You published the page. It reads well, it ranks fine, and yet ChatGPT keeps quoting a competitor instead of you. If that stings, you are not alone, and it is fixable. What you need is a way to look at one URL and ask a simple question: is this page built to be extracted and cited by AI? An ai citability checker answers exactly that. Some run as an aeo browser extension you click while browsing. Others let you paste a URL and get a verdict. Either way, the goal is the same, to check if page is ai-ready before you move on to the next one.
Here is the honest part. This category is young. There is no single dedicated extension that does everything, so the smart move is to broaden your search to every on-page ai optimization tool that scores a single URL.
Take a breath. You only need to pick one to start, and this roundup will show you which.
How we chose these tools
A roundup is only as trustworthy as its criteria, so here are ours, stated up front. Every tool below had to earn its place against the same five tests.
- Single-page verdict. You give it one URL and get a citability score or diagnostic in one sitting.
- In-context check. The check happens on the page itself or through a paste-a-URL widget, not buried three clicks deep in a dashboard.
- Actionable fixes. The result tells you what to change on that page, structure, schema, answer formatting, or metadata.
- Grounded in real engine behavior. The signals reflect how ChatGPT, Perplexity, Gemini, Claude, and Google AI Mode actually parse and cite pages, not just classic on-page SEO.
- Free or trial entry. You can validate the tool before you commit a budget to it.
We ordered the list by how well each tool meets these criteria, not by how many features it lists. A citability audit tool that returns a clear verdict and a fix beats one with a longer feature page and no clear answer.
What we left out, on purpose: pure site-wide monitoring dashboards, content generators with no page-level diagnostic, and traditional SEO crawlers that never score for AI citability specifically.

1. DeepSmith
Best for: marketing leads who want to score a page, see what is missing, and ship the fix without leaving one platform.
Most tools stop at the diagnosis. DeepSmith closes the loop. It combines AI search analytics with content production, so the page-level check and the fix live in the same place. Paste a URL into the AI Visibility module, get a citability read, see which gaps are blocking the citation, and see which prompts would surface the page. Because the platform also tracks live citation rates across ChatGPT, Gemini, Perplexity, Claude, and Google AI Mode, that read is anchored to real engine behavior, not a rule of thumb.
The Pages view then ranks every URL by its share of your total citations and the prompts driving them. Competitor citations show which rival pages are winning the prompts you care about. When you decide to act, the writing pipeline builds citation-ready structure, schema, headings, metadata, and internal links in during creation, all grounded in your stored brand context so the fix still sounds like you.
Key features
- Page-level AEO audit with a citability read and a gap list
- Pages view ranking URLs by citation share and driving prompts
- Competitor citation tracking by page and prompt
- AEO formatting built into the writing pipeline
- Publishing to WordPress, Strapi, Webflow, and webhooks
Pricing starts at $99/mo for Pro (or $80/mo billed annually), rising through Grow at $199/mo and Scale at $399/mo, with custom Enterprise. There is a 7-day free trial and no annual lock-in.
Honest limitation: DeepSmith is not a standalone Chrome extension. The audit lives inside the web app, not a browser overlay.
2. Adobe AI Content Visibility Checker
Best for: a free, one-click read on whether a page is even bot-readable before you pay for anything.
This is the free Chrome extension built on top of Adobe LLM Optimizer, and it is the closest thing to a true aeo browser extension on the market today. It runs a URL through the kind of fetch a ChatGPT or Perplexity crawler would use, then returns a citation-readability percentage plus a side-by-side of what the agent sees versus what a human sees. That comparison is the aha moment.
Key features
- Citation-readability percentage per URL
- Agent-vs-human content comparison
- Detection of blocks that fail a bot fetch, like JS-only content or hidden tabs
- Recommendations to improve machine readability
Pricing: free, no account needed for the extension. Adobe LLM Optimizer is the paid enterprise escalation path.
Honest limitation: it diagnoses, it does not fix, track, or benchmark. Treat it as triage, not a program.
3. Troovue
Best for: teams that want a single-page diagnostic with a defensible scoring method behind it.
Troovue is the citability audit tool to reach for when you need to defend a score, because it treats citability as a function of three things, data points, structured markup, and answer-ready formatting. Its Visibility and Effort Index scores each page on those and applies a penalty when a page is thin on data points like statistics, dates, and named entities. The company publishes its own research, including a finding that AI systems cite an average of 4.7 unique domains per complex query. Key features
- VEI score per URL with a data-point count
- An answer-readiness penalty for thin pages
- Research-backed thresholds for length, data density, and markup
- Enterprise support for brand-wide programs
Pricing: not publicly listed. Enterprise-tier sales.
Honest limitation: the opaque pricing means you have to request a quote before you can weigh ROI.
4. Foglift
Best for: technical SEOs and developers who want an AI-readiness audit they can run as a repeatable process.
Foglift pairs AI search monitoring with a Technical Audit that returns an AI Readiness Score per URL, a prioritized fix list, and parse-ability checks against how engines actually crawl. It ships as a REST API and CLI, so you can wire the audit into your own workflow rather than clicking through a UI every time.
