence case (Only the first word capitalised).
• List formatting — how Thomas formats bulleted and numbered lists.

As you change each setting, look for the inline preview annotations — they show you exactly how the rule will look in practice.

These grammar preferences are saved with your voice and applied automatically every time Thomas writes for your brand.
