Have you ever had two versions of a document or code snippet and wondered: “What exactly changed?” Our Text Difference Highlighter answers that question instantly. It’s a smart online tool that compares two pieces of text or code and highlights the differences between them in real time—no downloads, no signups, just results.
Our tool works by scanning both versions—Text A (Original) and Text B (Modified)—and comparing them line by line, word by word, or character by character (depending on the logic). Once it detects any insertions, deletions, or changes, it highlights them with intuitive color codes that make it easy to spot differences at a glance.
This visual cue system helps you quickly understand what's changed and what hasn't—saving you time and reducing the chance of errors.
Whether you’re a developer, writer, editor, student, or project manager—this tool is for you. Here’s how different people benefit from it:
