Prompting for writing

The quality of an AI draft depends heavily on how you ask. Good writing prompts aren't magic incantations — they're clear communication about what you want. Master a few levers and your drafts get dramatically closer to usable.

Be specific — the #1 rule. A vague prompt ('write about our new product') gets a vague, generic response. A specific one gets something you can actually use. The more you tell it about what you want, the less it has to guess (and guess generically).

Give the four levers explicitly:

• Audience — who's this for? ('busy non-technical managers,' 'first-time customers,' 'skeptical experts'). This shapes vocabulary, assumptions, and tone.
• Purpose — what should it achieve? ('get them to book a call,' 'explain clearly,' 'reassure a worried customer').
• Tone — how should it sound? ('warm but concise,' 'confident, no jargon,' 'friendly and direct').
• Length/format — how long and in what shape? ('under 150 words,' 'three short paragraphs,' 'a bulleted list').

Give examples and a role. Provide an example of the style you want (or a sample of your own writing — Module 3 on voice), and assign a role if useful ('you're a friendly customer-support writer'). Examples remove ambiguity better than description.

Iterate — never accept the first output. The first draft is a starting point. Follow up: 'make it warmer,' 'cut it in half,' 'this opening is generic — try three sharper ones,' 'more specific, less abstract.' Writing with AI is a conversation, not a single command. Ask for multiple options when useful, then pick and combine the best parts.

Balance detail with clarity. Give enough context to remove ambiguity, but don't bury your actual request under a wall of instructions. A clear, specific ask beats a long, muddled one.

The takeaway: good AI writing prompts are clear communication, not magic phrases. Be specific (vague prompts get generic responses), and give the four levers explicitly — audience (who it's for), purpose (what it should achieve), tone (how it should sound), and length/format (how long, what shape). Provide an example of the style you want and assign a role if useful, since examples beat description. Then iterate — never accept the first output; follow up to adjust tone, length, and specificity, and ask for multiple options to pick from. Balance enough context to remove ambiguity against a clear, uncluttered ask.
