Key takeaways
- Most AI visibility platforms are monitoring-only dashboards -- they show you where you're invisible but don't help you fix it.
- Promptwatch is the only platform in this comparison that closes the full loop: gap analysis, AI content generation, and traffic attribution in one place.
- Profound has the deepest analytics at the enterprise tier but costs significantly more and lacks content creation tools.
- Otterly.AI is the most affordable entry point but is missing crawler logs, visitor analytics, and any optimization workflow.
- AthenaHQ is a solid monitoring tool for teams that just want clean dashboards, but it won't help you act on what you find.
The AI search landscape shifted fast. In 2024, "AI visibility" was a niche concern for forward-thinking SEO teams. By 2026, it's a core marketing KPI -- Booking.com, major retailers, and B2B SaaS companies are all tracking how often ChatGPT, Perplexity, and Google AI Overviews recommend them.
The problem is that the tool category exploded alongside the demand. There are now 28+ platforms claiming to solve AI visibility, and most of them look nearly identical on a features page. This guide cuts through that.
I compared four of the most-discussed platforms -- Promptwatch, Profound, Otterly.AI, and AthenaHQ -- across the dimensions that actually matter for marketing teams: what they monitor, what they help you do about it, how they handle content, and what they cost.
What marketing teams actually need from an AI visibility tool
Before getting into the platforms, it's worth being clear about what "AI visibility" work looks like in practice for a marketing team.
You're not just asking "does ChatGPT mention us?" You're asking:
- Which prompts are driving traffic to competitors but not us?
- What content do we need to create to start appearing in those answers?
- Which AI models are citing our pages, and which are ignoring us?
- Is our new content actually improving our visibility scores over time?
- Can we connect AI citations to real website traffic and revenue?
That's a full workflow, not a dashboard. And most tools only cover the first question.

Promptwatch: the only platform built around taking action
Promptwatch is the platform I'd recommend to most marketing teams, and the reason comes down to one thing: it's the only tool here that doesn't stop at showing you data.
The core workflow is a loop. First, Answer Gap Analysis shows you exactly which prompts competitors are appearing for that you're not. Not vague category-level gaps -- specific questions and topics that AI models want to answer but can't find on your site. Second, a built-in AI writing agent generates articles, listicles, and comparisons grounded in 880M+ real citations, prompt volumes, and competitor analysis. Third, page-level tracking shows whether your new content is actually getting cited, by which models, and how often. And a traffic attribution layer (GSC integration, code snippet, or server log analysis) connects those citations to actual revenue.
That loop -- find gaps, generate content, track results -- is what separates Promptwatch from every other tool in this comparison.
Beyond the core loop, Promptwatch has features that competitors simply don't have. AI Crawler Logs show you in real time which pages ChatGPT, Claude, and Perplexity are crawling, how often they return, and what errors they encounter. Reddit and YouTube tracking surfaces discussions that directly influence AI recommendations. ChatGPT Shopping tracking monitors product recommendation carousels. Query fan-outs show how one prompt branches into sub-queries, which is genuinely useful for content planning.
It monitors 10 AI models: ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, Copilot, Mistral, Meta AI, and Google AI Overviews. That's the broadest coverage in this comparison.
Pricing starts at $99/mo for the Essential plan (1 site, 50 prompts, 5 articles). Professional is $249/mo (2 sites, 150 prompts, 15 articles, crawler logs). Business is $579/mo (5 sites, 350 prompts, 30 articles). Agency and enterprise pricing is custom.
The one honest caveat: if you genuinely only need a monitoring dashboard and have no interest in content creation or optimization, Promptwatch has more features than you'll use. But for any team that wants to actually improve their AI visibility -- not just measure it -- it's the right choice.
Profound: the enterprise analytics leader
Profound is the most analytically deep platform in this comparison. Its Answer Engine Insights are detailed, its prompt volume data is reliable, and its coverage across AI models is strong at the Growth tier and above. If you're a large enterprise team that needs to report on AI visibility to leadership and wants robust data to back it up, Profound is a serious option.
The agency mode is worth noting -- it includes brand configurations and pitch environments that make it easier to manage multiple clients and present findings. For agencies with enterprise clients who care more about reporting than optimization, that's genuinely useful.
But Profound has two real limitations. First, it's expensive. One independent review found it priced about 48% above the market average, with key features locked behind enterprise tiers. Second, it's monitoring-only. Profound shows you where you're invisible in AI search, but it doesn't help you create the content to fix it. There's no built-in content generation, no answer gap analysis that feeds into a content workflow, and no traffic attribution layer.
If your team has a separate content operation and just needs the best possible visibility data to feed into it, Profound is worth evaluating. If you need the full workflow in one platform, it falls short.
