About Text Compare
Line-by-line text diff
Text Compare keeps the input as plain text and highlights line-level additions, removals, and modifications. It is useful when you need to review notes, code snippets, generated output, or configuration fragments without a format-specific parser.
Controls for noisy diffs
The comparison view includes options such as ignoring whitespace and collapsing unchanged sections. These controls help you focus on meaningful edits when formatting or large unchanged blocks would otherwise dominate the result.
Quick local review
All comparison work happens in the browser, so you can paste temporary snippets or draft text for a quick check. For structured data such as JSON, YAML, or TOML, use the dedicated compare tools when you need parser-aware structural diffs.
