Who’s behind Pocket Book Simulator?
It all started with a very simple and frustrating situation:
I had just finished writing my first full book in a .txt file… and I realized I had no idea what it would actually look like printed as a real pocket paperback. How many pages would it have? Would the text fit well? Would it look cramped or too spaced out?
When I searched Google, I only found paid Word templates, complicated setups, or ones that required subscriptions. So I thought: “This should be easier”.
I decided to create a simple emulator that shows the text at the exact real size of a pocket book (approx. 10.7 × 15.7 cm), no frills, no ads, and —most importantly— without anyone else seeing my file.
What began as a tool for myself is now here for anyone who wants to preview their manuscript, novel, short story, or any long text before sending it to print or professional layout.
No profit motive, no tracking, no personal data collected.
Just a free, open, and 100% private tool.
