A little less complexity.
A lot more clarity.
ARZENTIQ makes small, dependable web utilities for people who have a job to finish. Each one takes what you already know, does one job you can check — a calculation, a conversion, a lookup, a plan — and hands you something you can use in the next step of your work.

How every ARZENTIQ utility works
One job, one checkable result
Clear inputs with their units where they apply, editable assumptions, and a result you can trace back to what you entered — whether it is calculated, converted, looked up, or planned.
Runs in your browser
Nothing you enter is uploaded, and nothing is kept on our servers. When one utility hands a value to another it stays in this tab until it is read. No accounts, no cookies, no third-party scripts. See the privacy page
Honest about limits
Every utility says what it assumes, where its data comes from, and what it is not. Verify before you act on a result that matters.
Built for real work
Each utility shows its method and assumptions so you can check the result before using it. If you use one on a real job, tell us what happened — especially what looked wrong. More on the about page.
