Semrush and Writesonic track only three to four engines on their entry plans, so check coverage before you buy.
LLM SEO means optimizing for the models that answer your buyers: ChatGPT, Perplexity, Gemini, Claude and the rest. The job mixes tracking, which models mention you, with fixing, which pages and facts earn citations. This guide ranks the 8 best LLM SEO tools in 2026 by the features that improve and measure LLM visibility, from engine coverage to content actions.
Profound is an enterprise AI visibility platform that tracks how brands appear in answers from ChatGPT, Perplexity, Gemini, Google AI Mode, AI Overviews, Copilot, DeepSeek, Claude and Exa. It pairs that tracking with AI agents that draft marketing work and a Context Manager that stores brand facts for those agents.
Profound covers the widest engine set in this list, which suits teams that want one view of LLM visibility instead of a separate tool per engine. FactCheck flags claims AI engines make about your brand that do not match your facts. The catch is access: there is no self-serve paid plan, and pricing is custom, so a small team cannot simply sign up and start tracking.
What we like
Tracks up to 9 answer engines, including ChatGPT, Perplexity and Gemini (Nov 2026).
Agent Analytics shows how AI crawlers and agents use your site.
Unlimited seats on paid plans, with SSO and SOC 2 compliance.
Watch out for
No public prices; paid plans need a sales conversation.
The free trial runs 50 fixed prompts a day for 7 days only.
Small teams will likely find it priced above their budget.
Goodie AI runs the whole loop: it monitors where your brand appears in AI answers, diagnoses the gaps, takes action through content and technical fixes, and measures the revenue impact. Every plan includes the optimization layer, so you pay for outcomes, not just a dashboard.
Goodie AI tracks five engines on Core, eight on Pro and up to 14 on Enterprise. Its prompt research finds high-intent questions in your category, and the agent drafts content to win them. The catch is the price and the limits: $295 a month buys one brand in two countries, and API access waits for Enterprise.
What we like
Core covers 110 prompts across 5 engines with 50 optimization actions a month (Nov 2026).
Every plan includes the full action layer, not just monitoring.
Revenue attribution links AI visibility to visits and sales.
Watch out for
Core costs $295 a month, the joint-highest entry here.
API access is reserved for Enterprise.
Core tracks 1 brand in 2 countries and 2 languages only.
AthenaHQ tracks brand visibility, mentions, citations, sentiment and share of voice across AI engines, then gives you content agents that act on the findings. The free Essential plan covers five engines, while Starter adds six more models and unlimited prompts.
AthenaHQ tracks 11 models on Starter, the widest paid coverage in this list. Prompt volume estimates show how often people ask each question, so you can focus on prompts with real demand. The catch is the credit meter: some engines cost five credits per answer, so 3,600 credits a month can run out faster than the number suggests.
What we like
The free Essential plan covers 300 credits across 5 engines (Nov 2026).
Starter tracks 11 models with unlimited prompts and competitors.
Unlimited seats and role-based access come with every plan.
Watch out for
Starter costs $295 a month, a big jump from the free plan.
Credit use is hard to forecast: some engines cost 5 credits per answer.
Scrunch AI monitors how AI engines mention your brand, then analyzes the results with site audits, funnel stages and query fan-out data. It suits teams that want tracking plus on-page optimization in the same subscription.
Scrunch AI tracks four LLMs on Core and nine on Enterprise, including Claude, Gemini, Meta AI and Grok. Its AI agent and bot traffic view shows which engines visit your site. The catch is the price: $250 a month is the entry point, and API access waits for Enterprise.
What we like
Core covers 125 prompts, 5,000 responses a month and 5 site audits (Nov 2026).
Tracks ChatGPT, Perplexity, Google AI Overviews and Copilot on Core.
Sentiment analysis and insights come with every plan.
Watch out for
Core costs $250 a month, which is steep for a small team.
API access is limited to Enterprise.
Core allows only 1 brand workspace and 5 user licences.
