Shop owners type a promo and get a clean printable window sign in a minute.

The idea

Small shops need quick signs for sales, holiday hours and new items but have no designer. Type what you want to say and the app writes short sign copy and lays it out in a few clean templates ready to print on letter or poster size.

Who it is for
Retail shops, cafes and salons without a designer
How it makes money
Pay per sign pack or small monthly plan
Suggested stack
Next.js, MySQL, Tailwind, hosted on a small VPS

Your first AI prompts

Paste these into Claude, Cursor or Lovable, in order. Check that each one works before moving on.

PROMPT 1 OF 3

Build a web app called Window Sign Maker. Start with a single page where the user enters the message, shop name, brand color and chooses a size (letter, tabloid, 18 by 24).

PROMPT 2 OF 3

Use an AI model to turn the message into a headline under 6 words, a subline under 12 words and an optional small print line. Render the result in 5 HTML templates with big readable type, and let the user edit the text inline and pick a template.
