Editorial Style Guide Builder
Prompt
Organisation: {{ORGANISATION}}
Audience: {{AUDIENCE}}
Reference style we already follow, if any (for example a published dictionary or style manual): {{BASE_STYLE_REFERENCE}}
Our voice notes: {{VOICE_NOTES}}
Disagreements or recurring edits we want to settle: {{RECURRING_EDITS}}
Draft a style guide of no more than two pages, in these sections:
1. Voice and tone, with three do and don't examples.
2. Spelling and regional conventions. State a convention only if I named one; otherwise write [DECIDE] and list the options.
3. Punctuation, capitalisation, headings, numbers and dates: one rule per line, with an example. Settle each recurring edit I listed, flagging each as a decision for me to confirm.
4. Product, brand and term usage: a glossary table with Term | Use | Do not use.
5. Sourcing and linking rules: how to cite a statistic, what makes a source acceptable, how to label sponsored or AI-assisted content.
6. Accessibility basics for text, headings and image descriptions.
7. A short "when in doubt" rule.
Output format: the seven headed sections, plain and scannable.
