Text Compare
Compare plain text side by side in a lightweight editor-style interface built for everyday review tasks. This tool gives you two editable panes, synchronized line numbers, and Git-like visual diff colors that make additions, removals, and modifications obvious at a glance. It is useful for release notes, documentation updates, copy revisions, command snippets, and any workflow where quick text verification matters. You can enable auto-compare for continuous updates while typing, toggle sync scrolling for long documents, and copy either pane instantly. For cleanup workflows, built-in actions let you trim trailing spaces and normalize line endings before running comparison. The layout is responsive for mobile and desktop, follows SLR CORE day/night theming, and runs entirely in your browser with plain JavaScript for reliable compatibility across static hosting environments like S3 and CloudFront.

Text Compare FAQ
Is this useful for code or only plain text?
It works for both. Any line-based content can be compared effectively with this visual diff layout.
What does Normalize line endings do?
It converts CRLF/CR endings to LF on both panes so platform-specific newline differences do not cause noise.
Can I ignore letter case?
Yes. Enable the Ignore case toggle to compare text without case sensitivity.
Does this save my content?
No. Comparison happens locally in your browser and your text is not uploaded.