Peec AI is an AI search analytics platform that runs your prompts daily through the models you pick and reports visibility, position, sentiment and share of voice against competitors. It adds prompt suggestions, gap analysis and fact-checking, which compares AI claims about your brand with facts you set.
Peec AI tracks up to six models on self-serve plans and up to 13 on Enterprise, with prompt volume scores that show which questions carry real demand. Fact-checking compares AI claims with your brand facts. The catch is the model cap: self-serve plans track only three models, and adding a fourth costs extra each month.
What we like
Starter covers 50 prompts with daily tracking and unlimited users (Nov 2026).
Prompt suggestions and fact-checking point to gaps worth fixing.
Looker Studio integration on Advanced supports client reporting.
Watch out for
Self-serve plans track only 3 of 6 models; extra models cost $30 to $140 a month each.
No built-in content creation; it reports gaps but does not draft the fix.

Writesonic tracks how AI engines mention your brand, then helps you fix the gaps with AI-written content, optimization and audits in the same subscription. Its Action Center ranks opportunities by visibility and citation impact.
Writesonic tracks ChatGPT, Gemini and AI Overviews on self-serve plans, with sentiment analysis from Growth up. Enterprise adds all ten platforms, including Perplexity and Claude. The catch is engine coverage: Starter tracks three engines, and Perplexity, Claude, Copilot and Grok wait for the custom-priced Enterprise plan.
What we like
Starter costs $79 a month billed annually with 50 tracked prompts (Nov 2026).
Every plan includes the AI Article Writer, site audits and GEO tracking.
The free trial needs no credit card.
Watch out for
Starter tracks only ChatGPT, Gemini and AI Overviews; Perplexity waits for Enterprise.
Only 1 user and 1 project on Starter; extra users cost $50 a month each.
Annual billing saves 20%, but you pay 12 months upfront.
Otterly.AI tracks brand visibility, sentiment and citation sources across ChatGPT, Google AI Overviews, Perplexity and Microsoft Copilot, with daily refreshes. It adds brand profiling, a prompt research tool and AI search optimization recommendations that point to pages worth fixing.
Otterly.AI tracks four engines on the base price and adds Claude, Gemini and AI Mode as paid add-ons. Its GEO audit checks pages for the signals AI engines use when they pick sources. The catch is the prompt cap: Lite covers 15 prompts, and the next tier costs more than six times as much.
What we like
Lite starts at $29 a month with 15 prompts across 4 engines (Nov 2026).
Unlimited team members and unlimited brands and competitors on every plan.
Agency Partner status adds extra prompts and pitch workspaces on Standard and Premium.
Watch out for
Lite tracks only 15 prompts, which runs out fast for a real content plan.
Claude, Gemini and Google AI Mode cost extra as add-ons.
Standard jumps to $189 a month, a steep step from Lite.
Semrush is the best-known SEO suite in this list, and its AI Visibility Toolkit brings brand mentions, citations and share of voice into the same dashboard as keyword and audit data. The free account opens a sample of the toolkit with 10 reports a day.
Semrush tracks ChatGPT, Gemini, AI Overviews and AI Mode daily, with Perplexity in weekly Brand Performance reports. Its prompt database of 317 million prompts helps teams find questions worth tracking. The catch is the add-on math: the Pro plan at $139.95 a month does not include prompt tracking, so AI visibility costs $99 a month per domain on top.
What we like
The AI Visibility Toolkit costs $99 a month per domain with 25 prompts a day (Nov 2026).
The free account gives 10 reports a day across keyword, audit and backlink tools.
Prompt Research draws on a database of 317 million prompts.
Watch out for
The $139.95 Pro SEO plan has no prompt-tracking quota; AI tracking is a separate $99 toolkit.
Perplexity appears only in weekly Brand Performance reports, not daily tracking.
Extra domains cost $99 a month each, and extra users need their own licence.
Sources used: vendor pricing pages, vendor product pages and vendor help pages, checked Nov 2026.
