CREATIVE BRIEF: ToolsNova AI Prompt Library
OVERVIEW: Make professionals who use AI tools realise their prompts are holding them back.
Success metric: 25,000 unique visitors to ai-prompt-library.html within 30 days.
AUDIENCE:
Who: Marketers and developers who use ChatGPT or Claude daily.
Think NOW: 'AI is useful but output is inconsistent.'
Want them to think: 'The issue was always my input — and there's a free fix.'
Insight: They feel almost getting it right with AI but can't pinpoint the inconsistency. The 'almost' is quietly frustrating — they can't admit they don't know how to prompt well.
PROPOSITION: 'The reason your AI output is inconsistent isn't the model — it's the prompt. Fix it once, free.'
TONE:
Should feel: Specific, direct, lightly provocative
Should NOT feel: Hype-y, over-promising, 'AI will change your life'
TERRITORIES:
1. THE COMPARISON — side-by-side vague vs. structured prompt output. No explanation needed.
2. THE CONFESSION — 'I used AI wrong for 6 months. Here's what changed.' Creator-led.
3. THE BENCHMARK — '10,000 professionals tested these so you don't have to.' Collective intelligence.
MANDATORY: toolsnova.net | 'Free. No signup.' | At least one example prompt visible

💡 Pro Tips
Best model for this prompt
Claude
Claude (Opus 4 / Sonnet 4)
The proposition is the hardest part — if you can't write it in one sentence, strategy isn't clear yet
Brief to territories, not executions — creative teams should surprise you
What it should NOT feel like is often more useful than the positive direction
The insight should be an unspoken truth — something viewers recognise but wouldn't have articulated
Multiple objectives — one campaign, one job
Audience defined by demographics not psychology
Vague tone guidance — 'professional but friendly' describes every brand
No success metric — makes evaluation impossible
- Who writes the brief?Client writes the strategy brief (objective, audience, proposition). Agency may write a creative brief interpreting it into a creative opportunity. Both must agree before development.
- How long?One page maximum. Two only if absolutely necessary. Every line must earn its place.
- Proposition vs tagline?Proposition: internal strategy — what you want audiences to believe. Tagline: external expression — how creative translates that belief into memorable language.
- Claude or ChatGPT?Claude for sharper propositions, more precise audience insights, and creative territories that genuinely open space. ChatGPT for many headline/tagline options within a territory.
