The task
You are launching this week — a new product, a major feature, a v2 — and need launch-day copy across X, LinkedIn, ProductHunt, your email list, and possibly Reddit, Hacker News, and an in-app banner. Each surface has its own format and tone, but the underlying story is the same.
When AI is the right tool
- You are a solo founder or a 2-3 person team without dedicated copy resources.
- You have a strong product story and need help porting it across formats.
- You launch frequently and want a repeatable pipeline.
- You want platform-native phrasing rather than copy-paste sameness.
When not to rely on AI alone
- Headline launches at large companies where PR, legal, and brand teams must sign off.
- Categories where claims need fact-checking against benchmarks or studies.
- Sensitive launches (privacy, security, financial) where wording must be precise.
- Any post that quotes a partner or customer — verify the quote with the source.
What to feed the AI
- A 1-paragraph product brief: what it is, who it is for, what it replaces.
- The single sharpest hook (“we cut signup from 6 minutes to 30 seconds”).
- 2-3 customer quotes (real, with permission).
- The ProductHunt or launch URL.
- Founder voice samples (3-5 past posts that performed well).
- Your forbidden words list (“revolutionary”, “game-changer”, any emojis you hate).
Copy-ready prompt
You are a launch-day copywriter. Produce platform-native copy from one brief.
Brief:
{product_brief}
Audience: {audience}
Sharpest hook: {hook_one_liner}
Launch URL: {launch_url}
Customer quote (verified): {quote}
Founder voice samples: {voice_samples}
Forbidden words: {forbidden_list}
Output, in order:
1. X thread, 5 tweets. First tweet ends with a one-line hook, not a question. Tweet 2 = the problem in their words. Tweet 3 = the shift. Tweet 4 = a single concrete metric or quote. Tweet 5 = CTA + URL.
2. LinkedIn post, 180-220 words. Opens with a personal story line, not a product claim. Includes 1 specific number. CTA at the end.
3. ProductHunt: tagline (60 chars max) + 260-character description + first-comment from maker (150 words).
4. Email subject line (40 chars max) + 180-word email to existing users.
5. One-line in-app banner copy (60 chars max).
Do not reuse the same opening sentence twice across surfaces.Recommended output structure
Five distinct artifacts in one response, each formatted to fit its platform. A short “what’s reusable” footnote at the end lists the lines you can save for next launch.
How to check the output
- Read the X thread on a phone in dark mode — does tweet 1 stand alone if no one reads tweet 2?
- LinkedIn: does it start with a human, not a product?
- ProductHunt: is the tagline understandable to someone who has never heard of you?
- Email: would your most engaged user open it based on the subject line alone?
- Send all five to a friend not in your industry. Ask them to summarize what you launched.
Common mistakes
- Copy-pasting the same paragraph across all five surfaces.
- Leading with company-speak instead of a problem the reader recognizes.
- Forgetting the URL or putting it in tweet 1 (X deboosts external links there).
- ProductHunt copy that does not include a clear “different from X” line.
- No follow-up plan — launch day is day one, not the whole campaign.
Next steps to keep improving
After launch, save the post with the highest engagement per platform into a swipe file. Feed those as exemplars next time. Build a one-page checklist of “must include” elements per surface — over time, you stop relying on AI to remember them.
Practical depth notes
For AI Product Launch Copy: One Brief, Platform-Native Copy for Launch Day, the difference between a usable AI result and a generic one is the input packet. Give the model the audience, the current draft or raw material, the desired format, the decision you need to make, and two examples of what good and bad output look like. Ask it to preserve facts first, then improve structure or wording second.
After the first response, do a separate review pass. Look for missing constraints, invented details, weak calls to action, and language that sounds plausible but does not match the real situation. The best final output should be easy to use immediately: clear owner, clear next step, and no hidden assumption that someone else has to untangle.
FAQ
- Should I launch on multiple platforms the same day? Yes for the post; stagger replies and engagement over 72 hours.
- Do I need a separate ProductHunt strategy? Yes — PH rewards specificity, social proof, and maker presence in comments.
- Should I write before the launch or day-of? Draft 3 days early, refine 24 hours out, post day-of.
- What if my launch fails? Treat it as data. Most products take 2-3 launches to find traction.
- What about physical product visuals — packaging mockups, hero shots? Different prompt shape — see an AI packaging idea workflow and a structured product-image prompt.
