For code reviews, split view with line numbers is usually easiest. When you only want to inspect edits, turn on Hide unchanged to reduce noise.
Use this tool when
These are the practical situations where this workflow usually earns its keep.
You want to see both grouped change blocks and smaller inline wording changes.
You need a cleaner way to explain what changed before the comparison moves into a ticket, PR, or handover.
Documentation and runbook review
A side-by-side text diff helps teams verify wording and instruction changes before they publish or operationalize them.
Prompt and policy iteration
Small changes in prompts, standards, or response templates can have outsized downstream effects, so a readable text diff shortens that review cycle.
Operational handover and note cleanup
When one person rewrites or updates a note set, the diff gives the next reviewer a faster path to what actually changed.
Common mistakes to avoid
These are the checks that usually keep the output useful instead of misleading.
Spending time on every wording difference even when only a few changes affect behavior or meaning.
Comparing already-summarized versions instead of the original source text when the review is high risk.
Using the diff without recording the actual conclusion or next action.
Learn how to use this tool
Compare two text blocks in a review-friendly layout so edits, insertions, removals, and inline wording drift are easier to discuss.
