About ToolBoxGenie

Why the site exists

Small tasks eat a surprising amount of time. Working out what a loan really costs, checking an essay against a word limit, pretty-printing an API response, converting a recipe from cups to grams. Each one takes a minute, and each one usually means finding a website covered in pop-ups that wants your email address first.

ToolBoxGenie started as a straightforward answer to that: a clean page, a tool that works immediately, and an explanation of the method underneath so the number can be checked rather than merely trusted.

How the tools are built

Everything runs client-side. When you open the JSON formatter, the parser is downloaded to your browser and runs there. When you work out an EMI, the entire amortisation schedule is built in the tab. No calculation touches a server we operate, and no tool on the site sends what you enter anywhere — there is no upload endpoint to send it to.

That architecture has three consequences we care about. It is faster, because there is no round trip. It is private, because there is nothing to store. And it keeps working offline once the page has loaded.

How content is written

Every tool page includes a worked example, a step-by-step guide and a set of genuine questions with real answers — the difference between markup and margin, why a 20% discount is not undone by a 20% increase, why a JSON parse error usually points one line past the actual mistake.

Where a convention is contested, the page says which one it uses. Where a tool has limits, the page says so: BMI does not work for athletes, a regex cannot parse HTML, and a business-day count cannot know your local public holidays.

How the site is funded

ToolBoxGenie is free and supported by advertising served through Google AdSense. Google selects and positions the ads automatically; they are labelled as advertising, and none of them are styled by us to resemble site content or a tool control.

Automatic placement means we do not decide where each ad lands, so if one ever sits inside a tool’s controls, covers something you were reading, or looks like part of the interface, tell us. That is a placement we will exclude, and reports are the fastest way we find them.

We also use Google Analytics to see how many people visit and which tools get opened, which is how we decide what to build next. It measures pages and traffic sources; it cannot see what you type into a tool, because that never leaves your browser. We sell nothing to anyone, and we hold no accounts or user records of our own. The privacy policy sets out exactly what our advertising and analytics partners do and do not receive, and how to opt out of each.

Who publishes this site

ToolBoxGenie is written and maintained by Sidhin, working alone. It is an independent project, not a company product, and there is no editorial team behind it — one person builds each tool, tests it against worked examples, and writes the explanation that sits under it.

That is the whole of the claim. This site does not present itself as a medical, legal, tax or financial authority, and you will not find a byline here claiming qualifications it cannot show you. What it offers instead is checkable work: every calculator states the formula it uses, the money and health tools link to the primary source that defines the method — the WHO fact sheet, the paper the equation comes from, the tax authority that publishes the rates — and the arithmetic behind 305 tools is tested on every build against independently computed expected values. Trust the sources and the working, not the author.

It is not operated by, affiliated with or endorsed by any of the organisations whose formats, standards or services its tools work with — the JSON and PDF specifications, Google, or anyone else. Tool names describe what a tool does; they are not claims of any relationship with a trademark holder.

There is no support desk and no ticketing system behind the site. Mail sent to sidhin.p.s2020@gmail.com reaches the person who maintains it, and the contact page explains what to include so a reply is useful.

What is next

The site currently offers 305 tools across 6 categories, and more are in the works. Tools are published only once they work properly and have real supporting content — a bare calculator behind a promising title is not worth anybody’s click, so nothing here is a placeholder.

Suggestions for new tools are genuinely welcome. The contact page is the fastest way to reach us.
