The Problem

As a developer, I constantly needed to:

• Format messy JSON from API responses
• Convert text between different cases
• Clean up CSV data
• Remove duplicate lines
• Encode/decode URLs
• And dozens of other text processing tasks

Every time, I'd Google for a tool and end up on sites that:

• ❌ Were covered in ads
• ❌ Required email signup
• ❌ Sent my data to their servers (privacy concerns!)
• ❌ Had slow, bloated interfaces
• ❌ Didn't work offline

I got tired of it. So I built CleanTextLab.

What is CleanTextLab?

CleanTextLab is a collection of 12 powerful text processing tools, all in one place:

Once you load the page, you can use it without internet. Perfect for working on planes, trains, or anywhere with spotty connection.

🎨 Beautiful & Fast

Clean interface with 10 themes (including dark mode). No bloat, no ads, just tools that work.

🆓 Free Forever

All 12 tools are completely free for personal use. No hidden fees, no paywalls for basic features.

🚀 Pro Features (Optional)

Need more? Pro adds:

• API access for automation
• Higher processing limits

Just $9/month - but most people will never need it!

Built for Developers, By a Developer

I built CleanTextLab using modern web technologies:

• Next.js 15 with React Compiler
• TypeScript for type safety
• Clerk for authentication
• Microsoft Clarity for privacy-friendly analytics
• Sentry for error monitoring

The result? A blazing-fast, reliable tool suite that I use every single day.
