Best LLM Visibility Tools in 2026: A Hands-On Comparison

AI answers now drive discovery. We compared the best LLM visibility tools on what they track, what they cost, and which one actually changes what AI says.

MesmerToolsJune 17, 202613 min

We spent two weeks pulling apart every serious LLM visibility tool on the market, because in 2026 your buyers ask ChatGPT before they ask Google. The thing nobody says out loud: almost all of these tools measure where you stand in AI answers, and exactly one of them actually tries to change it.

Quick Take

TL;DR: If you want to move the needle instead of just watching it, slopmog is our top pick: it seeds authentic Reddit and YouTube comments that feed the sources AI engines actually cite.

For pure measurement: Profound has the deepest data, Scrunch AI has the widest engine coverage, and Peec AI is the best value for agencies and EU teams.

Two different jobs hide under one category

Before the list, the honest framing that shaped our ranking. The phrase “llm visibility tool” covers two very different jobs. Job one is to measure your visibility in AI answers: which prompts mention you, which engines cite you, how your share of voice trends. Profound, Scrunch AI, Peec AI, Otterly.ai, Goodie AI, and Brand24 all do this, with different depth.

Job two is to actually change what AI says about you. That means putting credible, brand-relevant material into the sources these models read. Reddit is the single most-cited source in Google AI Overviews and Perplexity, showing up in roughly a fifth of AI Overview responses, so a believable mention in the right thread has a real path into an AI answer. slopmog is the only tool here built for job two, which is why we rank it first and then judge the measurement tools on their own terms.

1. slopmog The One That Acts, Not Just Measures

Acts on visibilityReddit + YouTubeHuman approvalFree comment toolFrom $49/mo

Every other tool in this roundup is a dashboard. slopmog is the one tool that tries to change the source material that AI engines read. It finds Reddit and YouTube threads where your brand is genuinely relevant, drafts native-sounding comments with Claude, and posts them from aged accounts only after you approve each one.

The logic is direct. If Reddit is the most-cited source in AI Overviews and Perplexity, then earning credible mentions on Reddit is a more direct lever on AI search visibility than another chart telling you that you are losing. Its opportunity discovery scores the past 24 hours of posts by relevance, and an “HV” pipeline queries ChatGPT, Claude, and Gemini to find the exact threads those models already cite, then targets those.

There is also a free Reddit Comment Generator (no signup, five free per hour) if you want to feel the workflow before paying. Pricing starts at $49/mo and runs to $199/mo for the full analytics tier.

What makes slopmog stand out

  • It acts instead of measuring: the only tool here that tries to earn AI citations rather than just report on them.
  • It targets the most-cited source: Reddit and YouTube comments aimed at the threads AI engines actually pull from.
  • Human approval before anything posts: Claude drafts the comment, but nothing goes live until you sign off, which keeps you in the loop on tone and relevance.

Pros

  • The only tool here that changes the source material instead of just tracking it
  • Targets Reddit, the single most-cited source in AI Overviews and Perplexity
  • Mandatory human approval before any comment is posted
  • Free Reddit Comment Generator and a low $49/mo entry point

Cons

  • Undisclosed brand promotion is astroturfing: FTC endorsement rules require disclosing material connections, and Reddit's TOS prohibits manipulation, so callout and removal by moderators is a real, reputational risk you must weigh
  • Early-stage and in active rebuild: YouTube support is MVP and Twitter is not live yet
  • No independent G2, Trustpilot, or Reddit reviews, and the published metrics are unaudited
  • Full AI-mention analytics are gated to the $199/mo tier

Price: From $49/mo, free Reddit comment tool with no signup

2. Profound Deepest Enterprise Analytics

Prompt Volumes10+ enginesSOC 2Enterprise

Profound is the heavyweight of AI search analytics. It serves around 10% of the Fortune 500 (Ramp, US Bank, Indeed, MongoDB, Chime), raised over $155M at a roughly $1B valuation, and won the Winter 2026 AEO Leader badge on G2 with a 4.6/5 rating across hundreds of reviews.

Its standout is “Prompt Volumes,” real consumer AI-search demand data that genuinely does not exist anywhere else. The catch is packaging. The $99 Starter is widely read as a deliberate funnel: 50 prompts on ChatGPT only is not enough to run a real program, and serious work needs the $399 Growth plan or a custom enterprise contract. There is no Reddit intelligence, which is a notable gap given how much Reddit feeds AI citations.

