About WikiSolutions

WikiSolutions is a small, focused set of 16 calculators and converters — things like a mortgage and paycheck calculator, a BMI and calorie estimator, a JSON formatter, a QR code generator, and unit and color converters. It's built and maintained by Haiscent LLC, and it exists because most calculator sites bury a simple formula under walls of unrelated content, ads that cover the input fields, or a multi-step sign-up flow. WikiSolutions does the opposite: every tool loads instantly, runs entirely in your browser, and shows its work.

Concretely, "runs in your browser" means no tool on this site ever sends the numbers, text, or files you type into it to a server. The paycheck calculator computes your withholding client-side; the JSON formatter parses and re-serializes your data with the browser's built-in JSON.parse/JSON.stringify; the QR generator renders the matrix locally as SVG. Nothing is logged, stored in a database, or used to train anything. See the privacy policy for the specifics of what little data (cookies, aggregate analytics) is involved in running the site itself.

Each tool page also explains the method behind the number it gives you — the amortization formula behind the mortgage calculator, the Mifflin-St Jeor equation behind the BMI calculator's calorie estimate, the compounding math behind the compound interest tool — with a worked example, so you can verify the calculation instead of trusting a black box. If you spot an error in a formula or have a tool you'd like to see added, you can reach us through the contact page.
