Text diff

Compare runs in the same two panels: removed lines tint red on the left, additions green on the right, unchanged lines aligned across both.

When line-by-line diff is enough

A simple diff is often the fastest way to compare two versions of a policy, changelog, or email draft. Line-based highlights are especially useful when entire sentences moved, because they help you spot added or removed wording without reading both copies from top to bottom.

Making the comparison useful

If you are reviewing contract notes or release text, keep the original and revised versions short and focused. That makes the highlights easier to interpret and reduces noise from unrelated formatting changes that would otherwise bury the actual edit.

When line diff is enough

Config file reviews, changelog edits, and legal clause comparisons usually change whole lines — word-level diff is unnecessary overhead.

How text diff works

Paste an original and a revised version. The tool splits lines and walks both sides to show additions and deletions similar to a lightweight patch view.

Best for logs, configs, emails, or drafts where line granularity is enough.

Privacy

Both texts stay local; nothing is uploaded for comparison.

Quick start

  1. Paste original text — Put the baseline version in the first field — a config, email, or paragraph.
  2. Paste revised text — Add the updated version in the second field.
  3. Review highlights — Added and removed lines are highlighted so you can spot changes quickly.