Pricing starts at $99/mo, with real programs landing at $399/mo and up. No free trial, sales-led for the full platform.

What Users Say:

  • - “Before Profound, AI Search was a black box. Now it’s a competitive advantage.” (George Bonaci, VP Growth, Ramp, vendor testimonial)
  • - Independent reviewers keep flagging the same thing: the $99 Starter is “a deliberate funnel,” and 50 prompts on ChatGPT only is not enough to run a real AEO program.

Pros

  • Prompt Volumes gives real AI-search demand data found nowhere else
  • Deepest analytics here: 10+ engines, daily refresh, SOC 2
  • Documented outcomes (Ramp reported a 700% increase in AI referrals)
  • Strong G2 standing and a Winter 2026 AEO Leader badge

Cons

  • The $99 Starter is a funnel; real work needs $399+ or an enterprise contract
  • No free trial and no self-serve path to the full platform
  • No Reddit intelligence despite Reddit's citation weight
  • Steep learning curve, data overload, and reported billing bugs

Price: From $99/mo, real programs at $399/mo and up, no free trial

3. Scrunch AI Widest Engine Coverage Plus an Edge Layer

7-9 enginesAXP edge deliveryHallucination detection

Scrunch AI tracks brand visibility across 7 to 9 AI engines, the broadest standard-tier coverage in this group, and pairs it with an Agent Experience Platform (AXP) that serves AI-optimized page versions to crawlers at the edge. That moves it from monitoring toward actual infrastructure, which is rare here.

The defining recent fact is the acquisition: Sitecore bought Scrunch for roughly $225M on June 3, 2026. That validates the category but adds real uncertainty, since CMS acquisitions often bundle features and raise prices. Hallucination detection, genuinely useful for regulated industries, stays locked to Enterprise, and there is no Reddit monitoring.

Pricing starts at $250/mo for 350 prompts across 7 engines, with Growth at $417/mo and custom Enterprise. A 7-day trial is available.

What Users Say:

  • - Scrunch holds the largest verified review base in this roundup (G2 4.6/5 across 50+ reviews, 76% five-star), so the broad sentiment is genuinely positive.
  • - Akamai case study: “+364% brand presence for non-branded prompts and +218% increase in citations” (vendor press release).

Pros

  • Broadest standard-tier engine coverage (7 engines at $250/mo)
  • AXP edge layer is genuinely differentiated, not just a dashboard
  • Hallucination detection matters for regulated industries
  • Largest verified review base here (G2 4.6/5, 76% five-star)

Cons

  • Post-Sitecore roadmap and pricing uncertainty after the $225M deal
  • Hallucination detection is Enterprise-only
  • Prompt math is misleading (350 prompts across 7 engines is 50 unique queries)
  • No free tier, English-focused, and no Reddit monitoring

Price: From $250/mo (7 engines), 7-day trial

4. Peec AI Best Value for Agencies and EU Teams

Unlimited seatsGDPR + EU residencyFast-growing

Peec AI is the fastest-growing challenger here. Founded in Berlin in February 2025, it raised $29M and reached roughly $4M ARR and 1,300+ customers, including Chanel, ElevenLabs, and Wix, in under a year. Reviewers keep calling it the easiest AI visibility tool to use.

Two things make it the value pick. Every plan includes unlimited seats, which is the most agency-friendly pricing in this list, and it offers GDPR compliance with EU data residency, often a hard procurement requirement in Europe. The trade-off is that it is monitoring without much optimization (its Actions feature is weak and in beta), per-engine add-ons inflate the real cost, and it is only 16 months old with a tiny review sample.

Pricing starts at €85/mo for 50 prompts across 3 base engines, with extra engines at €20 to 30 each. A 7-day trial is available.

What Users Say:

  • - “Metrics like brand mentions, impressions, and sentiment are hard to track, which is why Peec AI is powerful: it shows how LLMs are framing our brand.” (Lily Ray, VP SEO Strategy, Avisive, vendor testimonial)
  • - “The opinionated design lets you complete workflow steps efficiently and avoids feature overload.” (Ethan Smith, CEO, Graphite, vendor testimonial)

Pros

  • Unlimited seats on every plan, the best agency pricing here
  • GDPR compliance with EU data residency for European procurement
  • Praised as the easiest AI visibility tool to use
  • Founder-level Slack support and multi-country tracking below Enterprise

