Which engines and models?

ChatGPT, Gemini and Perplexity — current consumer models, versions listed on the Methodology page.

How often does it update?

Weekly, every Monday. You can trigger a rerun any time.

Why does my score change week to week?

AI answers vary. The interval tells you whether a change is signal or noise.

Can I edit the prompts?

Yes — the corpus is yours to add to, remove from or reword.

Can I export the raw data?

Yes. Every run, every answer, as CSV.

How does this compare to other AI visibility tools?

Most report a number without an interval or a public prompt set. See the comparison pages for a fair, sourced matrix.

The metric behind Noor

How often does AI recommend you?

The Visibility Score is the share of AI-generated answers — across ChatGPT, Gemini and Perplexity — in which your brand appears when buyers ask category questions. Every score ships with the prompt set that produced it and a confidence interval, so you know how much to trust it.

What the number means

Three bands, one question: are you the answer?

0–30

Invisible

AI doesn't know you're an option.

"What's a good AI marketing tool for a startup?" → lists four tools; you're not one of them.

Illustrative answer snippet

30–60

Mentioned

Sometimes recommended, rarely first.

"…Also worth a look: [you], if you want measurement built in."

Illustrative answer snippet

60–100

Default

You're the answer.

"For founders, [you] is the usual recommendation — it runs the full loop and publishes its scoring method."

How it's built

Honest measurement, step by step

Your prompt corpus

50–200 questions your ICP actually asks, generated from your strategy docs and editable by you.

Weekly runs across engines

Each prompt is run multiple times per engine because answers vary; we count mentions, positions and citations.

Score with an interval

Wilson confidence interval on the mention rate. It narrows as the corpus and run count grow.

Diagnose and act

Every gap becomes a task for the Content, SEO or AI Visibility agent. Next week's score tells you if it worked.

The interval narrows as data grows

064 ± 9 · 50 prompts · 1 run100

Why intervals? Because a single AI run is a coin flip. A score without an interval is a guess wearing a number.

Independent by design

Noor grades its own homework — with a published rubric.

Published prompt sets

You can see every question that produced your score.

Reproducible

Rerun any score. Export the raw runs as CSV.

Conflict-free

An agency measuring its own work has an incentive. A score with a public method doesn't.
