Compare two documents or versions and highlight the differences
Puts two documents or two versions side by side and lists every meaningful change, addition, and removal, ranked by impact.
The prompt
Compare the two documents below and show me what is different.
Document A (older version, or first document): [PASTE]
Document B (newer version, or second document): [PASTE]
What these are: [e.g. "v2 and v3 of our project plan", "two vendor proposals", "last year's and this year's policy"]
What I care about most: [optional - e.g. dates, money, scope, obligations, responsibilities]
Return:
1. Summary - the 3-5 differences that matter most, in plain words.
2. Change table: | # | Section / topic | Document A says | Document B says | Type (added / removed / changed / moved) | Impact (high / medium / low) and why |
3. Numbers, dates, and names - every figure, date, deadline, owner, or threshold that differs.
4. Silent changes - wording shifts that change meaning (e.g. "must" to "should", "will" to "may", narrowed or widened scope).
5. What's the same - one line confirming which sections are unchanged.
6. Questions to raise - changes that seem unexplained or inconsistent.
Rules:
- Ignore pure formatting and typo fixes unless I ask; list them in one line at the end.
- Quote exact wording for important changes so I can find them.
- Don't judge which version is "right" unless I ask; describe the difference and its effect.
- For legal contracts, have a qualified professional review the final comparison.
