Product launch post generator for X, LinkedIn and Product Hunt
Paste the URL of what you are launching. John, Venturehand’s AI agent, reads the page and writes your launch-day copy from it: an X post with a short thread, a LinkedIn post, and a Product Hunt tagline, description and first comment, each held to the platform’s character limit. The tagline and the X post appear here; the rest arrives as a PDF at the address you give. No account, no card.
Free, no account. We read your public page and keep the URL and the result for a day, so a repeat visit is instant and you can email yourself the full set as a PDF.
Copy for three places, written only from what your page says and held to each platform’s character limit. The tagline and the X post show here; the rest comes as a PDF to your inbox:

What a good launch post does on each platform
The facts stay the same across platforms. The length, the shape and the first line change.
X280 characters, and a link counts as 23
One post that says what you launched and what it does, in words a stranger already uses, then a short thread under it: how it works, one or two concrete features, what is free. The first line carries the post, because it is often the only line read in a fast feed.
LinkedIn3,000 characters
A longer post in short paragraphs, from your own profile. LinkedIn cuts the post after the first two or three lines and shows “see more”, so the opening has to stand on its own: the problem you solved, or what is live today, never “I’m excited to announce”.
Product Hunt60-character tagline, 260-character description
Three pieces: a tagline that says what it is (your product’s name already sits next to it, so the tagline should not repeat it), a description of who it is for and what makes it different, and the maker’s first comment, posted as soon as the launch goes live.
Launch post character limits
What each platform lets you post, and what the tool holds each piece to.
| Platform | Piece | Limit | Note |
|---|---|---|---|
| X | Post or reply | 280 | Any link counts as 23 |
| Post | 3,000 | Cut after 2–3 lines | |
| Product Hunt | Tagline | 60 | Shown beside your name |
| Product Hunt | Description | 260 | Under the tagline |
A worked example
A made-up product, so the facts are easy to check: two lines from its page, and what each platform gets from them.
The page says
- “Turn each Stripe payout into the invoice your accountant asks for.”
- “Free for your first 20 invoices a month.”
- X post132 / 280
- Today I'm launching Ledgerly. It turns each Stripe payout into the invoice your accountant asks for. Free for your first 20 a month.
- Product Hunt tagline51 / 60
- Invoices your accountant wants, from Stripe payouts
- LinkedIn opening lines
- Your accountant asks for invoices. Stripe gives you payouts. Today I'm launching Ledgerly, which turns one into the other.
What it will not write: “Every month I rebuilt invoices by hand, so I built Ledgerly.” That story may be true, but the page never told it. Add it yourself if it is; in the Product Hunt comment the tool leaves a gap in [brackets] where it belongs.
Common launch post mistakes
Each one is something the tool checks for, and something to check yourself before you post.
- 01
Opening with the announcement instead of the product
“Excited to announce” tells a reader nothing they can use. Say what is live and what it does in the first line.
- 02
Claims your page cannot back
A user count, a percentage or a customer name that is not on your page invites the first reply to ask for proof. If your page does not say it, the post should not either.
- 03
The same text on every platform
A 280-character X post pasted into LinkedIn reads like a headline with nothing under it, and a LinkedIn post cut down for X loses its point. Each platform gets its own length and shape.
- 04
Emoji walls and hashtag strings
Ten emoji and five hashtags make a post look generated. On X and in a Product Hunt comment, plain sentences do the work.
- 05
A tagline that repeats the product name
Product Hunt already shows the name next to it. Spend the 60 characters on what the product does.
- 06
No first comment ready
The maker’s comment is where people ask questions on launch day. Have it written before the launch goes live, with the gaps only you can fill already filled.
How the posts are written
Built so that nothing goes out under your name that your page does not say.
- John, Venturehand’s AI agent, reads your public page and first lists the facts a post can stand on, each with the exact line from your page that states it. A line we cannot find on your page is dropped rather than shown.
- Every number in the copy is checked against your page. A figure your page never states is replaced by [number] for you to fill or cut, so nothing goes out under your name that you did not claim.
- Every piece is held to its platform’s limit, counted the way the platform counts it, and the product link is added by our code, so it is always the page you pasted.
- Launch clichés (“excited to announce”, “game-changer”, “supercharge”), emoji and hashtags are filtered out. Where only you know something, such as your name or why you built it, the copy leaves a gap in [brackets].
What this can't do
Worth knowing before you post anything it wrote.
- It writes from your page alone. It does not know your story, your users or your numbers unless the page states them, so the posts are drafts to make yours, not finished copy.
- It cannot tell you when to launch or whether a post will do well. Nothing here is a prediction of reach.
- It reads one page at a time, in English, and cannot read pages behind a login, a paywall or a strict bot check.
- It is written by an AI model. AI can be wrong: read every post aloud once before it goes out.
Questions about launch posts
What should a product launch post say?
What is live, what it does, and who it is for, in the first line, followed by one or two concrete details a reader could not guess: how it works, what it costs, what is free. End with one question a reader can answer in a reply. Leave out anything your product page does not back up.
How long can a Product Hunt tagline be?
60 characters. The description under it can be 260. Product Hunt shows your product's name beside the tagline, so the tagline should say what the product does rather than repeat the name.
What is a maker's first comment on Product Hunt?
The comment the maker posts on their own launch as soon as it goes live: who they are, why they built the product, what it does in two or three lines, what is free, and a question for the people reading. It is where most launch-day conversation starts, so write it before the launch.
Should I post the same launch announcement on X and LinkedIn?
No. Same facts, different shapes: X takes a short post with a thread under it, and LinkedIn takes a longer post in short paragraphs whose first lines work before “see more”. This tool writes each one for its platform from the same page.
Is the launch post generator free?
Yes. No account, no card. The Product Hunt tagline and the X launch post appear on the page; the thread, the LinkedIn post, the Product Hunt description and the first comment come as a PDF to the email address you give. There is an hourly limit per visitor because each run costs us a model call, and the result for a page is kept for a day, so pasting it again shows the same posts at once.
Is this written by AI?
Yes. The posts are written by John, Venturehand's AI agent, from the text of your public page. Our code checks every number against the page, holds every piece to its platform's limit and filters launch clichés, but AI can be wrong: read each post before you publish it.
Do you store my URL or the posts?
We keep the URL you paste, without its query string, and the result for a day, so a repeat visit is instant and you can email yourself the full set as a PDF. The PDF is emailed only if you ask for it, and you are added to Venturehand's email list only if you tick the box on that form.
