Five concrete examples of the Code Compare Tool in real use. Each one shows the situation, what you put in and what comes out, so you can copy the structure, swap in your details and adapt it this week.
Example 1: Spotting changes between two versions
The task: Spotting changes between two versions. You start from two code samples - the old version on the left and the new one on the right.. The tool returns a side-by-side diff with added, removed and changed lines highlighted., giving you a precise list of every edit between the two versions. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 2: Checking what a teammate edited
The task: Checking what a teammate edited. You start from two code samples - the old version on the left and the new one on the right.. The tool returns a side-by-side diff with added, removed and changed lines highlighted., giving you a precise list of every edit between the two versions. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 3: Comparing configuration revisions
The task: Comparing configuration revisions. You start from two code samples - the old version on the left and the new one on the right.. The tool returns a side-by-side diff with added, removed and changed lines highlighted., giving you a precise list of every edit between the two versions. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 4: Verifying a file against its older copy
The task: Verifying a file against its older copy. You start from two code samples - the old version on the left and the new one on the right.. The tool returns a side-by-side diff with added, removed and changed lines highlighted., giving you a precise list of every edit between the two versions. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
Example 5: Reviewing pasted snippets before merging
The task: Reviewing pasted snippets before merging. You start from two code samples - the old version on the left and the new one on the right.. The tool returns a side-by-side diff with added, removed and changed lines highlighted., giving you a precise list of every edit between the two versions. you can edit rather than a blank page.
Make it yours: add one detail the tool cannot know - a real number, a name, a constraint - then read the result once end to end before you keep it.
A Full Worked Example
Input: left: const port = 3000 - right: const port = 8080
Line 12 marked as changed from 3000 to 8080, with added lines in green and removed lines in red.
The pattern behind every example above: context and constraints go in, structure comes out, and your edit makes it true.
How to Build Your Own Examples
- Take a task already on your calendar for this week.
- Write the brief in two sentences: the job and the audience.
- Generate, compare against the version you would have written manually.
- Save the prompt alongside the result so the second run takes seconds.
Getting More From Each Example
Most people stop at the first result. Generate a second version with one changed variable - length, tone or angle - and compare. The better version usually appears on the second run, not the first.
Frequently Asked Questions
Does it understand programming languages?
It compares text line by line, so no language knowledge is needed and any file type can be compared.
Can I compare more than two samples?
Compare two at a time and repeat for additional versions to keep the panels readable.
Will it merge the changes for me?
No - it shows differences, and you apply the highlighted edits to your own copy.
Is my code stored?
No - comparison happens in your browser and nothing is retained.
