Product design feedback

Score a product design UI across six dimensions, then share your scores as a link or export them as JSON for an LLM.

Overall score

0.0/10

0 = not executed · 10 = perfect

Share as JSON

Updates as you score. Copy it to hand an LLM.

How to use this rubric

Score a product design below, then put the rubric to work giving an LLM an objective bar to hit. Here's the flow we follow at Good Measure.

1. Score the work

Drag each slider to rate the work against the criteria. Hover the info icons to see what each one means, and add notes per section as you go. Your overall score and a shareable link update live.

2. Make it your own

The default criteria are a starting point. Hit Edit rubric to add sections and labels that capture what good actually looks like to you. A rubric is most useful when it encodes your taste and experience, not generic advice.

3. Prime the LLM

Before the model starts, hand it the rubric so it knows the bar. Hit Copy JSON, then prompt it with something like this:

My goal is to [describe the task].

Evaluate your output against this rubric:
[paste the JSON]

Target an average score of 8.5+ across all criteria.

Ask me questions until you have enough context, then begin.

4. Score and iterate

When the output comes back, score it here, copy the JSON again, and ask for a revision:

Revise your output to reach the target scores.

Here's how I scored the latest version:
[paste the JSON]

Target an average score of 8.5+ across all criteria.

Two or three rounds usually gets there. If it keeps missing, that's a sign the rubric itself needs sharpening.

Let an agent drive

This tool speaks WebMCP, so an in-browser AI agent can read the rubric and fill in the scores itself — no copy-paste required.
