Key takeaways
- All four platforms track brand mentions across AI search engines like ChatGPT, Perplexity, and Google AI Overviews — but that's where the similarities end.
- Profound has the deepest analytics and broadest engine coverage, but it's priced 48% above market rate and won't help you create content to fix what it finds.
- Otterly.AI is the easiest entry point for small teams, but it's monitoring-only with limited depth.
- AthenaHQ is monitoring-focused with solid competitor tracking, but lacks content generation and crawler log access.
- Promptwatch is the only platform in this group that closes the full loop: find gaps, generate content to fix them, then track the results.
Why this comparison matters right now
AI search isn't a trend anymore. ChatGPT, Perplexity, Google AI Overviews, and Gemini are now part of how millions of people research products, compare vendors, and make buying decisions. If your brand isn't showing up in those answers, you're losing ground to competitors who are.
The problem is that the tooling market has exploded. There are now dozens of "AI visibility" platforms, and most of them do roughly the same thing: they run prompts through AI engines and tell you whether your brand got mentioned. That's useful, but it's only the first step.
The real question is: after you know you're invisible, what happens next?
That's the lens I'm using to compare these four platforms. Profound, Otterly.AI, AthenaHQ, and Promptwatch are four of the most talked-about options in 2026. They're different enough to matter, and similar enough that the choice isn't obvious. Let's get into it.
What each platform actually does
Before the comparison table, a quick orientation on each tool's positioning:
Profound is the enterprise-grade option. It monitors 10+ AI engines, has deep analytics, and is genuinely impressive on the data side. It's built for larger teams that want comprehensive visibility reporting. The catch: it's expensive, and it doesn't help you act on what it finds.
Profound
Otterly.AI is the lightweight entry-level option. It's fast to set up, covers the main AI engines, and gives you a clean dashboard. Good for teams that are just getting started with AI visibility monitoring and don't need advanced features yet.
Otterly.AI
AthenaHQ sits in the middle ground. It has solid competitor tracking and brand monitoring, and it's aimed at marketing teams that want to understand how AI models perceive their brand relative to competitors. Like Profound, it's primarily a monitoring tool.
Promptwatch is built around what it calls the "action loop": find visibility gaps, generate content to close them, then track whether the content gets cited. It's the only platform here that includes a built-in AI writing agent specifically designed to produce content that gets cited by AI models.
Feature-by-feature comparison
| Feature | Profound | Otterly.AI | AthenaHQ | Promptwatch |
|---|---|---|---|---|
| AI engines monitored | 10+ | ChatGPT, Perplexity, Google AI | ChatGPT, Perplexity, Claude, Gemini | 10 (ChatGPT, Perplexity, Claude, Gemini, Grok, DeepSeek, Copilot, Mistral, Meta AI, Google AI) |
| Competitor tracking | Yes | Basic | Yes | Yes |
| Prompt volume / difficulty scores | Yes | No | No | Yes |
| Content gap analysis | No | No | No | Yes |
| Built-in content generation | No | No | No | Yes |
| AI crawler logs | No | No | No | Yes |
| Reddit & YouTube tracking | No | No | No | Yes |
| ChatGPT Shopping tracking | No | No | No | Yes |
| Traffic attribution | No | No | No | Yes (GSC, snippet, server logs) |
| Page-level citation tracking | Yes | No | No | Yes |
| Multi-language / multi-region | Yes | Limited | Limited | Yes |
| Free trial | Yes | Yes | Yes | Yes |
| Starting price | ~$200+/mo | ~$49/mo | Custom | $99/mo |
| Best for | Enterprise analytics | Beginners | Mid-market monitoring | Full-cycle optimization |
A few things stand out from this table. First, Otterly.AI is missing a lot of the features that matter once you move past basic monitoring. Second, Profound and AthenaHQ are both strong on monitoring but stop short of helping you do anything about what they find. Third, Promptwatch is the only platform with content generation, crawler logs, Reddit/YouTube tracking, and traffic attribution all in one place.
Pricing: what you actually pay
This is where the conversation gets uncomfortable for some vendors.
Profound doesn't publish pricing openly, but independent reviews (including a 21-day head-to-head test by ContentMonk) put it at roughly 48% above market rate. Features like agent analytics and shopping tracking are locked behind higher tiers. For enterprise teams with budget, it's defensible. For everyone else, it's a lot.
Otterly.AI starts around $49/month, which makes it accessible. But you get what you pay for: no prompt volume data, no content gap analysis, no crawler logs. It's a monitoring dashboard, not an optimization platform.
AthenaHQ uses custom pricing, which typically means "contact sales." That's fine for enterprise buyers, but it creates friction for smaller teams trying to evaluate the tool quickly.
Promptwatch has transparent, published pricing: $99/month for the Essential plan (1 site, 50 prompts, 5 articles), $249/month for Professional (2 sites, 150 prompts, 15 articles, crawler logs, city/state tracking), and $579/month for Business (5 sites, 350 prompts, 30 articles). A free trial is available. Annual billing brings the price down further.
