About CleanTextKit

CleanTextKit is a free, privacy-first collection of browser-based tools for converting, cleaning, and formatting subtitles and transcripts.

Our Mission

We believe that simple, useful tools should be free and accessible to everyone. Whether you're a student cleaning up lecture transcripts, a content creator repurposing video subtitles, or a researcher preparing transcripts for AI analysis — our tools are here to help.

Why We Built This

Converting subtitles to clean text is a common but tedious task. Most existing solutions require uploading files to servers, installing software, or paying for subscriptions. We wanted to create something simpler: tools that work instantly in your browser, with no uploads, no sign-ups, and no costs.

Privacy First

All processing happens entirely in your browserusing JavaScript. Your files and text never leave your device. We do not collect, store, or transmit any of your data. This isn't just a feature — it's a fundamental design principle. No servers ever see your content.

How It's Built

CleanTextKit is a static website built with modern web technologies: Next.js, React, TypeScript, and Tailwind CSS. All subtitle and transcript processing is done client-side with custom-built parsing and cleaning functions. The site is deployed as static HTML/CSS/JS files, making it fast, reliable, and easy to host anywhere.
