Our Mission

Simplifying the complex. We create powerful, free, and accessible tools that genuinely help.

The Origin of Uselium

Uselium was born from a simple need that its founder, Jesús Castillo Rico, constantly encountered: the search for fast and reliable online utilities that weren't hidden behind a mandatory signup, a paywall, or a confusing interface.

What started as a personal solution for finance, marketing, and development tasks has evolved into this hub of tools. Our goal is to provide direct solutions to specific problems, without friction and with a focus on quality.
