Best Free AEO Audit Tools to Check Your AI Citability

You searched your own brand in ChatGPT last week, and a competitor came up instead of you. Now you want to know why, and whether AI engines can even see your site. Good news: you do not need a budget or a sales call to find out. A free AEO audit tool can tell you, in under a minute, whether ChatGPT, Perplexity, Gemini, Claude, and Google AI Mode can crawl, parse, and cite your pages.

This guide is a shortlist of the best ones. Every tool here runs a one-shot diagnostic on your own domain and hands back a score or a yes-no answer. No credit card, no long setup, no dashboard to learn. You run it, you read the report, you know where you stand.

Take a breath. This is the easy part, and you can do all of it today.

How we picked these tools

A roundup is only useful if you know how it was built. Here are the five rules every tool on this list had to meet.

• Truly free to run a full scan. No credit card to see real output. A trial counts only if it returns a working diagnostic, not a teaser.
• Returns a concrete result. A citability, readiness, or GEO score, or a clear yes-no on whether AI can cite you.
• Covers the engines that matter, or the prerequisites for them. Either it queries ChatGPT, Perplexity, Gemini, Claude, and Google AI Overview, or it checks the technical basics that make citation possible: bot access, schema, sitemap, content structure.
• Does not hide the data behind a paywall. You see the actual findings, not a locked preview.
• Active and updated in 2026. No abandoned tools.

One thing to keep straight before you start. A free audit is a snapshot. It tells you where you stand today. Ongoing monitoring, tracking how often each engine cites you over weeks and months, is a separate job. Most of the confusion in this space comes from tools that call themselves free but mean free audit and paid monitoring. We flag that for every tool below.

The tools at a glance

1. DeepSmith

Best for: Marketing leads who want a real audit on their own brand and the citation-ready article to fix what it finds, in the same place.

DeepSmith is one platform for AI search analytics and content production. It tracks how AI engines answer questions about your brand, measuring mention rate, citation rate, and share of voice across ChatGPT, Perplexity, Gemini, Claude, and Google AI Mode, with coverage rising by plan tier. The same data feeds Content Studio, which produces on-brand, publish-ready articles to close the gaps the audit surfaces. Most tools on this list tell you what is wrong. This one shows you and then helps you fix it.

The audit lives inside a 7-day free trial with real data and real drafts before you pay. Signup to a working workspace takes minutes, with your brand brief, competitors, and starter tracking prompts populated before payment. No credit card, no long-term contracts, no cancellation fees.

Key features for a first audit:

• Mention rate, citation rate, and share of voice, with a per-platform breakdown and a competitor leaderboard.
• A Prompts view showing per-prompt mention and citation rates, plus Discover Prompts, which generates the questions you should be tracking from your product and persona.
• A Pages view showing which of your pages AI actually cites and each page's share of your total citations.
• A Sitemap module that classifies every existing page by topic, type, angle, and buyer stage.

Honest limitation: It is a paid platform after the 7-day trial, so you cannot stay free forever. The trial is a real workspace with real data, but it is a window, not a permanent free tier. It tracks the five named engines only, and the Pro plan covers ChatGPT alone.

2. Foglift

Best for: The fastest no-friction scan with the broadest category coverage and no email gate.

Foglift's free tier is a genuine unlimited Technical Audit. Paste any URL and it scores you across six categories, SEO, GEO, AEO, performance, security, and accessibility, in roughly 30 seconds, with no signup. If you want one number that captures your whole technical picture, this is the quickest way to get it. Paid plans add scheduled monitoring and a content-brief engine, but the audit itself costs nothing.

Key features:

• A unified six-category score with a severity-ranked issue list and plain-English fixes.
• AI crawler analytics showing which bots, like GPTBot and ClaudeBot, actually visit your URLs.
• Developer hooks: a REST API, a CLI, and Model Context Protocol support for CI/CD.

Honest limitation: The free promise applies to Technical Audits only. Continuous AI Visibility monitoring and historical trends need a paid plan, and the free monitor is weekly and limited to Google AI Overview.

3. Troovue

Best for: Marketers who want to know whether AI can cite them at all, rather than tracking rankings or traffic.

Troovue calls itself an evidence-based diagnostic engine for search and AI visibility. Instead of counting mentions over time, it asks whether your site is structurally eligible to be referenced and what is blocking that. The public library holds more than 30 free calculators, graders, and checkers, including an AI Visibility Score Calculator and an AI Search Readiness Grader that returns a letter grade. That grader is an easy first move if you want a plain, honest read on your standing.