Key features
- AI Readiness Score per URL with prioritized technical fixes
- Crawl and parse-ability checks for SSR, schema, meta, and headings
- Daily monitoring of AI citations across engines
- API and CLI access for technical teams
Pricing: custom and sales-led, listed on G2 and Capterra without public tiers.
Honest limitation: it is heavier than most marketers need. The technical audit is the draw, so it fits dev and SEO teams more than content leads.
5. Otterly.AI
Best for: solo marketers and small teams who want budget-friendly monitoring with per-URL diagnostics.
Otterly tracks your presence across ChatGPT, Perplexity, Google AI Overviews, Gemini, and Claude, and shows which URLs are being cited and the prompts driving those citations. It will not rewrite the page, but it shows which of your pages are actually earning citations.
Key features
- Prompt-level citation and mention tracking
- Per-URL share-of-voice attribution with prompt source
- Outbound link monitoring
- Competitor benchmarking
Pricing: Lite at $29/mo for 15 prompts, Standard at $189/mo for 100 prompts, and Premium by sales.
Honest limitation: it is monitoring first. The page view shows you what is happening on a URL, but it does not fix the content.
6. Peec AI
Best for: mid-market teams that want prompt-level tracking with usable volume and per-URL insight.
Peec AI tracks brand mentions and citations across the major engines, with prompt-level data and per-page benchmarking against competitors. It also flags pages not yet cited and suggests where to act, which nudges it past pure reporting.
Key features
- Prompt tracking across ChatGPT, Perplexity, Claude, Gemini, and Copilot
- Brand mention analytics with sentiment
- Per-page benchmarking and competitive comparison
- Recommendations for prompts and pages not yet cited
Pricing: Starter from €89/mo, Growth at $399/mo for multi-LLM coverage, plus an agency tier.
Honest limitation: it is dashboard-centric. There is no overlay for grading a page instantly while you browse.
7. Profound
Best for: enterprise and larger mid-market teams that need rigorous, multi-engine citation intelligence.
Profound is built for enterprise AEO programs. It tracks how your brand and URLs surface in answer engines, categorizes every citation source, and offers watched-pages tracking plus analytics on how AI crawlers behave on your site. It is deep, and priced to match.
Key features
- Citation tracking across ChatGPT, Perplexity, Claude, Gemini, and Google AI Overviews
- Source Categorization into Owned, Competitor, Earned, PR, Social, and Institutional
- Watched Pages to follow a URL's citation changes over time
- Agent Analytics for AI bot crawling behavior
Pricing: custom and sales-led, not publicly disclosed.
Honest limitation: the enterprise price and onboarding are heavy if all you want is a quick single-page check.
8. Goodie
Best for: enterprise marketing teams running structured AEO programs at scale.
Goodie is an AI search analytics and optimization platform with page-level audits, semantic optimization suggestions, and competitor benchmarking on shared prompts. The semantic analysis is the differentiator, aligning your copy with what engines seem to prefer.
Key features
- AI visibility tracking across the major engines
- Page-level audit and optimization recommendations
- Competitor benchmarking on shared prompts
- Semantic analysis to align copy with engine preferences
Pricing: custom and sales-led. Public references point to Core around $250/mo and Agency Core around $500/mo, with custom Enterprise.
Honest limitation: it is enterprise-oriented, so lighter self-serve options are limited.
9. Rankscale
Best for: SEO and content teams comfortable with rank trackers who want an AI Overviews layer on top.
Rankscale focuses on AI Overviews and generative-engine ranking, refreshing prompt and URL visibility daily across engines. If your team already lives in a rank-tracking rhythm, it slots in naturally.
Key features
- AI Overviews tracking and ranking
- Daily refresh on prompt and URL visibility
- Competitor benchmarking
- Cross-engine coverage reporting
Pricing: an entry tier around $99/mo, with higher and enterprise tiers custom.
Honest limitation: it is stronger at ongoing tracking than at a true one-off single-page diagnostic.
10. LLMrefs
Best for: agencies and SEO teams that want repeatable prompt-based AEO audits at scale.
LLMrefs runs prompt-level audits and surfaces URL-level visibility trends, with exportable data for client reporting. If you run audits for many sites, the export step saves real hours.
Key features
- Prompt-level tracking across engines
- URL-level visibility trendlines
- Competitor benchmarks
- Exportable data for reports
Pricing: not publicly disclosed. Sales-led.
Honest limitation: it is built for recurring tracking, so it is less handy as a single-URL drop-in checker.
11. Scrunch AI
Best for: enterprise content and SEO teams that want automation acting on audit signals.
Scrunch pairs answer-engine monitoring with an agentic content engine that updates pages based on what the audit finds, whether that is schema, copy, or structure. The pitch is that the tool does not just tell you, it acts.
Key features
- AI answer-engine visibility across major platforms
- Page-level audit and recommendations
- Agentic updates to schema, copy, and structure
- Competitive benchmarking
Pricing: sales-led, with enterprise tiers and custom SLAs.
Honest limitation: the agentic automation is the whole point, so a lightweight drop-in check will feel like overkill here.
