About these tools

This site is a collection of small, free tools for everyday text, writing and developer tasks. Each tool does one job, explains how it works, and runs entirely in your web browser.

Why everything runs in your browser

When you paste text or data into a tool here, the calculation happens on your own device with JavaScript. Nothing you type is uploaded to a server, stored, or logged. That keeps your data private and keeps the site fast and free to run.

How the tools are made

We use AI assistance to write code and drafts, and every tool goes through automated tests and human review before it is published. The details are on How we build our tools.
