Key takeaways
- "Tracks 9 AI engines" on a pricing page rarely means your entry-level plan does. Profound, Peec, and Scrunch all gate Claude, Gemini, Copilot, Grok, and DeepSeek behind Growth or Enterprise tiers, so the advertised coverage and the coverage you can actually afford are two different things.
- Each engine has a different citation appetite: ChatGPT cites roughly 5 sources per response while Google AI Overviews and Perplexity cite about 10, according to Promptwatch's cross-engine data. A tool that only watches ChatGPT is measuring the tightest, most competitive slot in the market and ignoring the roomier ones.
- Citation behavior shifts overnight, not gradually. Average citations per ChatGPT response dropped about 27% within a day of the GPT-5.3 rollout in March 2026, which is a strong argument against one-off audits and in favor of continuous tracking.
- Reddit's role inside ChatGPT citations went from roughly 3.8% to under 1% between August 7 and 14, 2026, while its decline in Google's AI surfaces has been far more gradual. Platforms with stale citation data will still be telling clients to "build a Reddit presence" based on assumptions that no longer hold.
- If you want a platform that goes beyond tracking and actually helps fix visibility gaps, that combination of crawler logs, content generation, and CMS publishing narrows the list considerably.
Why multi-model coverage is the whole point
A year or two ago, "AI visibility" mostly meant ChatGPT. That's no longer true, and it was never a safe bet anyway. Buyers now split their research across ChatGPT, Gemini, Claude, Perplexity, Copilot, and Google's AI Overviews and AI Mode, and each one behaves like a different search engine with its own retrieval logic, source preferences, and volatility.
Here's the part that surprised me when I dug into the data: these engines aren't just different in scale, they're different in kind. Promptwatch's research on average sources per response shows ChatGPT citing around 5 sources per web-search-enabled answer, while Perplexity and Google AI Overviews sit near 10, almost double. Microsoft Copilot is the wild card, swinging from under 2 sources per response to nearly 17 within a few weeks, evidence that Microsoft is still rebuilding how Copilot attributes its answers.
What that means practically: if your monitoring tool only covers ChatGPT, you're fighting for one of the tightest, most contested citation inventories in AI search, and you have no idea whether you're already showing up comfortably in the more generous engines. Multi-model coverage isn't a nice-to-have feature on a pricing page. It's the difference between an accurate picture of your AI visibility and a partial one.
The catch: advertised coverage vs. what you actually get
Almost every vendor in this category lists an impressive top-line engine count, then gates most of it behind a higher tier. This is the single biggest trap buyers fall into.
Profound advertises up to 9-11 engines, but its $99/month Starter plan is ChatGPT only. You need the $399/month Growth plan just to add Perplexity and Google AI Overviews, and Claude, Gemini, Copilot, Grok, and DeepSeek are Enterprise-only with custom pricing that industry estimates put well north of $2,000/month.
Peec AI lists seven possible engines but caps every self-serve tier at three, with a fourth engine available as a paid add-on ($35-$165/month depending on plan). Scrunch AI's $250/month Core plan covers four engines (ChatGPT, Perplexity, Google AI Overviews, Copilot); Gemini, Claude, Meta AI, and Google AI Mode require Enterprise. Semrush's standalone AI Visibility Toolkit lists five engines on its documentation, but independent reviews report Gemini as still rolling out and Perplexity or Claude support as inconsistent in practice.
The lesson: don't shop by the number on the homepage. Price out the specific engines your buyers actually use, on the tier you can realistically afford, before you commit.

Platform-by-platform notes
Promptwatch
Promptwatch tracks ChatGPT, Gemini, Claude, Perplexity, Grok, DeepSeek, Mistral, Microsoft Copilot, Google AI Overviews, Google AI Mode, Meta Llama, and AI coding assistants like Claude Code and OpenCode, without splitting that coverage across tiers the way most competitors do. The bigger differentiator, though, isn't the engine count, it's what happens after you find a gap.
Most tools in this category stop at "here's your mention rate." Promptwatch adds AI crawler logs (so you can see whether ChatGPTBot, ClaudeBot, or PerplexityBot are even reaching your pages), citation trend analysis classified into 22 content types, Reddit and YouTube-specific citation reports that most competitors skip entirely, and Content Agents that draft and publish GEO-optimized articles straight to Webflow, Framer, or WordPress. Crisp, one of its customers, used this to scale to 5-10 published articles a day and reported 2x higher conversion rates from AI-driven traffic than from traditional channels.
At $95/month for the Essential plan, you get all-LLM tracking, 50 prompts, and MCP/API access, no engine paywall. The $245/month Professional tier adds state and city-level tracking, automated content generation, and ChatGPT Shopping insights. For teams that want to go from "we're invisible in AI search" to "here's the content roadmap that fixes it" without stitching together three separate tools, this is the more complete option of the ones covered here.
Profound
Profound is a solid enterprise pick if reporting depth matters more than budget. The catch, covered above, is that its advertised multi-engine coverage lives almost entirely on the Enterprise tier, and that tier isn't priced publicly. If you're a small or mid-market team evaluating Profound based on the $99/month headline, know that you're looking at ChatGPT-only visibility until you upgrade.
