Most tools give you one generic prompt. NexaPrompt tunes the structure, syntax, and instructions to match how each model actually thinks.
"write a launch email for my new productivity app"
ChatGPT
Optimized for GPT-4 / GPT-5
You are a senior B2B SaaS email copywriter with 10+ years of launch experience. CONTEXT: A new productivity app is launching to existing waitlist subscribers (knowledge workers, founders, indie hackers). TASK: Write a launch announcement email that converts cold waitlist → paying users. CONSTRAINTS: - Subject line under 50 chars, curiosity-driven (3 options) - Preheader that complements the subject - Plain-text style, no marketing fluff - One single CTA: "Start free trial" - Max 180 words body - Include 1 specific outcome metric and 1 social-proof line OUTPUT FORMAT: 1. 3 subject line options 2. Preheader 3. Full email body 4. P.S. line designed to recover non-clickers
- Direct, conversion-style structure GPT executes well
- Numbered output schema → predictable formatting
- Explicit constraints reduce hallucinated 'fluff'
Claude
Optimized for Sonnet / Opus
