You ranked #1 on Google. Your competitor doesn't rank at all. And yet ChatGPT recommends them and not you — every single time someone asks which tool to use. There's no notification when this happens. No alert. No traffic drop you can point to. Your brand is invisible in the answers your buyers are getting, and the tools you've been using to track performance weren't built to tell you. The category of LLM visibility tools exists to close that gap. Here's how they compare.
What to Look for in an LLM Visibility Tool
Before comparing tools, it helps to be precise about what you're actually measuring. What LLM visibility means at the technical level is different from what matters operationally. For a marketing team, the relevant metrics are:
- Engine coverage — Which AI platforms does the tool monitor? ChatGPT and Perplexity are not the same audience. Google AI Overviews affects different queries than Claude. A tool that monitors one engine gives you a partial picture.
- Prompt granularity — Does it track aggregate "your brand was mentioned" counts, or does it show you which prompts trigger your brand and which don't?
- Citation vs. mention — Is your brand named in passing, or is your URL actively being cited as a source? These have very different implications for content strategy.
- Update frequency — Daily tracking vs. weekly snapshots: the difference matters when a competitor publishes new content and AI engines reprioritize citations within days.
- Action pathway — Does the tool tell you what to do next, or just what's happening? A monitoring dashboard with no optimization path shifts the work back to your team.
- Price vs. coverage — The newest tools in this category charge $295–$2,500/month for enterprise plans. Understanding whether that's justified requires knowing exactly what you're getting.

Tool #1: Allable — LLM Visibility Built into Your Marketing Platform
Most LLM visibility tools are dashboards that tell you what's happening. Allable is different because it closes the loop: you can see where your brand isn't being cited, and then act on that information in the same platform — through content creation, keyword research, and campaign optimization — without switching tools.
The AI Visibility module monitors your brand across ChatGPT, Perplexity, and Gemini. It shows citation rates by prompt cluster, which competitors are being cited instead of you, and where the specific content gaps are that explain the discrepancy. Most LLM monitoring tools hand off the "what to do next" to another workflow. Allable doesn't.
Key features:
- LLM brand monitoring across ChatGPT, Perplexity, and Gemini
- Citation rate tracking by prompt and topic cluster
- Competitor share of voice comparison in AI answers
- Integrated content optimization — create or update articles that move your citation rate
- Full platform: AI brand visibility, keyword research, campaigns, social, analytics
Pricing:
- Free — core features, limited LLM visibility queries
- Pro: ~$33/month — full AI visibility monitoring, content optimization
- Business: ~$98/month — advanced reporting, team collaboration, expanded tracked prompts
Verdict: The best LLM visibility tool for marketing teams who need monitoring and optimization in a single platform. The price-to-coverage ratio is the strongest in the category.
Tool #2: Profound — Enterprise Brand Narrative Tracking
Profound's approach to AI brand visibility is different from most tools. Instead of focusing on whether your brand is cited, Profound is built around understanding how AI systems describe and narrate your brand — the language models use, the sentiment they express, and the context they place you in.
That makes Profound the right tool for brands where reputation management is as important as citation rate. A pharmaceutical company that appears in AI answers described as "controversial" has a different problem than a brand that simply doesn't appear. Profound is one of the few tools with the depth to differentiate.
Key features:
- AI Citation Visibility: which prompts trigger citations, across which AI engines
- Brand narrative monitoring: sentiment, framing, and language AI systems use about your brand
- Source Categorization: which content types and authority levels AI engines favor
- Outreach Intelligence: top-cited publishers in your category (PR/content strategy input)
- Conversation Explorer: prompt demand analysis — what questions drive AI answers in your category
Pricing:
- Starter: $99/month — ChatGPT only, 1 region, 1 seat
- Growth: $399/month — 3 engines, 6 optimized articles/month included
- Enterprise: custom — 10+ engines
G2 rating: 4.6/5
Where it struggles: Starter is ChatGPT-only in 2026, when Perplexity and Google AI Overviews drive significant volume. Growth at $399/month is a large step. Verdict: Best for enterprise brands and PR teams where narrative quality matters as much as citation volume.
Tool #3: Ahrefs Brand Radar — AI Visibility for Ahrefs Users
Ahrefs launched Brand Radar to extend its backlink and keyword data into the AI visibility space. For teams already standardized on Ahrefs, Brand Radar is the most natural entry point — the data lives alongside everything else you already track.
Key features:
- AI Share of Voice tracking across 6 engines
- Brand mention trend analysis vs. competitors
- Integration with Ahrefs' existing site data (backlinks, keywords, traffic)
- No free trial
Pricing: Ahrefs requires an active paid plan ($129/month minimum for Lite). Brand Radar is an add-on at approximately $199/month, bringing the minimum to ~$328/month.
Verdict: The best LLM visibility choice for existing Ahrefs subscribers. For teams starting fresh, the total cost and lack of trial work against it.
Tool #4: Am I On AI — ChatGPT Visibility Specialist
Am I On AI is a focused tool built specifically around ChatGPT brand visibility. Rather than broad multi-engine monitoring, it tracks how your brand appears in ChatGPT responses with more granularity — position, frequency, context, and what it calls "mindshare."
Key features:
- ChatGPT brand visibility tracking (mindshare metrics)
- Position, frequency, and context of brand mentions
- Trend tracking over time
- 7-day trial available
Pricing:
- Standard: $349/month
- Enterprise: $2,500/month
Where it struggles: At $349/month for ChatGPT-only coverage, the price-to-scope ratio doesn't compete with multi-engine tools. Verify that ChatGPT is genuinely your most important AI channel before committing.
