CLARITYKIT

About ClarityKit

Useful tools, clear methods, fewer distractions.

Make everyday decisions easier

ClarityKit is an independent collection of free calculators, converters and utilities. Each tool is built around one job, with the working controls first and the explanation close at hand.

How the tools are built

Calculation logic is separated from page content and checked with automated examples and boundary cases. The interface, code and explanatory content were developed with AI assistance. We do not claim independent expert review or medical certification.

Every published tool includes its method, a practical example and relevant limitations. Where an established health or financial reference is used, we link to it. Results are rounded for display while intermediate calculations retain precision.

Your inputs stay local

Calculations run in your browser. Currency tools request only a currency pair and optional date from Frankfurter’s ECB rate API after you select Calculate. Amounts, fees, pasted text and passwords are not sent to that service. Shared input links are optional and deliberately unavailable for health, pasted text and generated secrets.

A library built to grow carefully

New tools should solve a distinct problem and pass the same accuracy and usability checks. We favor a smaller useful library over repeated or unfinished pages.
