The method behind every comparison

How Prism Discovery compares

Quick answer: Every Prism Discovery comparison page asks the same six questions of both products, Prism Discovery included: what the competitor does, whether Prism does it, where the competitor stops, what Prism adds, which covers more of the workflow, and what is left for the user to do.

Which six questions does every comparison ask?

The pattern is not one product versus another. It is: the competitor does X, and Prism Discovery does X plus Y. Six questions produce that shape on every row, and the two that carry the argument are the third and the fourth: where the competitor stops, and how far Prism Discovery takes the same capability.

1 of 6
Competitor capability.What does the competitor do?
2 of 6
Prism equivalent.Does Prism Discovery do the same thing?
3 of 6
Competitor boundary.Where does the competitor’s capability stop, as their own public pages describe it?
4 of 6
Prism extension.What does Prism Discovery add beyond that boundary?
5 of 6
Workflow coverage.Which product covers more of the relevant workflow?
6 of 6
User impact.What additional work, tooling or friction remains for the user?

Where does value sit in AI visibility tools?

Value in this sector moves from dashboards to action to autonomy. The ladder below has four rungs, and the top rung is published empty on purpose: nobody, Prism Discovery included, ties AI visibility to revenue today, and saying so is what makes the ladder a method rather than a pitch.

Tier 4, Attribute.Ties it to revenue.Nobody, including Prism Discovery.
Tier 3, Learn.Measures whether it worked and changes what it makes next.Prism Discovery.
Tier 2, Act.Turns the finding into content and ships it.Frase.
Tier 1, Report.Tells you where you stand.Otterly.AI, Peec AI, Profound.

How does Prism Discovery score on its own rubric?

The six rows below open every comparison page on this site. Here they are applied to Prism Discovery alone, with the boundary column filled in as plainly as it is for anyone else, so a reader can hold Prism to the same standard the pages hold everyone else to.

Capability	What Prism Discovery does	Where Prism Discovery stops
Measures per engine, or one blended number	Prism Discovery measures per engine: a Prism Visibility Index for each engine, weighted for brand mention, source authority and answer position.	Prism Discovery measures five engines, ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews, and no others today.
A finding becomes a tracked object with a lifecycle	Prism Discovery records each finding as a typed Opportunity with a status, re-checked 14 days after it is resolved.	Prism Discovery detects findings from Search Console data; AI visibility scores do not yet raise a finding, so the loop runs from publish to visibility and not the other way.
Can it refuse to publish its own output	Prism Discovery blocks a reviewed draft that fails the expert panel from approval and publishing, and records every override.	A draft that was never reviewed does not block in Prism Discovery.
Does it measure whether what you published worked	Prism Discovery measures AI visibility when content changes and again 14 days later, storing the difference against that change.	Prism Discovery measures visibility, not revenue.
Does what it learns change what it generates next	Prism Discovery, on Pro and Enterprise, lets measured outcomes steer how the next draft is written and scored.	Prism Discovery Starter and the trial generate without the learning loop, and the loop needs enough measured outcomes before it says anything.
Governed by construction, or by policy page	Prism Discovery is governed by construction: a public AEO ontology, with AI disclosure and audit records built in.	Prism Discovery’s disclosure and audit records cover content produced through Prism Discovery.

Where does the rubric stop for Prism Discovery?

A comparison page is only worth quoting if the product it favours is held to the same line. Two facts sit outside every row above and belong on the record, so that no comparison page can imply otherwise.

No revenue attribution. Tier 4 of the ladder is empty for every product on it, Prism Discovery included.
The cheapest plan is £89 a month and the 14-day trial costs £16.66.

How are competitor claims written and checked?

A competitor boundary is written as a sourced absence: their public pages do not describe the capability, checked on a stated date. It is never written as an inability, because the UK CAP Code and EU Directive 2006/114/EC require a comparative claim to be verifiable, and what a public page does not say is verifiable where a claim about a company’s internals is not. Competitor sources are cited as text and not linked, and every Prism Discovery claim is kept with a record of the evidence it was verified against and the date.

What is frequently asked about how we compare?

The questions below are the ones readers of the comparison pages ask about the method itself, rather than about any one product.

Why do the comparison pages not list where a competitor is better?

Because the pages exist to show what Prism Discovery does and how far it goes, and the constraint on them is accuracy rather than balance. Every competitor statement is a dated account of what that company’s own public pages do or do not describe. Where they describe something Prism Discovery does not do, the page says so in the row that covers it.

How is a competitor boundary written?

As a sourced absence, never as an inability. A row says that a capability is not described on the competitor’s public pages, with the date those pages were checked, and never says the competitor cannot do it. The UK CAP Code and EU Directive 2006/114/EC require comparative claims to be verifiable, and an absence from a public page is verifiable in a way a claim about their internals is not.

How often are the comparison pages re-verified?

Quarterly at least, and whenever a competitor changes its pricing or a Prism Discovery claim changes in the product. Each page shows the date its competitor claims were checked and the date its Prism Discovery claims were verified, and every row is kept with a record of the evidence behind it.

The same six questions are applied on every page below, so the rows line up across products and the rubric page explains how each one was answered.
