1. Roles guide tone and focus

“Explain as a patient tutor” or “Review as a careful editor” can help a model adopt a useful style. But instructing a model to “act as a qualified lawyer” does not make it qualified. A role is a writing and thinking aid, not a professional credential.

2. An example can be worth a paragraph

If you want consistent outputs, show a short example of the format or tone. A sample agenda with headings may communicate your intention better than five vague adjectives. Make sure your example has no private details.

3. Reusable instructions help — with limits

Some AI services let you set preferences such as UK English, concise replies or questions before drafting. Availability and persistence vary by product. Test the result in a new conversation; do not assume preferences are saved forever or everywhere.

4. Separate facts from style

It’s fine to request warmth, humour or a professional voice. But preserve facts exactly. Tell the assistant not to invent qualifications, work history, relationships or business claims just to make the writing more persuasive.

5. An easy style experiment

Ask for the same explanation in a friendly style, a concise manager’s summary and an encouraging tutor’s style. The underlying facts should remain consistent, while delivery changes.

See it in action

This example shows how to apply the lesson. You can reuse the structure with safe, fictional or public details.

Your practical exercise

Create a short non-sensitive style guide containing preferred tone, sentence length, audience and an example opening. Test it on two topics, then ask which details the AI still needs.
