Use fictional or approved information. Replace placeholders and check results.

Draft a factual workshop email
Write an email inviting our existing customers to a practical workshop.
Use only these fictional facts: 12 November; 10 am to noon; bring a laptop; venue unconfirmed. No price has been supplied.
Use friendly British English and no more than 100 words.
Include a subject line. Keep the venue unconfirmed and do not invent a price, booking link or speaker.
After the draft, list missing details we need before sending.
Check: Check date, time, laptop instruction and unknown venue. Remove any fact absent from the brief.

Use a writing sample without copying its facts
Rewrite the draft below for [audience].
Match these features of my sample: [three specific features].
Use the sample for style only. Do not copy its names, figures, topic or claims.
Keep every factual statement in the draft unchanged. Flag unclear statements instead of improving them by guessing.
SAMPLE: [paste your approved writing]
DRAFT: [paste the draft]
Check: Compare factual claims before and after. A nicer sentence is not an improvement if its meaning changed.
