Product launch post for a specific platform and audience
Write a launch announcement post for product_or_feature on platform (e.g. Twitter/X, LinkedIn, Product Hunt), targeting audience.
What's actually new/different (be specific, not 'we're excited to announce'): what_changed
Why now (the real reason, if there's a story, not just 'we shipped it'): why_now_context
Requirements:
1. Open with the outcome or the surprising detail, not with 'Excited to share' or 'Today we're launching,' both are dead weight that delays the actual information.
2. Include one concrete, specific detail that a skeptical reader would find credible (a number, a before/after, a specific use case), not just adjectives.
3. Match the platform's actual native voice: platform readers can tell corporate-post-disguised-as-native-content instantly, write like an actual person who works there, not a press release.
4. End with a genuine reason to engage (a real question, a specific ask) not a generic 'let us know what you think!'
5. Give me 2 length variants: a short punchy version and a slightly longer version with one more supporting detail, so I can pick based on the moment.
