ABOUT
About
We build free tools that give you a quick, sourced answer when a household or everyday question comes up.
Why we make these tools
Instead of comparing several blog posts, you can type your numbers into a calculator or search a list and get the answer with its source. There are 108 tools in English so far, and none of them needs an account.
Calculations run in your browser. We do not send what you type to our servers.
How we work
- Where a fact comes from a source, we link to it and show the date we last checked.
- When a result depends on an assumption or varies by region, we say so next to it.
- Ads are kept visually separate from the content.
- We test with keyboards, screen readers and real phones, not only automated checks.
- English pages are written for English readers, not machine-translated word for word.
