9 Free AEO, GEO & Zero-Click Search Tools

An AI search visibility toolkit is a coordinated set of free utilities that audit how ChatGPT, Google AI Overviews, Perplexity, and Claude discover, index, and cite your brand — then tell you exactly what to fix. The nine tools below cover the full workflow: baseline your current mentions, monitor share of voice, expose the sub-queries AI engines silently run, generate machine-readable manifests, and quantify the pipeline value of every earned placement.

Key Takeaways

• Nine free tools, one workflow: audit → monitor → diagnose → generate → measure. Each tool is single-purpose and self-serve.
• Built for zero-click search: every tool ships copy-paste output — JSON-LD, llms.txt, H2 briefs, CSV — designed to be quoted directly by AI engines.
• No signup, no rate-limit tricks. Public tools return results in under 60 seconds and are usable from any device.
• Covers all four AI surfaces: ChatGPT, Google AI Overviews, Perplexity, and Claude — plus Grok on the audit and mention tools.
• Free forever. These are the same tools our team runs on every client engagement.

How to Use the Toolkit (In Order)

Run the tools sequentially the first time — each one produces an input the next one uses. After that, the monitoring tools become weekly habits and the generators become one-offs whenever you ship a new page or campaign.

1. Baseline — Am I in ChatGPT? + Brand Authority Audit
2. Monitor — LLM Mention Monitor (weekly)
3. Diagnose — AI Crawler Indexability Checker
4. Generate — llms.txt Generator, Query Fan-Out, People Also Ask Explorer
5. Measure — Earned Media ROI Calculator
6. Ask — Ask Smart Money Media for anything in between

1. Brand Authority Audit

What it does: Full-site AI visibility scan combining domain authority, backlink profile, schema coverage, AI Overview mentions, and live citation tests across ChatGPT, Perplexity, Claude, and Grok. Returns a downloadable PDF.

When to use it: Start here. This is the only tool that returns a single-number readiness score plus every underlying signal in one report.

Output: PDF report with 40+ signals, prioritized fix list, and citation screenshots.

2. Am I in ChatGPT?

What it does: 30-second check across ChatGPT, Claude, Perplexity, and Grok for a single query. Tells you whether the LLMs mention your brand, which competitors they surface instead, and what sources they cite.

When to use it: Anytime you want a fast pulse-check on a specific query without waiting for a full audit.

Output: Side-by-side answers from four LLMs with your brand highlighted.

3. LLM Mention Monitor

What it does: Aggregates mention volume for any domain across Google AI Overviews and ChatGPT answers. Returns total mentions, estimated AI search volume, top competing brands, and the source domains AI engines cite in your category.

When to use it: Weekly. This is the closest thing to a share-of-voice dashboard for AI search.

Output: Mention counts, competitor leaderboard, cited-source domain list.

4. AI Crawler Indexability Checker

What it does: Fetches your live robots.txt and tests 13 AI crawlers — GPTBot, ChatGPT-User, PerplexityBot, ClaudeBot, Google-Extended, CCBot, Applebot-Extended, Bytespider, and more — to reveal exactly who can and cannot index your site.

When to use it: Before every audit. If AI crawlers are blocked, nothing else in the toolkit will move the needle.

Output: 13-row pass/fail table plus the exact robots.txt lines causing any blocks.

5. llms.txt Generator

What it does: Generates a properly formatted llms.txt manifest for your domain in under a minute — recommended pages, brand description, and priority paths, ready to copy and ship to your root.

When to use it: Once at launch, then anytime you add a pillar page or restructure your site.

Output: Copy-paste llms.txt file with proper section headers and link syntax.

6. AI Search Query Fan-Out Tool

What it does: Enter a seed query and see the reformulations, related questions, comparisons, and entity expansions that ChatGPT, AI Overviews, and Perplexity silently generate behind the scenes. Ships with a ready-to-use H2 content brief.

When to use it: Before writing any pillar page, landing page, or long-form post. Fan-out queries are the atomic unit of AI search — cover them and you win the summary.

Output: Fan-out tree plus an H2-structured content brief.

7. People Also Ask Explorer

What it does: Predicts the People Also Ask questions Google shows for any query and the follow-ups that expand under each. Exports as CSV or drop-in FAQ JSON-LD schema.

When to use it: Every time you build an FAQ section. PAA questions are the highest-intent zero-click surface Google still gives you.

Output: PAA tree, CSV export, and copy-paste FAQPage schema.

8. Earned Media ROI Calculator

What it does: Live math for paid editorial placements, syndicated pickups, and earned coverage. Models CPM, CTR, lead conversion, and downstream revenue from a single placement or a full campaign.

When to use it: Before pitching a PR budget, before signing a syndication contract, and after every placement to close the loop on ROI.

Output: EMV, impressions, leads, and pipeline value with adjustable assumptions.

9. Ask Smart Money Media

What it does: Free AI chat trained on our full library of pillar guides, blog posts, glossary entries, and case studies. Ask any question about AEO, GEO, LLM SEO, PR strategy, earned media, or reputation and get cited answers.

When to use it: Instead of Googling a strategy question. Answers cite the underlying source so you can dig deeper.

Output: Cited conversational answer with clickable source links.

Which Tool Solves Which Job

The Zero-Click Publishing Workflow

Zero-click search rewards content that answers the question inside the SERP or LLM summary — no click required. That sounds like a threat until you realize the alternative is being invisible. Every tool above is engineered to feed that workflow:

• Fan-Out tells you the sub-queries the AI engine will decompose your topic into.
• People Also Ask Explorer gives you the exact FAQ block Google is already surfacing.
• llms.txt Generator hands the LLM a curated map of your best pages.
• AI Crawler Check confirms those pages are reachable in the first place.
• Mention Monitor tells you whether the summary now names you.

How This Stack Compares to Paid AEO Platforms

Enterprise platforms like Profound, Peec, and Otterly bundle similar signals into a single dashboard starting around $500-$3,000/month. That price tag is justified for large teams tracking hundreds of prompts across dozens of markets. For everyone else — solo operators, in-house SEOs, boutique agencies — the nine tools above cover the same jobs to be done at zero cost, at the price of running them yourself weekly instead of watching a dashboard.

What We Are Building Next

The toolkit is intentionally modular. We add a new tool whenever a repeatable client workflow surfaces that no free tool on the market handles well. Expect the roster to grow — bookmark the tools hub and check quarterly.