Profound
Otterly.AI: the affordable entry point
Otterly.AI is the most accessible platform in this group. It's priced for teams that are just starting to think about AI visibility and want to monitor brand mentions across ChatGPT, Perplexity, and Google AI Overviews without a significant budget commitment.
For what it does, it works. You can set up prompt monitoring, track brand mentions, and get a basic sense of your share of voice across a handful of AI models. The interface is clean and the setup is fast.
The limitations are significant, though. There are no crawler logs, no visitor analytics, no content generation tools, and no answer gap analysis. Otterly.AI shows you data but provides no path to acting on it. It also covers fewer AI models than Promptwatch or Profound, which matters as the AI search landscape continues to fragment across different engines.
For a small team or solo marketer who wants to dip their toes into AI visibility tracking without spending much, Otterly.AI is a reasonable starting point. For any team that wants to actually improve their visibility, they'll quickly outgrow it.
Otterly.AI
AthenaHQ: clean monitoring, limited optimization
AthenaHQ sits between Otterly.AI and Profound in terms of depth. It has solid monitoring capabilities, decent competitor heatmaps, and a clean interface that's easy to navigate. Teams that want to understand their AI visibility position relative to competitors will find it useful.
Like Profound and Otterly.AI, though, AthenaHQ is monitoring-focused. It doesn't have content generation, answer gap analysis that feeds into a workflow, or traffic attribution. You can see where you're losing to competitors in AI search, but the tool doesn't help you do anything about it.
It's a reasonable choice for teams that already have strong content operations and just need visibility data to inform them. For teams that want an end-to-end platform, it's not the right fit.
How the platforms compare on specific use cases
For teams that want to improve AI visibility, not just measure it
Promptwatch is the clear choice. The Answer Gap Analysis + AI writing agent + tracking loop is the only workflow in this comparison that takes you from "we're invisible for this prompt" to "we published content and our citation rate improved." No other platform here does that.
For enterprise reporting and analytics depth
Profound has the edge on pure analytics. If your primary need is detailed, trustworthy data to present to a CMO or board, and you have a separate content team to act on it, Profound's data depth is hard to match at the enterprise tier.
For budget-conscious teams just starting out
Otterly.AI gets you monitoring for less. But be realistic about what you're getting -- it's a starting point, not a growth tool.
For agencies managing multiple clients
Promptwatch's agency and enterprise pricing supports multi-site management, and the content generation features mean you can actually deliver optimization work, not just reports. Profound's agency mode is also worth a look if your clients care primarily about data and reporting.
For tracking AI crawler behavior
Only Promptwatch has AI Crawler Logs. If you want to understand how ChatGPT and Perplexity are actually crawling your site -- which pages they read, how often they return, what errors they hit -- no other platform in this comparison offers that.
What the research says
A 2026 comparison of 12 GEO platforms rated Promptwatch as the only "Leader" across all categories. Profound and AthenaHQ scored well on monitoring depth but were rated lower on optimization and action-taking capabilities. Otterly.AI was noted as a solid entry-level option but missing multiple core features.
One independent review that tested five Profound alternatives over 21 days found that Promptwatch offered the broadest LLM coverage combined with traffic attribution -- a combination no other platform matched. The same review noted Profound's 48% price premium over market average as a consistent reason customers look for alternatives.
Zapier's 2026 roundup of AI visibility tools positioned Profound for "all-in-one enterprise needs" and Otterly.AI for "affordability" -- which roughly aligns with how I'd characterize them. Neither review, however, fully captured the content generation gap that separates Promptwatch from the rest.
Pricing comparison
| Platform | Entry plan | Mid tier | Enterprise |
|---|---|---|---|
| Promptwatch | $99/mo (1 site, 50 prompts) | $249/mo (2 sites, 150 prompts) | Custom |
| Profound | ~$149/mo | ~$399/mo | Custom |
| Otterly.AI | ~$49/mo | ~$99/mo | Custom |
| AthenaHQ | ~$99/mo | ~$249/mo | Custom |
Promptwatch's pricing is competitive given what's included. The Essential plan at $99/mo includes content generation (5 articles/mo), which no other entry-level plan in this comparison offers at all.
Bottom line
If you're a marketing team that wants to understand and improve your AI search visibility, the honest answer is that three of these four platforms will leave you with data and no clear path forward. Profound, Otterly.AI, and AthenaHQ are all monitoring tools. They'll tell you where you stand. They won't help you change it.
Promptwatch is different because it's built around the full optimization cycle. The gap analysis feeds into content creation, which feeds into tracking, which feeds into traffic attribution. That's the workflow marketing teams actually need in 2026 -- not another dashboard.
For teams just starting out who want to test the waters cheaply, Otterly.AI is a reasonable first step. For enterprise teams with deep analytics needs and separate content operations, Profound is worth evaluating. But for the majority of marketing teams who want a single platform that helps them actually rank in AI search, Promptwatch is where I'd start.
