Key takeaways
- Brandlight is the enterprise heavyweight: strong source attribution and sentiment analysis, but quote-only pricing and a sales-led pilot model that most agencies can't resell to mid-market clients.
- Search Party, the AI visibility startup many agencies shortlisted in 2025, appears to have gone dark. Its original domain is parked for sale, and the searchparty.com site now belongs to an unrelated AI automation consultancy. Treat any 2025-era comparison article still listing it as a live option with suspicion.
- AthenaHQ is the accessible middle option: published pricing (free Essential plan, paid tiers from roughly $95 to $295/month), an Action Center that turns data into tasks, and a partner program that refers leads to agencies.
- None of the three gives you the full monitor-plus-execute loop at agency-friendly pricing. If you want tracking, crawler logs, and automated content production under one roof with white-label client portals, Promptwatch is worth a look before you sign anything.

Brandlight: the enterprise option agencies can admire but rarely resell
Brandlight came out of stealth in April 2025 and quickly landed names most platforms spend years chasing: Estée Lauder, LG, Kimberly-Clark. That pace says something about the product, and also about how hungry enterprise CMOs were for exactly what it sells.
What Brandlight does differently from most AI visibility tools is source attribution. Instead of just telling you that ChatGPT mentioned your client 14 times this week, it traces each answer back to the publishers shaping it. Which review site, which editorial piece, which Reddit thread fed the model's opinion. For an agency running earned media or digital PR alongside AI visibility, that mapping is genuinely valuable. It turns "we should do some outreach" into an actual target list.
The platform also runs the full loop: visibility measurement, sentiment scoring, content generation through a multi-agent workflow (strategist, writer, editor, validator), and partnership recommendations. Brandlight's own research claims roughly 85% of the sources AI cites for category questions are third-party or social rather than the brand's own domain, which is why that publisher-level lens matters so much.
Where it falls short for agencies
The problems are structural, not quality problems:
- No public pricing. Every deal starts with a demo and a paid 3-month pilot. You cannot markup or bundle what you can't price.
- Enterprise-only positioning. If your client roster is mid-market SaaS and DTC brands, the sales process will be heavier than the engagement.
- Fewest engines tracked among serious competitors, per Profound's agency comparison, and the shortest track record on the market.
Brandlight is the right answer when a Fortune 500 client wants to change what AI says about them, not just measure it. For an agency with twelve retainer clients at $3k a month, it's the wrong tool, full stop.
Search Party: a cautionary tale every agency should read
Search Party
Here's the part most comparison articles won't tell you, because most were written in 2025 and never updated.
Search Party, the AI visibility platform that appeared on several "best AI visibility tools" lists, appears to be gone. The searchparty.ai domain is now parked for sale. The searchparty.com domain belongs to a different business entirely, an AI automation consultancy called Joymore that engineers custom workflows. Same name, unrelated product.
I'm not writing this to dunk on a startup. The AI visibility market is barely two years old, vendors are pre-seed to seed stage, and consolidation was always coming. But it should change how agencies buy.
If you built your client reporting on a platform that vanishes, you lose the historical data, the dashboards, and the credibility. So before you commit to any vendor in this space, young ones especially, ask three questions:
- How is the company funded, and what happens to my data if you shut down?
- Can I export everything, on a schedule, in a format I actually own?
- Is there a self-hosted or at minimum a full API fallback for my reporting?
Any vendor that bristles at those questions is telling you something.
AthenaHQ: the pragmatic mid-market pick
AthenaHQ is what I'd point a growing agency toward among these three. It tracks visibility across eight engines (ChatGPT, Perplexity, Claude, Gemini, Grok, Copilot, Meta AI, DeepSeek, and Google AI Overviews), monitors competitor visibility, and pushes fixes through an Action Center that converts tracking data into prescriptive next steps rather than a wall of charts.
The pricing is public, which already puts it ahead of Brandlight for agency planning: a free Essential plan to test, paid tiers starting around $95/month, with Starter plans listed at $295/month and enterprise custom. Integrations cover the reporting stack agencies actually use: GA4, Search Console, Looker Studio, Tableau, Power BI, Shopify, and Webflow.
The agency angle is AthenaHQ's most distinctive feature. Its partner program refers qualified inbound leads to agencies based on focus areas and offers discounted client licenses, alongside client workspaces and pitch environments. If your agency's growth model runs on referrals, that's a real draw, not a gimmick.