Key features:

• Eligibility diagnostics rather than rankings data.
• A free AI Visibility Score Calculator and an AI Search Readiness Grader.
• A symptom-to-fix troubleshooting workflow.

Honest limitation: The free tools are calculators and graders, not the full end-to-end audit. Troovue's paid audit pricing is not published, so you cannot compare plans without a conversation.

4. Geoptie

Best for: Teams who want one weighted GEO readiness score mapped to the six industry dimensions.

Geoptie's free GEO audit scores any URL against six weighted dimensions and returns an actionable report in under a minute, no signup. The weights are explicit and add up to 100 percent: citation readiness (25%), answer alignment (20%), content authority signals (20%), knowledge graph integration (15%), technical AI accessibility (10%), and competitive differentiation (10%). If you have wondered how the industry actually defines GEO readiness, this framework is a clear place to see it.

Key features:

• A six-dimension weighted GEO score with tier labels like AI-Optimized or Not AI-Optimized.
• Tailored recommendations rather than template matching.
• Fast repeat audits through caching.

Honest limitation: This is a GEO audit, not a traditional SEO one. It does not measure keywords, backlinks, or page speed. Trend tracking and alerts require the paid plan, which starts at $41/mo.

5. LLM Clicks AI Readiness Analyzer

Best for: B2B SaaS marketers checking whether GPTBot, ClaudeBot, and PerplexityBot can actually reach and read their site.

If you want an AI readiness checker free of any signup, this is a strong pick. LLM Clicks runs an instant 9-point technical audit that verifies whether your architecture is machine-readable by LLMs. It looks at agent crawlability through robots.txt and response headers, semantic payload extraction, entity detection, JSON-LD schema, and whether your key answers sit up front in under 100 words.

Key features:

• An AI Readiness Score from 0 to 100.
• A 9-point prioritized action plan.
• An Architecture Gap Finder that flags missing schema and weak page structure.
• A shareable branded PDF report for your stakeholders.

Honest limitation: It focuses only on technical LLM-readability. It does not measure your actual mention or citation rates in real engine responses, so that next step is on you.

6. AI Rank Lab

Best for: Marketers who want SEO, AEO, and GEO in one audit, plus Core Web Vitals and AI bot tracking.

AI Rank Lab audits SEO, AEO, and GEO together, alongside brand visibility, page speed, and AI bot visits. The free tier, gated by a no-card signup, gives you 100 credits, enough for one full Website SEO, AEO, and GEO audit, one brand visibility prompt run, and a handful of keyword searches. You get a comprehensive PDF report by email.

Key features:

• 100-plus ranking factors across SEO, AEO, and GEO.
• A brand visibility prompt run against ChatGPT, Gemini, Perplexity, and Claude.
• AI crawler visit tracking and Core Web Vitals.

Honest limitation: The free tier is thin and resets monthly, and credits do not roll over. Ongoing use runs from $69/mo. The credit model can also make it unclear what counts as one audit versus one prompt.

7. seoscore.tools

Best for: Marketers who want the most checks and downloadable reports, with no signup.

This is a three-in-one SEO, AEO, and GEO scanner. It runs more than 260 technical checks in under 8 seconds and returns a separate score for each layer. You can scan a single page, run a multi-page crawl in beta, or scan site-wide, then export the findings as PDF or CSV. If you like to hand a report to your team, the export makes that simple.

Key features:

• 260-plus checks per scan across SEO, AEO, and GEO.
• Engine coverage in scope for Google, ChatGPT, Perplexity, AI Overview, Bing Copilot, and Claude.
• A prioritized red-items fix list.

Honest limitation: A breadth scan cannot fully replace a manual review. Average scores across all users run low (52 for SEO, 28 for AEO, 13 for GEO), so read your number as a percentile, not a verdict. A 13 is a normal starting point, not a disaster.

8. Digital Success Free GEO Audit Tool

Best for: Marketers who want a real AI-simulated citation check, not just a static schema scan.

Most scanners inspect your site. This one queries an AI model. Digital Success runs live GPT-4o queries with web search to simulate how AI engines currently treat your brand, then returns a GEO Visibility Score from 0 to 100, a schema health audit, and a competitor citation analysis, all in under 60 seconds. No signup, no API key. It is the closest thing on this list to watching an engine answer a question about you.

Key features:

• A real-time citation check powered by GPT-4o with live web search.
• A JSON-LD schema audit.
• A competitor citation analysis showing who currently wins your target keywords.

Honest limitation: Because the score comes from live model calls, it is slightly noisy between runs. Re-run it a couple of times and watch the trend rather than fixating on a single number.

