This page is published by answer.show, an AI visibility product, and answer.show is one of the ten tools listed below. Tools are grouped by type and listed alphabetically, which is the only reason answer.show appears first in its group. It gets the same fields and the same scrutiny as every other entry.
Dedicated AI visibility trackers
answer.show
Runs a free, one-off AI visibility scan, then ongoing monitoring, checking whether an engine mentions, cites, or recommends a brand.
- Engines
- ChatGPT, Gemini, Perplexity
- Starting price
- Free scan; paid plans from $49/mo, as of October 2026
- Fits
- Teams who want to start with no budget and keep the same tool once they need ongoing monitoring
- Limitation
- Signup is a closed waitlist right now, so a new account needs an invitation, and the free scan covers three engines, leaving out Claude and Copilot
AthenaHQ

- Essential (free): ChatGPT, Perplexity, Google AI Overviews, Gemini, Copilot. Starter adds AI Mode, Claude, Grok, DeepSeek, Meta AI, Mistral.

- Free (300 credits, a $25 credit value); Starter $295/mo for 3,600 credits, as of October 2026
- Fits
- AEO and GEO specialist teams who want the broadest model coverage without a sales call
- Limitation
- The jump from the free tier straight to the $295/mo Starter plan is steep, with no disclosed mid-tier plan in between
Otterly.ai
Tracks a fixed prompt set on a recurring schedule, with unlimited seats on every plan.
- Engines
- Entry plan: ChatGPT, Google AI Overviews, Perplexity, Microsoft Copilot. Claude, Google AI Mode, and Gemini cost extra.

- Engines
- ChatGPT, Perplexity, Gemini
- Starting price
- Pricing on request. Plan prices are not published on the vendor pricing page as of October 2026.
- Fits
- SEO and content teams who want a no-commitment first read, via the free one-off GEO report, before talking to sales
- Limitation
- No plan price appears anywhere on the public site, so you cannot compare entry cost without contacting sales

- Engines
- Trial: ChatGPT, Gemini, Google AI Overviews. Enterprise adds Perplexity, Microsoft Copilot, DeepSeek, Claude, Exa Search, Google AI Mode.

- Fits
- Large enterprise teams with a Fortune-500-grade budget and sales cycle
- Limitation
- No public price exists for the real plan, and the free trial does not track Claude at all
Rankscale

- Engines
- OpenAI ChatGPT, Perplexity, Google AI Mode, Google AI Overviews, Gemini, DeepSeek, Mistral, Anthropic Claude, Microsoft Copilot, and more
- Starting price
- From $20/mo (Essentials, annual billing only); Pro $99/mo for 1,200 credits, up to 4,800 answers, 7-day free trial, as of October 2026
- Fits
- Agencies and multi-brand SEO teams who want transparent per-model unit economics
- Limitation
- The cheap Essentials tier is annual-billing only, so there's no month-to-month way to try it at that price
Scrunch
Bundles AI visibility tracking with a site audit and content delivery, calling itself an 'Agent Experience Platform' rather than just a tracker.
- Engines
- ChatGPT, Claude, Gemini, Perplexity, Google AI Mode, Google AI Overviews, Meta AI
- Starting price
- $250/mo billed annually, or $300/mo month-to-month (Starter, 350 custom + 1,000 industry prompts), 7-day free trial, as of October 2026
- Fits
- Teams who want to prove GEO impact on a defined prompt set before scaling to a bigger program
- Limitation
- Entry price is among the highest in this list, and the free trial is capped at 7 days rather than a persistent free tier

AI-mention tracking available as a standalone Custom Prompts product, or folded into an existing Ahrefs subscription.
- Engines
- ChatGPT, Gemini, Google AI Overviews, Google AI Mode, Microsoft Copilot, Perplexity

- SEOs and in-house teams who already pay for Ahrefs and want AI visibility folded into a tool they use daily
- Limitation
- The instant-read AI Visibility Index mode is a separate $199/mo product from the $50/mo Custom Prompts tier, so the real entry cost depends on which one you need

How to choose an LLM SEO tool
Buyers who have already tried two or three of these tools report the same complaints: scores with no explainable methodology, no path from a score to an actual fix, and non-determinism nobody warns you about. A repeat of the exact same prompt on the exact same engine returns the exact same brand list in under 1% of runs, so a single scan is a snapshot, not a trend line. Weigh a tool against these criteria before you pay for anything.
Engines covered
Match coverage to where your buyers actually ask questions. A tool that checks five engines is not more useful than one that checks three if the extra two are ones your audience rarely uses.
Prompts you control vs. a prebuilt database
Some tools run the exact prompts you write; others pull a read from a prebuilt database of prompts someone else chose. The database mode is faster to start but answers a question you didn't ask.
Repeated runs to handle answer variation
AI answers are probabilistic. A tool that scans once and reports a single score cannot tell drift from noise; one that re-runs on a schedule can.
Mention vs. citation vs. recommendation
Being mentioned, being cited as a source, and being the brand an engine actually recommends are three different outcomes. A tool that collapses all three into one score can call a competitor win a win for you.
Source and citation data
A tool that names which specific page got cited for which answer, on which engine, gives you something to act on. A single visibility number does not.
Price per prompt x engine x frequency
The sticker price is not the real cost. A 50-prompt plan checked daily on three engines is already roughly 4,500 AI answers a month; price out your actual usage, not the plan's headline number.
Spanish or LatAm coverage
Most large incumbents run English-only prompts against US competitor sets. If your buyers ask in Spanish, confirm the tool actually localizes the prompts rather than just translating the interface.
Frequently asked questions
What are LLM SEO tools?
LLM SEO tools check whether AI engines such as ChatGPT, Gemini, Perplexity, and Google AI Overviews mention, cite, or recommend a brand when someone asks a buying question, then track that over time. Most measure through recurring prompt runs rather than a fixed ranking position, since LLM answers vary from one run to the next.
Do I need an LLM SEO tool if I already use an SEO suite?
Several SEO suites, including Ahrefs, Semrush, and HubSpot, have added an AI visibility module to their existing plans, so if you already pay for one of those, check what it covers before buying a separate tool. A dedicated tracker is still worth it if you need more engines, repeatable prompt control, or deeper per-answer detail than the suite's module provides.
Are there free LLM SEO tools?
Yes. Several vendors in this list, including answer.show, Ahrefs, Semrush, and HubSpot, offer a free checker or a free one-time scan with no signup. Free checkers are useful as a first read, but they disagree with each other: an independent test of 37 free checkers by seoinformatica.com found scores for the same brands did not agree across tools, so treat any single free result as a snapshot, not ground truth.
How much do LLM SEO tools cost?
Entry paid plans in this list span $20 to $295 a month. The sticker price is a poor guide on its own: the real driver is prompts times engines times run frequency, so a cheap plan with daily runs across several engines can cost more in practice than an expensive plan run monthly.
