How It Works

1

Install

Add from Chrome Web Store. No account needed.

2

Click

Click the extension icon on any page.

The Problem

Manually retyping text in a different case is tedious and error-prone

Online converters require copying text, opening a new tab, and pasting back

Developers constantly need snake_case or camelCase conversions during coding

Frequently Asked Questions

What about special characters and accents?

Unicode-aware — accented characters convert correctly across all supported locales.
