I Built a Free Privacy-First Text Toolkit That Runs Entirely in Your Browser

After using dozens of online text utilities over the years, I noticed the same recurring problems:

• Too many ads and popups
• Slow interfaces
• Forced sign-ups
• Text being uploaded to remote servers
• Poor mobile experience

I wanted something different.

So I built TextCaret.

The idea

The goal was simple:

Build a collection of text tools that are:

• Fast
• Free
• Privacy-first
• Mobile friendly
• Easy to use

Most importantly, everything runs locally in your browser.

Your text never leaves your device.

Current features

TextCaret currently includes tools like:

• Word Counter
• Character Counter
• Reading Time Calculator
• Case Converter
• Remove Duplicate Lines
• Remove Empty Lines
• Find & Replace
• Reverse Text
• Base64 Encode/Decode
• URL Encode/Decode
• JSON Formatter
• Slug Generator
• Unicode Text Generator

More tools are being added continuously.

Technical approach

The project is intentionally lightweight.

• Vanilla JavaScript
• HTML
• CSS
• No backend required for the tools
• Instant processing
• Responsive interface
• SEO-friendly pages
• Structured data (Schema.org)

Because everything happens client-side, the website is extremely fast and no user text is stored.

Why privacy matters

Many online tools ask users to paste confidential content.

That may include:

• Contracts
• Source code
• Emails
• Reports
• Internal documentation

With TextCaret, the text stays inside your browser.

No uploads.

No accounts.

No tracking of your content.

What's next

I'm currently working on:

• More text utilities
• Better accessibility
• More language support
• Improved SEO resources
• Additional developer tools
