Free tools that each do one job
A growing collection of free, single-purpose tools. No sign-up, no downloads, and every result shows where its data came from.

How this works
One tool, one question
Each tool answers a single question and stops there. If something needs two answers, it becomes two tools rather than one cluttered page.
Built on published data
Answers come from public datasets and documented formulas. Nothing is estimated or invented, and each tool names exactly what it drew on.
Nothing to sign up for
No account, no download, no paywall. Tools run in your browser and this site keeps no record of what you looked up.
How accurate these answers are
Every result shows the source it came from and the date it was retrieved, on the result itself rather than buried in a footer. If you want to check a figure, each tool links to the original record so you can look at it directly.
These tools are an interface to information that already exists. They do not add expertise, testing or opinion, and nobody here has inspected your property, your equipment or your situation. Published data has real limits — resolution, age, rounding and gaps in coverage — and each tool states its own limits plainly, including the inputs where it declines to answer.
Where a decision carries real cost or risk, treat these answers as a starting point and get the official record or a qualified professional opinion.
