First, who made this map
Known & Cited is one person: me, Russ Read-Barrow. I'm a GEO and AI search consultant for PR and comms people, with twenty years in international PR, agency-side. I'm on this page too, so here's exactly what I do and how I'm different, before you read about anyone else.
- A person, not a platform. You talk to me and I do the work. No dashboard to log into, no junior, no long contract.
- Tool-agnostic. I don't sell a platform and I'm not tied to one. I use whichever tools suit the brief, sometimes ones on this page, and I always tell you which ones I used and why.
- No scores. AI answers change too much from run to run for a single number to mean much. I'll show you who's being cited, how often, and why.
- Built for PR and comms. The three things comms teams actually need: your share of voice in AI answers against competitors, who the sources are and why, and the types of content shaping the answers. All of it feeds your content and media relations plans.
- Tailored and priced per brief. Anything from a team briefing to practical guidance to a proper multi-market study. You get a written scope and a fixed price before anything starts.
My whole method is on my approach page. I'm not the right fit if you want a daily dashboard or an agency to produce lots of content. In that case, some of the options below will suit you better, and I'm happy to say so.
Who else is on this page, and who isn't
This page includes tools, platforms and agencies that are active in the UK and are open about what they do and how they do it. That means they publish something meaningful about their method: what they measure, which AI tools they cover, what you get, or how their work runs.
Plenty of agencies now say they "do GEO" with nothing underneath: no method, no description of the work, just the word on a services page. They're not included. That isn't a judgement on the people involved. It's that if you can't see how something works, you can't compare it, and neither can I.
Some more ground rules:
- It's a map, not a ranking. Nobody paid to be here, and nobody is scored.
- It's built from what each company publishes, plus trade press. I haven't used every product listed.
- Where something important isn't published, such as which AI tools a platform covers, I say so.
- It's UK-focused because that's the market I know well enough to describe properly.
- Things change fast. If you're listed and something here is out of date, tell me and I'll fix it.
The backdrop: AMEC draws a line
In May 2026, AMEC, the global body for communications measurement, launched its GEO Principles and a practitioner's guide. A companion piece warned that "AI visibility alone is the next AVE", the vanity metric PR spent two decades trying to kill. The point: a single opaque number, cut off from outcomes, isn't a strategy.[1]
That shifts the question buyers should ask. Not "who can give us an AI visibility number?" but "who can tell us what's really going on, show us how they know, and help us act on it?"
How to read the field
Two questions sort almost everyone:
- Are you buying a tool or a person? A dashboard you log into and act on yourself, or people who interpret it and advise. Some do both.
- What's the scope? Measurement only, measurement plus advice, or measurement, advice and doing the work (content, PR, technical fixes).
Neither answer is better. A team with analysts and writers in-house might want a tool. A team that needs to explain AI to a board might want a person. The mistake is buying one when you need the other.

PR platform · Generative Pulse
Muck Rack
Generative Pulse launched in July 2025 inside Muck Rack, tracking which outlets and journalists AI tools cite in a given category, which is very relevant to media relations. That in-platform tool is now called Muck Rack AI Visibility. Since 26 October 2026, Generative Pulse is also a standalone platform in early access, open without a Muck Rack subscription, with a full launch planned for early 2027. It covers ChatGPT, Gemini, Claude, Perplexity and Google AI Overviews and scores brands on four "SEEN" signals: share of answer, evaluation, error-rate accuracy and narrative alignment. Muck Rack also publishes the What Is AI Reading? research.
- What you get
- Software: inside Muck Rack, or standalone through Generative Pulse.
- How open
- Names the AI tools covered and publishes research; its October report describes a 1,020-prompt test. How the SEEN scores are calculated, and the sample sizes and question design behind them, aren't published. It's a scoring framework, so the questions below apply.
- Suits
- Muck Rack users focused on media relations, and teams who want a dedicated AI view without the full suite.

- How open

- Suits
- PR teams who want a PR-shaped tool.
Agency tool · GEOView

Launched a GEO Planning Unit and its GEOView tool in May 2026. GEOView runs hundreds of questions across AI tools and repeats each one, because answers vary from run to run, then maps what AI says about a brand against what the brand wants to be known for. The unit is led by a named Head of GEO.
- What you get
- A diagnostic report and action plan, plus agency services.
- How open
- Method described in launch coverage, including repeat runs.
- Suits

What's changing
- PR platforms have built it in. Muck Rack, Meltwater, Onclusive and Cision all added AI visibility features between mid-2025 and mid-2026. For many PR teams, the first look at AI visibility will now come from a tool they already have.
- The standards body wants rigour. AMEC's principles push away from single scores and towards measurement linked to outcomes.
- Earned media keeps proving its role. Study after study finds most AI citations point to third-party sources. That's pulling GEO towards PR and away from pure SEO.
- Rank tracking looks shaky. With AI answers rarely repeating, tools that report a precise "position" in AI deserve hard questions.
- Measuring AI is getting harder. Gemini quietly stopped adding tracking tags to the links it cites at the end of September 2026, so visits from its app can show up as "direct" traffic in your analytics. Marketers spotted it; Google hasn't commented. Expect more changes like this, and treat AI traffic figures as a floor, not a total.
- "GEO" pages are everywhere. Lots of agencies have added the label. Far fewer explain what they actually do. Hence the rule for this page.
Questions to ask anyone, including me
- Who does the work? A named person, or a platform?
- What exactly is measured? Which AI tools, which questions, how many runs, which markets and languages? Is it written down?
- How sure are you? Does the number come with a sense of how much it moves between runs?
- What will I be able to do differently afterwards? And who does it: you, me, or someone else?
My answers: me; whatever the brief needs, written down before we start; I'll always tell you how much a finding moves and how far to trust it; and you'll get clear recommendations, with help acting on them if you want it.
