Idea: Text Diff Viewer

[InzeeraZakariah]

Tool Name

Text Diff Viewer

Proposed Filename

text-diff-viewer.html

Category

Text & Content

Description

A tool that compares two blocks of text side by side and highlights the differences
between them — additions, deletions, and changed lines/words. Useful for developers
comparing code snippets or config changes, writers comparing document revisions, and
anyone who needs to spot what changed between two versions of text without using a
full version control tool.

Key Features

• Two side-by-side input panes (original vs. changed text)
• Line-by-line diff highlighting (added, removed, unchanged lines)
• Word-level highlighting within changed lines for finer granularity
• Line numbers on both panes
• Toggle between side-by-side and unified (inline) diff view
• Character/line/word change summary (e.g. "+12 -4 lines")
• Copy diff result / export as plain text
• Dark mode support

Suggested Difficulty

Medium
