Compare Two Texts
Drop two pieces of text side by side and get the literal difference between them — what was added, removed, and reworded.
Overview
Comparing two texts by eye is slow and error-prone; a diff does it instantly and completely. This loads two short, similar messages and shows precisely where they diverge — a changed weekday, an added clause — with the moved words marked. It is a mechanical comparison: it shows the difference and leaves every opinion to you. The point is to see the change clearly, not to be told what it means or which side to prefer.
Workflow
-
Paste the two texts
Two versions, drafts, or messages to compare.
-
See where they diverge
Added, removed, and reworded parts marked clearly.
-
Read it yourself
The diff shows the change; the interpretation is yours.
Why This Works
- A diff finds every divergence faster and more completely than the eye
- Inline marks show added, removed, and reworded content at a glance
- Mechanical output leaves the judgment entirely to you

Not for
- Scoring or ranking the two texts — that's the Prompt Comparator
- Analyzing a prompt revision — that's the Prompt Version Diff
