About Jurepi
Everyday tools, all in one place.
Why we built it
As the gap in access to AI's benefits keeps widening, we wanted to use that same technology to build tools that genuinely help everyone who visits—completely free. Tell us what tool or feature you need, and we'll build it and add it, one at a time.
What is Jurepi?
Jurepi is a free online tool hub designed to make everyday tasks simpler. Whether you need to make a fair decision for your group, keep a daily reflection journal, or find quick answers to common problems, Jurepi has you covered. No sign-up, no login, no hassle—just open a tool and get started.
Privacy first
We don't collect your personal information. When you use Jurepi tools, your data stays on your device. Everything you enter—names in the ladder game, reflections in the journal, calculations—stays safely in your browser's local storage and never leaves your computer. Your privacy is our priority.
Tools for every need
We start with tools that solve real problems: a fair lottery game for making group decisions, and a daily journal for self-reflection. More tools are coming soon across categories like math, text, conversions, and fun. Check back often as we expand what Jurepi can do for you.
Why is it free?
Every Jurepi tool is, and will stay, free. We cover our running costs with the ads shown on the page. To keep those ads from getting in the way, we reserve their space and height in advance so the page never jumps around—and we never sell your personal information. You can turn ad and analytics cookies off or on anytime via 'Privacy settings' in the footer.
Built in the open
Jurepi is built and run by one person—Jurepi, a developer who loves books. New tools, improvements, and notes on design and engineering are shared on the blog. Follow along to see how Jurepi grows.
Built with AI, in the open
Jurepi's tools and content are built with the help of modern AI—a way to turn ideas into working tools quickly and to ship useful features more often. The process and the result aren't hidden: the source code is public on GitHub, so anyone can see how a tool works and suggest improvements.
How each tool is made
Every tool starts from a real frustration. The math is verified with tests first, then checked by hand on real screens and phones before it goes live. When something's wrong, it gets fixed quickly rather than left alone. If you spot anything off while using a tool, let us know—that feedback is where the next improvement begins.
Questions or ideas?
If you have feedback on a tool, found a bug, or need a new feature, send an email anytime—we usually reply within a few days. Common questions and how-to notes are collected near the bottom of each tool page, so open a tool and take a look together.
