Little tools for everyday life

Not every calculation is about money or measurements. This hub gathers the everyday utilities, home helpers and just-for-fun tools that do not fit neatly anywhere else, from generating a strong password to scaling a recipe, checking a commute cost, or settling a curious what-if. Each one is free, quick and private.

Practical first, playful second

The utility and home tools are the ones you will likely reach for again, such as the password generator or the recipe scaler. The fun section is exactly that, a bit of light entertainment, so take those results in the spirit they are meant.

Private by default

Everything here runs in your browser. Whatever you type, including anything you generate, stays on your device and is never stored or sent anywhere.

Frequently asked questions

Is the password generator safe to use?

Yes. Passwords are generated in your browser and never sent anywhere. For best security, generate a long, unique password for each account and store it in a reputable password manager.

Are the fun calculators based on real science?

The playful tools, such as the rizz calculator, are for entertainment and are not scientific. Practical tools like the recipe scaler and commute cost use straightforward, reliable math.

Do these tools store what I enter?

No. Every calculator on this page runs entirely in your browser, so your inputs are not saved or shared.