Cons

  • Monitoring without real optimization; Actions is weak and in beta
  • Hidden per-engine add-on costs push the real price up sharply
  • No API below Enterprise (CSV export only) and no SOC 2
  • Only 16 months old with a tiny review sample (around 9 G2 reviews)

Price: From €85/mo, extra engines €20 to 30 each, 7-day trial

5. Otterly.ai Cheapest Real Entry Point

$29/moFast setupAgency-friendly

If you just want to start tracking your AI search visibility cheaply, Otterly.ai is the entry point. Its Lite plan is $29/mo with a real 14-day trial and no card, setup takes under ten minutes, and it ships features fast (it added Google AI Mode quickly). It earned a Gartner Cool Vendor nod in November 2025 and sits at 4.8 to 4.9 on G2.

It is firmly a monitoring tool, with thin guidance on what to do with the insights. Prompt ceilings escalate cost fast (the jump from $29 to the $189 Standard plan is 6.5x), there is no retroactive or historical data, and the headline “six engines” needs paid add-ons. Worth noting the brand-name confusion with Otter.ai, which is a different product.

Pricing starts at $29/mo, with Standard at $189/mo. A 14-day trial is available with no card.

What Users Say:

  • - “Since using OtterlyAI, I’ve seen a 2x increase in both our visibility in AI search engines and incoming traffic.” (Rebecca Anderson, Instant Commerce, vendor testimonial)
  • - Independent ratings are strong but thin (G2 4.8-4.9 across about 30 reviews, Product Hunt 5.0), so read the sentiment as promising rather than battle-tested.

Pros

  • Lowest genuine entry in the category at $29/mo with a real trial
  • Very fast setup, under ten minutes to first data
  • Ships features quickly and is agency-friendly (unlimited workspaces, Looker Studio)
  • Gartner Cool Vendor and high (if thin) review scores

Cons

  • Monitoring only, with thin guidance on what to do with the data
  • Prompt ceilings escalate cost (the $29 to $189 jump is 6.5x)
  • No retroactive or historical data
  • Brand-name confusion with the unrelated Otter.ai

Price: From $29/mo, 14-day trial, no card

6. Goodie AI Most All-in-One, If You Can Afford It

Monitor + optimizeAEO writerRevenue attribution

Goodie AI is the most closed-loop platform here. It bundles monitoring, an optimization hub, a built-in AEO content writer, and revenue attribution, with customers like Dermalogica, SteelSeries, and Rathbones. Its Agentic Commerce tracking (Amazon Rufus, Google Shopping AI) is uniquely positioned for e-commerce.

The catch is cost and proof. The $399 Explorer plan is the most expensive transparent entry here (13x Otterly Lite), Pro and Enterprise pricing hide behind a demo, and independent reviews are very thin. The case-study metrics are spectacular but unaudited, and the optimization still needs in-house execution to act on.

Pricing starts at $399/mo for Explorer, with a 30-day money-back window. Pro and Enterprise are quote-only.

What Users Say:

  • - There are no independent verbatim user reviews to cite yet; the public review base is very thin (OMR shows 0 reviews).
  • - Goodie publishes case-study metrics only (Dermalogica “127% increase in AI conversions,” NoGood “335% increase in traffic from AI sources”), which are vendor-sourced and unaudited.

Pros

  • Closest to all-in-one: monitor, recommend, and generate content in one place
  • Revenue attribution on the entry tier, which is rare
  • Agentic Commerce tracking is uniquely positioned for e-commerce
  • MCP on all tiers and the longest refund window (30 days)

Cons

  • $399 Explorer is the most expensive transparent entry here
  • Pro and Enterprise pricing are hidden behind a sales demo
  • Very thin independent reviews and unaudited case-study metrics
  • Optimization still needs in-house execution to deliver

Price: From $399/mo (Explorer), 30-day money-back, higher tiers quote-only

7. Brand24 Broadest Listening, Lightest AI Analytics

25M+ sources108 languagesMature platform

Brand24 is the veteran here, a mature social listening platform (10+ years) that bolted AI-chatbot mention tracking onto an enormous monitoring engine. It pulls from 25M+ sources, handles sentiment in 108 languages, and holds strong, deep ratings (G2 4.6/5 across about 340 reviews, Capterra 4.7/5). A January 2026 MCP integration lets you query its data from ChatGPT or Claude.

The limitation is precision. Brand24 tells you that people mention you on Reddit, but not whether those conversations change what ChatGPT says about you. It is listening, not citation-level or prompt-level analytics, the sentiment NLP misses sarcasm, and low tiers carry restrictive keyword and mention caps.