Verdict: Justified for brands where ChatGPT-specific mindshare is the primary strategic metric. For multi-engine coverage, alternatives provide better value.
Tool #5: AthenaHQ — Enterprise LLM Visibility with 9-Engine Coverage
AthenaHQ is a Y Combinator-backed GEO/AEO platform that leads the market on engine breadth. It monitors 9 AI models simultaneously: ChatGPT, Perplexity, Google AI Overviews, AI Mode, Gemini, Grok, Claude, Copilot, and DeepSeek. Over 90 Fortune 500 companies use the platform.
What makes AthenaHQ distinct is Source Intelligence: it doesn't just tell you your brand was cited — it identifies the specific URLs the AI engine used as sources when generating that citation. That granularity lets you understand why you're being cited at the content level.
Key features:
- 9-engine coverage (broadest in market at this price point)
- Share of voice, mention rate, average position, citation rate metrics
- Source Intelligence: exact URLs AI engines cite when mentioning your brand
- Full AI answer storage — the complete AI response, not just the mention
- API access, content optimization agent
- Free trial: 300 credits (one-time grant, no credit card required)
Pricing:
- Free: 300 credits (one-time, no credit card required)
- Starter: $295/month — 9 models, API access, content optimization agent
- Enterprise: custom — expanded limits, strategic support
G2 rating: 4.9/5 | 90+ Fortune 500 companies
Where it struggles: No middle tier. Free → $295/month with nothing in between. Best features gated to Enterprise.
Verdict: The strongest choice for enterprise teams that need 9-engine coverage and source-level citation intelligence. The $295/month floor makes it expensive for smaller teams.

Which LLM Visibility Tool Is Right for Your Team?
Starting out, need to establish a baseline: Start with Allable's free plan or OtterlyAI ($29/month). Both give you multi-engine coverage without significant investment.
Running an AI visibility audit for stakeholders: Allable (integrated reporting), Semrush AI Toolkit (if you're already in Semrush), or Profound (enterprise narrative depth).
Need the broadest engine coverage: AthenaHQ at $295/month covers 9 engines including DeepSeek and Grok. For enterprises where each AI engine matters, AthenaHQ's breadth is worth the price.
Already on Ahrefs: Brand Radar is the path of least resistance — AI visibility data alongside your existing content and link data.
ChatGPT is your primary concern: Am I On AI goes deepest on ChatGPT-specific mindshare. But at $349/month, verify ChatGPT genuinely drives more for your audience than Perplexity or Google AI Overviews before committing.
Want to monitor and act without switching tools: Allable is the only platform where LLM visibility data connects directly to content creation, keyword research, and campaign management. An AI visibility audit becomes a weekly routine, not a quarterly project.
FAQ: LLM Visibility Tools
What's the difference between LLM visibility tools and traditional SEO rank trackers? Traditional rank trackers show where your pages appear in Google's blue-link results. LLM visibility tools track whether your brand is cited inside AI-generated answers. Both track your presence in different parts of the same ecosystem. For a full explanation, see what LLM visibility means.
How often should I check my LLM visibility metrics? Monthly reviews work for most teams. For brands in fast-moving categories (SaaS tools, fintech, health tech), weekly tracking catches shifts faster. More frequent monitoring helps when you're actively publishing content to build AI visibility — you'll see whether it's working within days.
Do LLM visibility tools work across all AI platforms? Coverage varies. OtterlyAI (7 engines) and AthenaHQ (9 engines) lead on breadth. Profound and Allable cover the highest-volume platforms. In 2026, ChatGPT, Perplexity, and Google AI Overviews drive the majority of AI search traffic — tools covering these three handle most of what matters.
How do LLM visibility tools know when my brand is mentioned? Most tools send tracked prompts to AI platforms on a schedule and analyze the responses. More sophisticated tools like AthenaHQ also trace which specific URLs the AI cites as sources — so you can see not just that you were mentioned, but which of your pages the AI is reading to form its answers.
What's the most affordable multi-engine LLM visibility tool? OtterlyAI at $29/month covers 7 engines including ChatGPT, Perplexity, Gemini, Claude, and Copilot. Allable's free plan covers ChatGPT, Perplexity, and Gemini with no initial investment.
Should I use an LLM visibility tool or an AEO tool? The categories overlap. LLM visibility tools focus on monitoring. AEO tools often include monitoring and optimization. Allable covers both in one platform.
The Verdict: Track First, Then Act
The LLM visibility tool market in 2026 has a problem: most tools are excellent at telling you what's happening, and limited at telling you what to do next. You'll see citation rates and competitor share of voice — and then export that data to a content brief, hand it to a writer, and wait. The feedback loop is manual.
The teams getting the fastest improvement in AI search visibility are the ones where monitoring data flows directly into content action. That's the case for monitoring + content platforms (Allable, Writesonic, Frase with GEO scoring) and less so for pure-play trackers.
If you're just getting started: Allable's free plan or OtterlyAI at $29/month let you build a baseline before committing to a premium tool. If you already know where you stand and need depth: Profound for narrative intelligence, AthenaHQ for source-level citation analysis across 9 engines.
Stop guessing — track your LLM visibility in real-time with Allable. The free plan covers ChatGPT, Perplexity, and Gemini, with citation tracking and content optimization in the same workspace.
