Agentcy, the PR-Ops platform for comms teams, is open-sourcing the AI visibility module of its platform, making it free for anyone to download and use. The move gives PR and communications agencies an auditable foundation for tracking not just how brands appear in AI search results, but whether what those results say about them is actually correct. The module has been built with the industry and for the industry, developed with input from senior practitioners across PR, corporate communications, and public affairs.
For PR teams, presence is no longer enough. What the AI says about you matters as much as whether it mentions you at all. A brand can appear frequently in AI responses and still be systematically misrepresented. It can be cited as a source without ever being named in the answer. Source presence and narrative presence are different problems, and most tools only solve one of them.
Agentcy defines accuracy precisely: the extent to which AI search results describe a brand correctly, measured claim by claim against a verified source of truth. The platform breaks each brand description into discrete, testable claims, checks them against approved brand material, and flags every divergence: wrong facts, outdated positioning, missing context, competitive misattribution. Every score is traceable back to the raw prompt, the raw answer, the cited URLs, and a timestamp. Nothing is a black box.
The open source module of Agentcy covers:
- How often a brand is mentioned or recommended across leading AI models
- Whether those mentions are factually accurate and correctly positioned, validated against a brand source of truth
- Which sources are cited in AI-generated responses, and whether citations actually translate into brand mentions
- Whether mentions are positive, neutral, or negative in tone
- How competitors are positioned in the same responses
- How visibility, accuracy, and positioning shift over time
The standard market bundle is visibility tracking, citation analysis, sentiment, competitor benchmarking, and historical trend monitoring. Those are now table stakes. What is missing is an accuracy layer: a way to validate whether what AI says about your brand is factually correct. Sentiment is not accuracy. Source tracking is not accuracy. A cited domain is not proof that the answer is right.
"Much of the hype about GEO centres on visibility but for the work we do with clients in the corporate, government and not-for-profit space then being portrayed accurately in AI answers is even more important. Tools that just focus on visibility can't provide corporate communications professionals with the data they need to protect and improve reputations," said Stuart Bruce, The PR Futurist and Co-CEO of AI communications transformation consultancy Purposeful Relations.
Expensive tools. Inconsistent results. Agencies are pushing back.
A recent Digiday investigation found marketers are questioning expensive AI visibility tools after inconsistent results and a limited ability to prevent the hallucinations and misattributions they were bought to address. Digiday, 1 May 2026. By making the measurement layer open-source, Agentcy is giving agencies a foundation they can inspect, verify, and run themselves. Not a proprietary score, but a transparent, reproducible method they can stand behind with clients.
"Visibility tells you whether you're in the room. Accuracy tells you whether what's being said is true."
"The market is telling us something," said Tom Fry, CTO at Agentcy. "Agencies are paying for tools that measure whether a brand appears in a result. Not whether what it says is correct. That is the gap we built this to address. Flying blind is expensive. Open-sourcing the measurement layer means any agency can verify the results themselves, without trusting a black box they did not build and cannot inspect. If PR is going to be taken seriously as a performance discipline, accuracy has to be part of what we measure."
Released under the MIT licence, the platform runs locally in minutes or can be hosted on an agency's own infrastructure. Full documentation and setup instructions are included.
The platform is available now at github.com/AgentcyPR/ai-visibility.