Pricing starts around $149/mo (annual) for the Individual plan, with a 14-day trial and no card.

What Users Say:

  • - “The platform is intuitive, fast, and delivers valuable insights that help monitor brand reputation, track campaigns, and respond to mentions in real time.” (Capterra review)
  • - “Brand24’s filters can let irrelevant or incorrect content through, which affects the accuracy of insights.” (Capterra review)

Pros

  • Enormous source breadth (25M+ sources) and 108-language sentiment
  • Mature and reliable with a large, deep review base (G2 4.6/5)
  • Lowest functional entry to any AI-mention tracking
  • Brand24 MCP lets you query its data from ChatGPT or Claude

Cons

  • Listening, not true AI-citation or prompt-level analytics
  • Sentiment NLP misses sarcasm (some negatives mislabeled positive)
  • Restrictive keyword and mention caps on lower tiers
  • No publishing or action tools; historical data is gated

Price: From ~$149/mo (annual), 14-day trial, no card

Final Verdict

Our pick: slopmog

After working through all seven, slopmog is our pick for one honest reason: it is the only tool that tries to change your visibility in AI answers instead of just charting it. A dashboard tells you that you are losing the AI-citation race. slopmog goes and earns the Reddit and YouTube mentions those engines actually cite, with you approving every comment first. It is early-stage, and undisclosed brand promotion carries real FTC and Reddit-moderation risk you have to weigh. But on the job that actually moves the needle, nothing else here competes.

Check out slopmog

That said, the measurement tools earn their place. Profound has the deepest enterprise data if you can absorb the funnel pricing. Scrunch AI has the best engine breadth plus a real edge layer, with the Sitecore question hanging over it. Peec AI is the value pick for agencies and EU teams, Otterly.ai is the cheapest way to start, Goodie AI is the most all-in-one if budget is no object, and Brand24 casts the widest listening net.

The smart play for most teams is to pair one of them with a way to actually earn citations. Measure with whichever tool fits your budget, then act on what you learn. Start with a free trial or two and slopmog’s free comment tool before committing to anything.

Frequently Asked Questions

What makes slopmog different from the other tools?+
Every other tool on this list measures your visibility in AI answers. slopmog acts on it by seeding authentic, brand-relevant Reddit and YouTube comments, with you approving each one before it posts. Because Reddit is the most-cited source in AI Overviews and Perplexity, earning credible mentions there is a more direct lever than another dashboard.
What are LLM visibility tools?+
LLM visibility tools track whether and how AI engines like ChatGPT, Perplexity, and Google AI Overviews mention your brand when people ask relevant questions. The best LLM visibility checking tools report which prompts cite you, which engines surface you, and how your share of voice trends over time. Most are pure monitoring; a few are starting to add ways to act on what they find.
How do brands show up in ChatGPT answers?+
AI engines pull from the sources they trust, and those sources lean heavily on community content like Reddit, plus authoritative pages and reviews. So brands show up in ChatGPT by being mentioned credibly in the places these models read, which is exactly why tools for brand visibility in AI answers split into measuring those mentions and earning them.
Is seeding Reddit comments allowed?+
It sits in a genuine gray area you should take seriously. FTC endorsement guides require disclosing material connections, and Reddit's terms prohibit manipulation, so undisclosed brand promotion is astroturfing and can get accounts and posts removed by moderators. slopmog keeps a human in the loop on every comment, but the compliance and reputational risk is yours to manage.
Which LLM visibility tool has the best free entry point?+
For monitoring, Otterly.ai is the cheapest real start at $29/mo with a no-card 14-day trial, and Brand24 offers a 14-day trial too. slopmog has a free Reddit Comment Generator with no signup (five per hour) if you want to feel the action side before paying. Profound notably has no free trial.
Do I need more than one tool to track brand mentions in AI search?+
Often, yes. A measurement tool tells you where you stand in AI search visibility, but it cannot earn you citations on its own. Many teams pair a monitoring tool that fits their budget with a separate way to actually influence the source material AI engines read.
Which tool has the widest AI engine coverage?+
Among the measurement tools, Profound tracks 10+ engines at the enterprise level, and Scrunch AI covers 7 to 9 engines with the broadest standard-tier reach. Peec AI and Otterly.ai start with fewer base engines and charge add-on fees for more, so check the real per-engine cost before comparing sticker prices.
