Write a one-liner people can search for
Your one-liner is not a tagline. It is the phrase a stranger would type when they need you. Here is how to write one that matches real posts.
Most one-liners are written for a homepage. Yours should be written for a search box.
Use the buyer's words
People do not search for "AI-powered release intelligence." They search for "auto changelog from GitHub." Borrow phrasing straight from the threads you want to show up in.
Name the who and the what
A good one-liner fits this shape:
<thing it does> for <who it is for>
e.g. Changelog widget for small SaaS teamsTest it against real posts
Paste your one-liner into the First10 demo. If the matches look like your customers, you are done. If not, swap one word and run it again.
