Text Cleanup Center — Sain

Text Cleanup Center is a lightweight Firefox extension that provides a collection of practical tools for formatting, cleaning, and organizing text directly inside the browser popup.

Users can inspect text statistics, normalize spacing, remove duplicate or blank lines, sort content alphabetically, and reverse line order using built-in offline utilities.

The extension is intended for lightweight productivity tasks, quick formatting workflows, and local text organization without relying on external services or cloud-based processing.

All functionality is executed locally using client-side JavaScript within the browser environment.