For most marketing teams, the $249 Professional plan is the relevant comparison point. At that price, you get monitoring, content generation, crawler logs, and traffic attribution. That's a lot of functionality for a single subscription.
The monitoring-only problem
Here's the thing that doesn't get said enough: knowing you're invisible in AI search is not the same as fixing it.
Profound, Otterly.AI, and AthenaHQ will all tell you that ChatGPT doesn't mention your brand when someone asks "what's the best [your category] tool." That's valuable information. But then what?
Most teams end up exporting a CSV, handing it to a content writer, and hoping for the best. There's no structured way to go from "we're missing from these prompts" to "here's the content that will get us cited."
Promptwatch is built around closing that gap. The Answer Gap Analysis shows you exactly which prompts competitors appear in that you don't. The built-in AI writing agent then generates articles, listicles, and comparisons grounded in real citation data from over 880 million citations analyzed. The content isn't generic SEO filler — it's specifically engineered to match what AI models want to cite.
After publishing, you track whether your new content starts getting cited, and which AI models pick it up first. Traffic attribution (via a code snippet, Google Search Console integration, or server log analysis) connects those citations to actual revenue.
That's a complete workflow. The other three platforms give you step one.
Where each platform wins
Profound wins on analytics depth
If you need the most comprehensive AI visibility data available, Profound is genuinely hard to beat. Its engine coverage is the broadest, its prompt volume data is detailed, and its reporting is built for teams that present to executives. If you're a large brand with a dedicated AEO team and a budget to match, Profound makes sense.
The limitation is that it's a reporting tool. It tells you what's happening. It doesn't help you change it.
Otterly.AI wins on simplicity
For a small team or a solo marketer who wants to start tracking AI visibility without a lot of setup, Otterly.AI is the easiest on-ramp. The interface is clean, the price is low, and you can be up and running in under an hour.
The tradeoff is that you'll outgrow it quickly. Once you want to understand prompt difficulty, track which pages are being cited, or generate content to improve your visibility, you'll need to switch.
AthenaHQ wins on competitor displacement tracking
AthenaHQ has a specific strength: showing you when a competitor is being recommended instead of you, and in what context. For brand and PR teams that want to understand how AI models perceive their competitive position, that's useful framing.
But like Profound, it stops at the insight layer. There's no path from "AthenaHQ told us we're losing to Competitor X on this prompt" to "here's the content we published to fix it."
Promptwatch wins on end-to-end optimization
The case for Promptwatch is straightforward: it's the only platform here that treats AI visibility as a problem to solve, not just a metric to track.
The crawler logs alone are something most competitors don't offer. Seeing exactly which pages ChatGPT's crawler has visited, which ones returned errors, and how often they return gives you a technical foundation that pure monitoring tools can't provide.
Add in Reddit and YouTube tracking (which surfaces the discussions that actually influence AI recommendations), ChatGPT Shopping monitoring, and query fan-outs that show how one prompt branches into sub-queries, and you have a platform that's genuinely different from the rest.
Who should use which platform
Use Profound if: You're an enterprise brand with a dedicated AEO team, you need the deepest possible analytics, and budget isn't a constraint. You're comfortable supplementing it with a separate content workflow.
Use Otterly.AI if: You're just starting out, you want to understand the basics of AI visibility monitoring without committing to a large budget, and you're okay with limited features for now.
Use AthenaHQ if: Competitor displacement is your primary concern, you're in a competitive category where knowing who's winning which prompts matters most, and you have a content team that can act on the data independently.
Use Promptwatch if: You want to actually improve your AI visibility, not just measure it. If you need to go from "we're invisible" to "we're getting cited" without stitching together five different tools, Promptwatch is built for that workflow.
A note on the broader market
These four platforms aren't the only options. Tools like Peec AI, Search Party, Semrush's AI Toolkit, and Ahrefs Brand Radar all have a presence in this space. Semrush and Ahrefs are worth mentioning specifically because they're tools most marketing teams already use — but their AI visibility features use fixed prompts and lack traffic attribution, which limits their usefulness for serious GEO work.
For teams that want something more specialized than Semrush but aren't ready for enterprise pricing, the Profound vs Promptwatch comparison is usually the real decision. Profound has more analytics depth at the top end; Promptwatch has more practical utility for teams that need to ship content and show results.
The bottom line
The AI visibility platform market in 2026 is splitting into two camps: monitoring tools and optimization platforms. Profound, Otterly.AI, and AthenaHQ are all, to varying degrees, monitoring tools. They're good at telling you where you stand. Promptwatch is trying to be something different — a platform where you can find the gap, fix it, and prove it worked.
Whether that distinction matters depends on what you're trying to do. If you need a dashboard to report on AI visibility to stakeholders, any of these will work. If you need to actually move the number, the choice gets clearer.
The free trials across all four platforms are genuine — take them up on it. Run the same set of prompts through each tool and see what you get back. The difference between a monitoring dashboard and an optimization platform becomes obvious pretty quickly when you're staring at a gap you don't know how to close.