9. RankPrompt Free AI Readiness Checker

Best for: A quick sanity check on whether AI bots can reach and parse your site.

RankPrompt's checker is a single-shot diagnostic. Give it your URL and it audits robots.txt AI bot access, Schema.org markup, meta tags, Open Graph, your SSL certificate, and sitemap coverage, then returns an overall readiness score and an issue list. This is the tool to reach for when you just want a fast AI readiness checker free of any commitment, before deciding whether to go deeper.

Key features:

• Several checks in one shot: AI bot access, schema, meta tags, Open Graph, SSL, and sitemap.
• Reference robots.txt checks for GPTBot, ClaudeBot, and PerplexityBot.
• Output structured as an issue list, not just a number.

Honest limitation: The free page is a fast diagnostic, not a full site audit. Treat it as a starting point, not the whole picture.

10. Maciej Turek AEO Lite

Best for: A single-page AEO diagnosis in a clear entity, evidence, experience frame.

This is a lightweight AEO checker from an independent consultant. Drop in a page and it returns an instant Answer-Engine score, split into three sub-scores for entity, evidence, and experience, with a tailored fix plan sent by email. If the three-part breakdown clicks for you, it is a genuinely useful way to see what a single page is missing.

Key features:

• An instant Answer-Engine score.
• Entity, evidence, and experience sub-scores.
• Single-page analysis with no login.

Honest limitation: It analyzes one page, not your whole site. The maintainer is an independent consultant, so the tool is not bundled with a larger product and its long-term runway depends on one person's priorities.

11. Agenxus AEO Audit Chrome Extension

Best for: Scoring any page you are looking at, in the moment, while you browse.

This free Chrome extension runs an AEO scan on whatever page is open, yours or a competitor's, and returns a score in under two seconds. It validates JSON-LD schema for AI grounding and checks content alignment for word count, hierarchy, and depth. Because the analysis runs locally in the browser, no page data is sent to a remote server.

Key features:

• Under-two-second scoring on the active tab.
• JSON-LD schema validation tuned for AI Overview grounding.
• Content alignment analysis and question-style heading detection.

Honest limitation: You get 10 scans per day, a hard cap. It is single-page only, with no site-wide audit, no history, and no competitor benchmarking inside the extension.

12. PromptRush Free AI Visibility Checker

Best for: A baseline read on how your brand is mentioned across five AI engines, plus who is beating you.

PromptRush scans ChatGPT, Gemini, Perplexity, Google AI Overviews, and Google AI Mode to detect mentions and citations of your brand, then returns a competitor comparison, citation source URLs, and word-for-word response excerpts. It takes about five minutes and gives you a real starting picture of your standing. If you want a free AI citability check that shows the actual engine answers, this delivers that.

Key features:

• A five-engine mention report with a 0 to 100 visibility score.
• Competitor share-of-voice ranking for your category.
• Citation source domains and exact response excerpts.

Honest limitation: The free tier is a baseline snapshot. Daily monitoring and large prompt libraries need a paid plan, and the roughly five-minute report is slower than the instant scanners above.

How to choose the right one for you

Twelve tools is a lot when you just want to start. So do not try them all. Pick the one that matches what you actually want to see, run it today, and move on.

• You want a real audit on your brand and the article to close the gaps. Start with DeepSmith's free trial.
• You want a fast, broad scan with no signup. Run Foglift.
• You want structural eligibility, not rankings. Use Troovue.
• You want one weighted GEO score. Use Geoptie's free GEO audit.
• You want to know if GPTBot and friends can crawl you. Run LLM Clicks.
• You want breadth and an exportable report. Use seoscore.tools.
• You want to watch an AI actually answer about you. Run Digital Success.
• You want a 30-second technical sanity check. Use RankPrompt.
• You want a single-page entity, evidence, experience read. Use Maciej Turek's AEO Lite.
• You want to score pages as you browse. Add the Agenxus extension.
• You want a mention baseline across five engines. Run PromptRush.

Here is the honest truth about all of these. A free audit tells you where you stand right now. It does not tell you what changes as you publish, and it does not fix anything. The score is the starting line, not the finish.

That is the gap DeepSmith is built to close. During the 7-day free trial you get the real audit and the ongoing tracking on real data, plus the production engine that turns each gap into a publish-ready, on-brand article. If you want the diagnosis and the fix in one place instead of a scanner in one tab and a writer in another, start your free DeepSmith trial and run your first audit today.

You do not need a bigger team or a bigger budget to begin. You need one scan and one next step.
