Questions
What is a launch post checker
A free tool that reads your product or feature launch announcement before you publish it. It scores the post, email or changelog intro on 11 rules, and each rule comes from a real launch in our library that shows it working.
How does the launch post checker score my announcement
It runs 11 rules in your browser: what people can do now, the problem it solves, what people asked for, the main benefit, one real use, one line per new part, exact details, who gets it and when, where to find it, what it works with and plain words. Each rule has a weight. A pass earns its points, a near miss earns half, and the score is the share of points earned.
What should a product launch announcement include
What people can do now, the problem it fixes, one real use, who gets it and when, and exactly where to find it. Then add one visual. Our guide on how to announce a new feature shows each step with real launches.
Where do the rules come from
From the launches in Launch Posts on X That Worked and How to announce a new feature. Every fix links to the launch that shows the rule, so you can see it before you copy it.
Does it work for launch emails and changelogs
Yes. Paste the subject and first lines of the email, or the top of the changelog entry. The same rules apply: what changed, why it matters, who gets it and where to find it.
Is the launch post checker free
Yes, free and no signup. No. There is no login and nothing is saved. Everything runs in your browser.
