Comparison: two ways to do one thing, side by side, same task, same clock

The split-screen comparison that is fair enough to be believed: identical task, identical start, a visible timer, a verdict earned on screen. Prompt returns the script and the fairness checks.

Write a side-by-side comparison script: {option A} vs {option B} for {task}. The format works when the viewer believes it was fair, so the fairness is part of the script. Use this format when one option replaces something slower or more expensive; use a generic name for the other option ('the usual way', 'a desktop editor'), never a competitor's brand.

Structure (40 s, 9:16 split top/bottom, or 16:9 split left/right):
- 0-3 s: the question, spoken and on screen: '{A} or {B} for {task}?' Both halves show the starting state, identical.
- 3-6 s: the rules, on screen as a 3-line list: same file / same start / timer on both. Spoken: 'Same photo, same start, clock running.'
- 6-30 s: the task, both halves running at once. A timer in each half. Spoken lines only when one side reaches a step: 'A is done cutting out. B is still selecting.' Max 6 lines, max 12 words each.
- 30-36 s: results side by side, timers frozen. Spoken: the two times and one difference you can see.
- 36-40 s: verdict in one sentence, with the case where the loser is still the right choice (one clause). No download ask; the result is the argument. Comment ask: 'what would you compare next?'

Word budget: 80-90 words at 165 wpm. On-screen: the question, the rules list, two timers, the two final times, the verdict in 5 words.

Return: the fairness checklist (what must be identical), then a table (time, left/top half, right/bottom half, spoken line, on-screen text).

Option A: {option A}
Option B: {option B}
Task: {task}
What I expect to find: {honest guess, including where B wins}

In Claude Code, paste the prompt as a message.

Example

A: a background-removal photo app on a phone. B: the usual way, a desktop editor with a selection tool. Task: three product photos on white.

Fairness checklist: same three photos sent to both devices, both start from the file open, timers start on the first tap or click, no pre-made selections, both exported at the same size.

Time Top (phone app) Bottom (desktop) Spoken On-screen
0-3 s Photo 1 open Photo 1 open Phone app or desktop editor for three listing photos? PHONE vs DESKTOP
3-6 s Finger hovering Cursor hovering Same photos, same start, clocks running. SAME FILES · SAME START · TIMER
6-12 s Tap, background drops Selection tool tracing the handle Phone’s done with one. Desktop is still on the handle. 0:06 / 0:06
12-20 s Photo 2, 3 done Still refining the edge of photo 1 Two and three. Desktop, edge of number one. 0:20 / 0:20
20-30 s Export, done, timer stops Photo 2 selection Phone stops at thirty-one seconds. 0:31 / 0:30
30-36 s Three results Three results, timer stopped later Thirty-one seconds against four minutes ten. Look at the handle edge: the desktop one is cleaner. 0:31 vs 4:10
36-40 s Phone for a listing. Desktop when the edge is the product. What should I compare next? PHONE FOR LISTINGS

Tips

  • Name the case where the loser wins. A comparison with no concession reads as an ad and gets argued with instead of shared.
  • Run the slower side for real and speed up the footage with a visible label. Cutting it short makes the result a claim instead of a measurement.
