Key takeaways
- Otterly.AI ($29/mo) is the cheapest way to find out you have a visibility problem, but it stops at reporting -- you still have to fix things yourself.
- Scrunch AI ($250/mo, now owned by Sitecore) goes furthest into serving AI-optimized content directly to crawlers through its Agent Experience Platform, but users report the insights can be confusing and hard to act on without guesswork.
- AthenaHQ ($295/mo) leans hardest into "what do I do next" with its Action Center and a predictive Athena Citation Engine that scores content before you publish it.
- All three are monitoring-first tools at heart. None of them write and publish content for you the way agentic platforms are starting to.
- If execution matters more than measurement, it's worth comparing these against tools built around a Content Agent model before you commit a budget.
The question nobody asks before buying
Every AI visibility tool demo looks the same. Someone shows you a dashboard. A chart ticks up. A chart ticks down. Your brand shows up in 12% of tracked prompts on ChatGPT and 34% on Perplexity, and there's a little red dot next to "competitor X is winning the comparison prompts." It's satisfying in the way a fitness tracker is satisfying. You now know a number.
What almost nobody covers in the sales call is: then what? You know you're losing the "best project management software for remote teams" prompt to a competitor. Great. Do you rewrite a page? Publish a new one? File a ticket with engineering to fix your robots.txt? Wait three weeks and check again?
Scrunch AI, Otterly.AI, and AthenaHQ all sit in the same category -- AI search visibility monitoring -- but they answer that "then what" question very differently, and the gap between them is bigger than the pricing pages suggest.
What each tool actually is
Otterly.AI: the honest monitor
Otterly is the one most people start with because it's cheap and doesn't pretend to be more than it is. The Lite plan is $29/month for 15 tracked prompts across ChatGPT, Google AI Overviews, Perplexity, and Microsoft Copilot, with daily tracking and unlimited team seats. Standard jumps to $189/month for 100 prompts, multi-country tracking, and access to a Google Looker Studio connector. Premium runs $489/month for 400 prompts.
Worth flagging: Claude, Gemini, and Google AI Mode aren't included by default on any tier. They're paid add-ons, ranging from $9/month (Gemini on Lite) up to $439/month (Claude on Premium). So the sticker price understates what full-engine coverage costs once you add the models everyone actually wants tracked in 2026.
Otterly's MCP server and "Agent Analytics Events" (tracking when AI agents, not just humans, visit your site) start on the Standard tier -- a genuinely useful feature for teams who want to see crawler behavior alongside citation data.
What it doesn't do: fix anything. One industry roundup put it bluntly -- "Otterly tells you what's happening. It does not help you fix it." That's not a knock, it's the product's honest positioning. You get clean, affordable data and you're expected to bring your own content team.
Scrunch AI: the widest platform, with a catch
Scrunch (acquired by Sitecore on June 3, 2026, and now sold under Sitecore's DXP umbrella) is the most ambitious of the three on paper. The Core plan is $250/month for 4 LLMs (ChatGPT, Perplexity, Google AI Overviews, Copilot), 125 prompts, 5,000 responses per month, one page optimization per month, basic content generation, and five site audits. Agency Core runs $500/month per Scrunch's own FAQ. Enterprise, custom-priced, unlocks nine LLMs, unlimited site audits, an API/CLI, and SSO.
The headline feature is the Agent Experience Platform (AXP), which detects when an AI crawler or agent hits your site and serves it an AI-optimized version of the page in real time, at the edge. It's a genuinely different approach from "monitor, then manually rewrite." Scrunch also ships hallucination detection, flagging moments when an AI model says something false about your brand, which is a real gap most competitors ignore.
But the reviews tell a more complicated story. A hands-on review from Profound found that some tracked prompts returned "confusing at best" insights -- competitor mentions with no clear next step, requiring "a ton of guesswork and manual work" even after contacting support. G2 reviewers flag missing report exports for non-technical users, and at least one reviewer described contract terms shifting mid-negotiation, with certain models locked behind higher tiers that weren't made clear upfront. At $250/month, Scrunch also sits well above the category median (one tracker puts the GEO-tool median around $85.50/month), so you're paying enterprise prices for a tool some users say still needs hand-holding to turn into action.
