I used to work at a convenience store in Japan.
The owner was always chasing something — answering the phone in the middle of an order, jumping on the register in the middle of the call. And in between, they'd sit at the office computer, fighting with a sign that said “FRIED CHICKEN ___ YEN”. Make the font bigger and it runs off the page. Change the printer settings, and now it's too small.
Friends who ran their own shops kept asking me to make signs for them, too. I was glad to help. But every time, I thought: what people really need isn't someone to ask — it's a way to make one themselves, right now. No design skills, no special software.
So I built one. Type your text. One letter per page, as big as it gets. That's all it is — really, that's all.
For the first three years after launch, it earned exactly zero. No ads, no sign-ups, no fees. Call it stubbornness — I just wanted to know one thing: is this genuinely needed?
The answer came. Over 70,000 PDFs have been created — by shop owners, teachers at kindergartens and schools, crews at construction sites, and someone decorating for a family birthday. Four sheets spelling “OPEN”, a sports-day banner, a “SAFETY FIRST” notice, a “HAPPY BIRTHDAY” strung across the living-room wall — each one protecting ten minutes for somebody like that owner of mine.
