AI Output Comparison Report Builder

Compare up to three AI responses to the same task. Use the same rubric for each output, capture evidence, and export a report you can inspect in a spreadsheet. The tool does not decide which answer is true; you must verify claims against reliable sources.

1. Define the comparison

Task or prompt used for all outputs *

Task-specific requirements

Reference material / verification basis

2. Add outputs

Use neutral labels such as Output A, Output B, and Output C when you want to reduce brand bias. The tool processes these fields locally in your browser.

Output A label

Output A response *

Output B label

Output B response *

Output C label (optional)

Output C response (optional)

3. Score each output

Score from 0 (poor/not met) to 5 (excellent/fully met). Default weights total 100%. Use evidence notes to explain why you assigned each score.

Criterion	Weight %	Output A (0–5)	Output B (0–5)	Output C (0–5)

Enter at least two responses, then calculate.

Output A— / 100

Output B— / 100

Output C— / 100

Fair-comparison checklist

Use the same prompt, context, reference documents, and output requirements for each model.
Record model names, versions, run dates, and settings separately when known; never guess missing metadata.
Use neutral labels during scoring if possible, and verify factual claims against the same sources.
Report the rubric, weights, limitations, and missing information alongside any conclusion.
