Free tools

Small tools that work something out and then get out of the way. Everything runs in your browser, nothing is sent anywhere unless you choose to send it, and none of them will tell you something a web page has no business telling you.

What these are

Each one answers a question people are already asking, does the part that is genuinely mechanical, and then stops. None of them pretends the mechanical part was the hard part.

That is the line they are built along. A tool can show you what a test looks at; it cannot weigh your situation against it. It can multiply a footprint by a pitch factor; it cannot see what is under the shingles. Where the useful work ends, the page says so and offers you a conversation rather than a conclusion.

Nothing you type leaves your browser

Every one of these runs entirely on your own device. There is no account, nothing is stored, nothing is transmitted, and the pages have no way to transmit it — they are working out arithmetic in front of you, not sending it somewhere to be worked out.

That matters more than it sounds. These tools handle payroll details and the dimensions of somebody's house. At the end of each there is a link that carries a short summary of the result — no names, no contact details — into the guided intake, if you want the office to see it. You choose whether to follow it, and you can read exactly what it says first.

More to come

Two more are planned: what an employee actually costs beyond the salary, and a short project brief worth having ready before the first call.

The ones that rely on figures which move — rates, thresholds, the numbers that change every January — will show you the date each figure was checked and let you edit every one of them, because a prefilled number that has quietly gone stale is more misleading than an empty box. The two here have no such figures in them at all, which is why they came first.

Or skip the arithmetic and just ask.

The office answers within one business day.