12. Frase
Best for: content teams that want an AI-readiness score inside the drafting workflow, not a separate audit.
Frase wraps content optimization with an AI Visibility score right in the editor, alongside topic and heading suggestions tied to AEO signals. You get the read while you write, which is a nice fit if you optimize as you draft.
Key features
- AI Visibility score for topics and URLs
- Content editor with topic and heading recommendations
- Competitor content analysis
- Google Search Console and CMS integrations
Pricing: plans from $39/mo (lower on annual), scaling by seats, articles, and tracked topics.
Honest limitation: it is optimizer-first. The AI score is a feature of the editor, not a standalone URL checker.
13. Surfer SEO
Best for: SEO teams already on Surfer who want to extend their optimization loop into AI engines.
Surfer's Content Editor has graded on-page SEO for years. Its AI Tracker layer adds visibility across AI search engines on top of that familiar workflow, so you keep your process and gain the AI signal.
Key features
- Content Editor scoring with NLP and topic suggestions
- AI Tracker for AI engine visibility
- SERP and content audits
- Topic and entity suggestions
Pricing: editor plans start around $79/mo on annual billing. AI Tracker pricing varies and is usually on higher tiers or an add-on.
Honest limitation: it is a content editor with an AEO add-on. The page-level AI score lives inside the editor, not a standalone checker.
14. Relixir
Best for: teams that want a generative-engine-optimization workflow with a built-in content agent.
Relixir is a GEO platform that combines AEO scoring with a content agent for on-brand creation and updates. It sits between diagnosis and production, closer to the do-it-for-me end.
Key features
- AEO page-level scoring
- Prompt and engine tracking
- A content agent for on-brand creation and updates
- Competitive benchmarking
Pricing: tiered plans with free trials. Specific pricing is not publicly disclosed.
Honest limitation: it is workflow-heavy. If you only want a quick score, the content-agent package is more than you need.
15. WordLift
Best for: brands that treat structured data and entities as the foundation of citability.
WordLift has long done schema markup and knowledge-graph work, and its AEO layer extends that into AI search visibility. There is a free AI audit for structured-data and entity checks, which is a low-risk way to start.
Key features
- Knowledge-graph-driven optimization
- Structured data and schema recommendations
- A free AI SEO audit for structured data and entities
- AI search visibility tracking
Pricing: tiered plans with custom enterprise options. The audit is free.
Honest limitation: it is heavy on schema and entities, so teams wanting a quick content score may find it slow to act on.
16. NeuronWriter
Best for: content teams that want NLP-based recommendations inside a brief and editor.
NeuronWriter blends NLP with generative AI, scoring pages for SEO and AI-readiness signals as you write. It is budget-friendly and a comfortable entry point if you are new to page scoring.
Key features
- Content editor with NLP-based scoring
- Per-page brief support
- AI content detection in the workflow
- Topic and entity recommendations
Pricing: entry plans from around $19/mo, with higher tiers adding seats and tracked topics.
Honest limitation: it is editor-first, not designed as a standalone drop-in URL checker.
17. LLMFriendly.ai
Best for: a quick, free URL drop-in check when you just want a fast read.
LLMFriendly.ai is a free audit-style tool that scores a URL for AI search readiness and returns recommendations. Paste a link, get a number and a short list.
Key features
- AI-friendliness score per URL
- Recommendations to improve AI discoverability
- A shareable quick report
Pricing: a free tier. Paid tiers may exist but are not publicly listed.
Honest limitation: the diagnostics are surface-level, so the depth of advice is thinner than a full AEO platform.
18. Schema Markup Validators
Best for: developers and SEOs validating the structured data that underpins citability.
The Schema.org Validator and Google Rich Results Test are free tools that check your markup against Schema.org and Google's rich-result specs. They surface the errors and warnings that quietly break how engines parse your page. They are not citability scorers, but they catch the structural mistakes that sink citability before it starts.
Key features
- Schema.org markup validation
- Rich-result eligibility testing against Google specs
- Errors and warnings per result type
- Free to use
Pricing: free.
Honest limitation: they validate structure only. They do not score your content for citability or signal quality.
How to choose the right one for you
Feeling a little overwhelmed by 18 options? That is normal. You do not pick a tool from a list, you pick it from your situation. Find yourself below.
You want free triage before spending a cent. Start with the Adobe AI Content Visibility Checker extension, the Schema.org Validator, the Google Rich Results Test, and LLMFriendly.ai. Together they let you check if page is ai-ready and answer "can AI even read this?" without a contract.
You own a technical or dev-led audit. Foglift gives you repeatable AI-readiness scoring with API and CLI access.

You optimize while you draft. Frase, Surfer SEO, and NeuronWriter put the AI score right inside the editor.
You run an enterprise program at scale. Profound, Goodie, Scrunch AI, and Relixir combine audits with tracking, benchmarking, and, in Scrunch's case, agentic fixes.

You want the page-level check and the fix in one place. That is where DeepSmith fits, when the audit needs to flow straight into on-brand production rather than stopping at a score.
