Text Compare

About This Tool

So, you’ve got two chunks of text and you’re trying to figure out what’s different between them. Maybe it’s code, maybe it’s a document you edited last week, or maybe your coworker sent you a “slightly updated” version of something and you just want to see what actually changed. That’s where Text Compare comes in.

It’s not fancy. No animations, no login walls, no “premium features” behind a paywall. You paste in your two texts, hit compare, and it shows you the differences—line by line, word by word, sometimes even character by character. Simple. Fast. Honestly kind of satisfying when you finally spot that one typo that’s been bugging you.

I built this because I kept needing it. Every time I’d tweak a config file or rewrite a paragraph, I’d end up opening two browser tabs and squinting at the screen like a detective. There had to be a better way. So I made one.

Key Features

• Side-by-side comparison with clear highlighting of added, removed, and changed text
• Works with plain text, code, JSON, HTML, markdown—basically anything you can type or paste
• No files uploaded. Everything happens in your browser. Your data doesn’t leave your machine
• Line numbers for easy reference, especially useful when debugging code
• Toggle between word-level and line-level diff views depending on how detailed you need to be
• Dark mode because, let’s be real, your eyes deserve a break
• Keyboard shortcuts for power users (because mouse fatigue is real)
• Responsive design—works on your phone if you’re into that kind of thing

FAQ

Wait, does this save my text anywhere?
Nope. Nothing gets sent to a server. The whole comparison runs right in your browser. Close the tab, and it’s gone. Your secrets are safe.

Can I compare really long files?
Sure, but don’t go dropping a 50,000-line log file and expect it to be snappy. It’ll work, but your browser might get grumpy. For anything over a few thousand lines, you might want to use a dedicated diff tool. This one’s best for everyday stuff—configs, emails, code snippets, that kind of thing.