AthenaHQ: closest to "do something about it"
AthenaHQ is the one most consistently described across independent roundups as action-oriented. It now has a genuine free tier (Essential), something it didn't have a year ago. Starter is $295/month for roughly 3,600 credits (1 credit equals 1 AI response across most engines; Claude costs 5 credits per response, which adds up fast if Claude matters to your audience). Enterprise is custom and adds the Athena Citation Engine, multi-region tracking, executive BI dashboards through Tableau or Power BI, and a dedicated Slack channel with a 2-hour SLA.
The Action Center is the differentiator: on-page and off-page GEO tasks, dynamic AI crawler access management through smart robots.txt and llms.txt files, and a content optimization agent. Launched September 29, 2025, the Athena Citation Engine is arguably the most interesting single feature across all three tools -- it's a model trained on millions of AI search results that predicts how likely a piece of content is to get cited before you publish it, turning what used to be a guess into a number you can act on.
AthenaHQ leans hard on self-published case studies, and it's worth reading them as marketing rather than audited proof. Rootly reports a 10x citation-rate increase (3% to 30%) and $126K in incremental equivalent media value. AutoRFP.ai reports a 10x jump in ChatGPT-referred traffic and says meaningful reporting appeared within a week, with actionable steps ready within two. Cozy Earth reports a 3.6x increase in sleepwear-category mentions with a two-person content team. None of these publish a baseline, a control group, or a prompt set alongside the number, which is standard for the category, not a unique flaw in AthenaHQ, but it means you should treat the multiples as a directional story, not evidence.
Side-by-side comparison
| Tool | Starting price | Engines included | Action layer | Standout feature | Known weak spot |
|---|---|---|---|---|---|
| Otterly.AI | $29/mo | ChatGPT, AIO, Perplexity, Copilot (Claude/Gemini/AI Mode cost extra) | None -- pure monitoring | MCP server, Agent Analytics Events | You still execute everything yourself |
| Scrunch AI | $250/mo | 4 LLMs on Core, 9 on Enterprise | Agent Experience Platform (AXP), hallucination detection | Serves AI-optimized content directly to crawlers | Users report confusing insights, guesswork to act, shifting contract terms |
| AthenaHQ | Free tier; $295/mo Starter | 8+ engines | Action Center, Athena Citation Engine (ACE) | Predicts citation probability before you publish | Case studies self-published, no baseline or control disclosed |
Why the "action layer" question matters more than the feature list
Here's the thing that gets lost in feature comparisons: all three of these tools are still, fundamentally, measurement instruments. Even the ones with an "action" feature are mostly generating recommendations or serving pre-written variants, not writing and publishing new, GEO-optimized content to your CMS on a schedule. That's a meaningfully different job.
It matters because of how fast the underlying answer engines are moving. Promptwatch's own data on ChatGPT's citation mix in August 2026 shows product pages dropped from roughly 30% of citations to about 25% by month's end, while how-to content more than doubled, from 4.3% to 9.1% of citations, and social posts collapsed from 4.4% to under 1% after August 14, the same day Reddit's citation share in ChatGPT fell off a cliff (from about 4% to 0.5%, per Promptwatch's Reddit citation data). If your monitoring tool tells you "Reddit mentions are down" in September but doesn't tell you to reallocate that budget into how-to content, you're a month behind before you've even opened a doc.
The number of citation slots per answer also varies a lot by engine, which changes what "winning" even means. ChatGPT cites around 5 sources per web-search response, Google AI Overviews cites about 10, and Perplexity sits close to 10 as well, day after day, which makes it the most stable engine to benchmark GEO experiments against (see Promptwatch's average sources per response data). Microsoft Copilot, by contrast, has swung from under 2 sources to nearly 17 within a matter of weeks, meaning a single snapshot from any of these three tools could be describing a moment that's already gone.
Where each tool actually fits
Otterly makes sense if you're testing the waters, you have an internal content team that's already capable of acting on gaps, and you just need a cheap, honest signal. It's a reasonable first thermometer, not a program.
Scrunch makes sense if you're managing multiple brands or agency clients and the AXP's real-time crawler-serving genuinely matters to your stack, and if you have the patience (and budget) to work through a learning curve. Read the G2 reviews before you sign anything, particularly around locked-tier models and pricing terms.
AthenaHQ makes sense if you want the clearest path from