Where it falls short
Two honest caveats from third-party reviews:
- Prompt volume estimates come from a proprietary machine learning model the company doesn't fully disclose, and tracking is metered on credits tied to your plan. You're trusting a black box for part of your demand data.
- Its AI-generated content reportedly needs heavy editing before it's client-ready, so it's a monitoring platform with content assistance, not a production engine.
AthenaHQ is a capable monitor with a strong lead program. It is not yet the full execution stack.
What agencies should actually demand from an AI visibility platform
The three platforms above, and frankly most of the market, cluster around monitoring. But the agencies winning AI search retainers right now are doing three things: walking into pitches with the prospect's real AI data on screen, producing the content that closes the gap, and showing the client what that content returned in traffic and conversions.
That last mile matters more than people expected. AI answers are volatile in ways rank tracking never prepared us for. Promptwatch's data shows, for instance, that Reddit's share of ChatGPT Search citations collapsed from roughly 4% to 0.5% in a single day in August 2026, and that ChatGPT started using the site: operator at scale overnight, nearly doubling searches per response. A platform that only snapshots mentions weekly will miss shifts like these entirely.
So when you're evaluating any vendor, including the three above, check for:
-
Crawler logs. Knowing when ChatGPTBot or ClaudeBot actually hit your client's site, what they read, and whether they hit errors. This explains the "why" behind a visibility score. Most competitors don't have it at all.
-
Real UI data, not just API calls. User-facing answers, citations, and shopping recommendations can differ from what APIs return.
-
Traffic attribution, not just mentions. A mention that never sends a visitor is a vanity metric. Tie AI visibility to actual sessions and conversions.
-
Content execution. Gap analysis is table stakes. The question is whether the platform can plan, write, and publish the fix, or whether that work lands back on your team's plate at agency margins.
-
White-label reporting. If the client sees the vendor's logo, you're introducing them to your replacement.
The option none of these comparisons usually mention
Since this guide exists to help agencies choose, it would be dishonest to leave out the platform that covers the full monitor-to-execution loop at agency pricing. Promptwatch is used by 1,840+ brands and agencies, rates 4.7/5 on G2, and has analyzed more than 4.5 billion citations, clicks, and prompts.
What separates it from the three platforms above is that it doesn't stop at telling you where a client is invisible. Its agents help fix it: content gap analysis, automated GEO-optimized content generation, CMS publishing to Webflow, Framer, or WordPress, and Unified Actions, a prioritized to-do list derived from visibility, citation, and crawler data. It also tracks surfaces most competitors ignore, including Reddit and YouTube citations, ChatGPT shopping recommendations, and sponsored placements in AI answers.
For agencies specifically, the agency plans ($199 to $799/month) include unlimited projects and prompts, 10 seats, and a white-label dashboard with a client portal. That's the difference between reselling a tool and building a practice on it. Agencies like Monks and WPP already run client work this way, using visibility scores and answer gap reports to build content roadmaps.
It's not perfect for everyone. If your client is a Fortune 500 CPG conglomerate that needs deterministic legal guardrails and a forward-deployed engineering team, Brandlight's enterprise posture is built for that procurement process in a way smaller platforms aren't. Match the tool to the client, not the other way around.
How to choose, by agency type
| Your situation | Best fit | Why |
|---|---|---|
| Enterprise or multi-brand holding company clients | Brandlight | Source attribution, sentiment, SOC 2 posture, executed activation with a strategy team |
| Mid-market retainer clients, referral-driven growth | AthenaHQ | Public pricing, Action Center, partner program with inbound leads |
| Scaling AI visibility as a productized service across many clients | Promptwatch | Unlimited projects, white-label portal, automated content production, crawler logs |
| Any client, any vendor | Due diligence checklist | The Search Party situation can happen again. Export rights and funding questions first. |

The bottom line
Brandlight, AthenaHQ, and Promptwatch are all real, funded, operating platforms in 2026. Search Party is a reminder that not everything on a 2025 comparison list still exists. Buy accordingly: verify the vendor is alive, insist on data export, and pick the platform that closes the loop from insight to published content rather than the one with the prettiest visibility score. The agencies that treat AI visibility as a service they deliver, rather than a dashboard they resell, are the ones keeping these retainers past year one.