Profound
Scrunch AI
Scrunch's Core plan at $250/month covers four engines and includes technical site-audit features, which is useful if crawlability, not just prompt visibility, is your concern. But the jump to seven-plus engines (adding Claude, Gemini, Meta AI, Google AI Mode) again requires Enterprise, with SOC2 Type II and SSO bundled in at that tier for the compliance-conscious.
Peec AI
Peec is a reasonable starting point for European teams (pricing is quoted in euros first) that want to test the waters before committing to full multi-model tracking. Its per-engine add-on pricing is at least transparent, which is more than you can say for most Enterprise quotes in this category.
AthenaHQ
AthenaHQ's free tier and $295/month Starter plan both cover a genuinely broad set of engines early, which is unusual. The tradeoff, per independent reviews, is that the Starter plan's 3,600 monthly credits can run out in about two weeks under real monitoring load, so budget for the next tier up if you're tracking more than a handful of prompts.
Otterly.ai
At $29/month, Otterly is the cheapest entry point in this whole category, and it does cover four engines including Copilot, which fewer budget tools bother with. It's a fine starting point if you just want a pulse check before investing in something deeper.
Otterly.AI
Semrush AI Visibility Toolkit
If you're already paying for Semrush, the AI Visibility Toolkit add-on at $99/month per domain is a low-friction way to get a first look at AI citations without adding a new vendor relationship. Just verify current engine support directly, since third-party reviews and Semrush's own documentation don't fully agree on how consistently Gemini and Perplexity tracking actually works.
What actually changes week to week (and why snapshots lie)
Here's something that doesn't get enough attention in buying guides: the ground you're measuring moves fast. Promptwatch's tracking of the GPT-5.3 rollout in March 2026 recorded a roughly 27% drop in average citations per ChatGPT response within a single day, with no recovery a month later. That's not a slow drift, that's a platform decision that reshaped the competitive landscape overnight.
The Reddit story is even more dramatic. Reddit held a steady 3.8% share of ChatGPT Search citations through early August 2026, then collapsed to about 0.5% by August 14, an 86% relative drop in a week, coinciding with ChatGPT's adoption of site: search operators at scale on August 8. Meanwhile Google's AI Overviews and AI Mode showed a much gentler decline in Reddit citations over the same window. Any advice you got in early 2026 telling you to "build a Reddit presence for ChatGPT visibility" needs a second look, and it's a good test of whether your monitoring tool's data is actually fresh or just cached from a few months back.
This is really the core argument for continuous, multi-model monitoring over any kind of periodic manual check. If you're just typing prompts into ChatGPT once a month to see if your brand shows up, you're going to miss shifts like this entirely, and you'll be optimizing for a version of the algorithm that no longer exists.
Don't ignore the crawler layer
A visibility score is a lagging indicator. If AI crawlers can't reach your pages in the first place, no amount of content strategy will fix your citation rate. OpenAI's crawlers still made up about 79.8% of verified AI crawler requests in early September 2026, down from 94.8% in June, which tells you the other players (Anthropic, Meta, Perplexity, Mistral) are gaining real ground. Meta's new web indexer went from roughly 2% to nearly 38% of tracked AI crawler traffic between mid-July and early August 2026, a genuinely new crawler most site owners haven't checked their robots.txt against yet.
This is why a platform that only reports on citations, without also showing you crawler logs, is only giving you half the picture. If a brand monitoring tool doesn't show which bots are hitting your site, what they're reading, and where they're erroring out, you're diagnosing symptoms without seeing the cause.
How to pick, based on what you actually need
If you're a small team just testing whether AI visibility matters for your category, start cheap: Otterly.ai at $29/month or AthenaHQ's free tier will tell you fast whether you show up at all.
If you're already committed and need the full picture, real multi-model coverage without a paywall, plus the tools to actually close the gaps you find, that combination points toward Promptwatch. Its Essential plan starts at $95/month with all LLM tracking included, and the jump to Professional at $245/month adds automated content generation and shopping insights rather than just unlocking more engines you were already promised.
If your organization needs enterprise compliance features (SSO, SOC2) more than it needs a lower entry price, Profound or Scrunch's Enterprise tiers are worth a custom quote, just budget for a number well above the advertised starting price.

A few questions worth asking any vendor before you sign
How many of your advertised engines are actually included at the tier I'm buying? Ask for the exact list, in writing, not the marketing page's aggregate count.
How fresh is your citation data, and how often do you re-run prompts? Given how fast things like the Reddit citation collapse happened, weekly refreshes are the bare minimum; daily is better.
Do you show crawler-level data, or only citation-level data? If a vendor can't tell you whether GPTBot or ClaudeBot successfully crawled a given page, they're missing the layer that explains most visibility problems.
What happens after you find a gap? Some platforms stop at the dashboard. Others, Promptwatch among them, generate content briefs or full articles and publish them for you. Decide up front whether you want a monitoring tool or an execution partner, because that choice will shape which platform on this list makes sense for your team.
