Semantic Diff — Compare Meaning, Not Just Text
Traditional diff identifies literal text changes. DiffFind adds optional semantic analysis to help explain whether those changes affect meaning. Semantic analysis complements deterministic comparison.
How it works
Add semantic analysis.
Use optional AI analysis to explore the meaning and impact of the changes.
Review the source evidence.
Read the explanation alongside the original text and deterministic diff.
See an example
Illustrative examples of the feature.
Different wording, essentially the same meaning
BEFORE
The service retries the request three times before failing.
AFTER
Before returning an error, the service makes three retry attempts.
The wording changed substantially, but both versions describe three retries before failure.
One character, a significant behavior change
BEFORE
Requests timeout after 30 seconds.
AFTER
Requests timeout after 3 seconds.
Removing the “0” changes the timeout from 30 seconds to 3 seconds: one character changes how long a request may wait.
Why Semantic Diff is useful
Deterministic comparison establishes what changed. Semantic analysis explains what it means.
This helps you distinguish rewrites from changes to behavior, obligations, or requirements. Review AI explanations against the source when a detail matters.
Start with Text Compare for precise lexical changes, or compare documents with PDF Comparison and Excel Comparison.
