What a launch tagline has to do
A tagline is the line under your product name on a launch board, a directory listing and often your homepage. It has one job: make a stranger understand what the product does fast enough to click. Most weak taglines fail the same way. They describe a feeling (“Work, reimagined”) instead of the thing (“Turn support tickets into a weekly bug list”).
A reliable pattern has three parts, and you rarely need all three:
- The job. A verb and an object: “Schedule posts”, “Track invoices”, “Find broken links”.
- The audience. “for freelance designers”, “for Shopify stores”. Naming who it’s for filters in the right people.
- The difference. “without a spreadsheet”, “in one click”, “open source”. One qualifier, not four.
How this generator works
You describe the product and the audience and pick a tone. We ask an open model (Llama 3.3 70B on Cloudflare Workers AI) for sixteen lines across different angles: the job, the outcome, the pain removed, the audience and the difference. We drop anything over 60 characters, duplicates and anything that asks for votes, then show up to ten with their character counts. If too few pass, we ask once more.
Picking the one you’ll use
- Cover the product name and read each line. Could a stranger tell what the product does? Cross out the ones they couldn’t.
- Check each claim is true today. “Automatic” means nothing to set up; “free” means free.
- Say the last two out loud to someone in your audience and ask them to explain the product back to you. Keep the one they explain best.
- Use the same line everywhere you launch that week, so people who see it twice recognise it. The product description generator writes the longer copy to go with it.
Honest limits
The model writes plausible lines, not tested ones. It doesn’t know your competitors, and it can make a claim sound bigger than it is, so edit anything that overstates. The real test is whether people click and sign up, which you’ll only see after launch.
