Who's Behind Pocket Book Simulator?
It all started with a simple, frustrating situation:
I had just finished writing my first novel in a .txt file... and had no idea how it would look printed in a real pocket book. How many pages would it be? Would the text be cramped or too spaced out?
Searching Google, I only found paid templates, complicated configurations, or subscription services. I thought: "This should be easier".
I decided to create a simple emulator that shows text at the real size of a pocket book (10.7 × 15.7 cm), with no complications, no ads, and—most importantly—without anyone else seeing your file.
What started as a personal tool is now here for anyone who wants to preview their manuscript before printing it or having it professionally laid out.
Non-profit, no tracking, no personal data.
Just a free, open, and 100% private tool.
