10 Best Free AI Visibility Tools in 2026

Before you pay for anything, it is worth knowing how much you can do for free. The answer: quite a lot on the input side — which AI bots crawl you, whether your content is AI-ready, how your pages score for citability. And almost nothing on the output side — whether AI actually cites you, who beats you, and what revenue it drives.

That split decides which free tool fits. Use the free tools to get AI-ready, then budget for a paid tracker when you need answer-side proof.

The 10 best free AI visibility tools at a glance

1. CiteTrack Free Tools + Chrome Extension — best free audit toolkit

CiteTrack's WordPress plugin is paid ($59–$249/yr). But alongside it, CiteTrack ships a suite of free standalone tools and a free Chrome extension that require no login, no account, and no API key.

The Chrome extension audits any page — not just WordPress — for SEO, AEO, and GEO readiness in one click. It scores the page, flags what is missing, and generates a prioritized mission board with copy-ready fix prompts. It works on competitor pages too, which makes it useful for spot checks and client audits.

The free web tools cover the diagnostic layer: an AI-Readiness Grader, an AI Crawlability Checker, a Schema Markup Generator, an llms.txt Generator, an llms.txt Validator, an AI Prompt-Pack Generator, an AI Crawler Log Analyzer, an AI Visibility Cost Calculator, and a Hidden AI Revenue Calculator. Ten tools, all free, no login.

Where free stops. The free tools audit and diagnose. They do not track citations, log crawlers continuously, or attribute revenue. That is the WordPress plugin's job, and it starts at $59/yr.

Best for. Anyone who wants to audit pages and diagnose AI-readiness gaps before committing to a paid tracker.

2. HubSpot AEO Grader — best free brand snapshot

HubSpot's AEO Grader is the most polished free brand-level check. Enter your company name, industry, and location, and it queries ChatGPT, Perplexity, and Gemini to score your brand across five dimensions: sentiment, presence quality, brand recognition, share of voice, and market position.

The output is a scored report with a total out of 100. Sentiment carries the most weight (40 points) because how AI describes you matters more than whether it mentions you.

Where free stops. It is a one-time snapshot, not ongoing monitoring. For continuous tracking, HubSpot sells HubSpot AEO at $50/mo. But the free grader is genuinely useful as a starting point — run it on yourself and three competitors.

Best for. A quick, no-cost read on how AI currently represents your brand.

3. AEO God Mode (free tier) — best free in-editor optimizer

AEO God Mode's free tier is a genuine optimizer, not a demo. It scores your content for citability in the Gutenberg sidebar as you write. Auto schema injection. llms.txt generation. Content-gap scanning. AI crawler allowlist.

The free tier does everything except track citations. That needs Pro (£9/mo), which queries four engines.

Where free stops. No citation verification. No revenue attribution. Four engines on Pro versus five on CiteTrack.

Best for. Writers who want real-time optimization feedback on every post without paying anything.

4. Answer Engine Optimization plugin (wp.org) — best free schema coverage

The most feature-complete free AEO plugin on wordpress.org. No Pro tier. No feature locks. No upsell prompts.

40+ Schema.org types. AEO Score 0-100 per post. AI FAQ generator. llms.txt. Speakable schema. WooCommerce product schema. Multi-location LocalBusiness. AI features (rewriting, briefs) use your own API keys optionally.

Where free stops. No citation verification. No crawler analytics dashboard. You optimize and hope.

Best for. Sites that want the deepest free schema and AEO scoring without any paid commitment.

5. VigIA — best free AI-readiness scorer

If you want one genuinely free tool that does the most on the input side, VigIA is it. A WordPress plugin from Fernando Tellado's AyudaWP project, mature and actively maintained.

Crawler analytics across 55+ AI bots with a real dashboard. A 100-point AI-readiness analyzer that grades any page across five categories and hands back a fix list. PHP-level and robots.txt blocking with compliance monitoring. An llms.txt generator. JSON-LD output. An Abilities API for automation.

Where free stops. It measures readiness, not results. A 100/100 means your page is easy for AI to parse, not that any engine cites you.

Best for. WordPress site owners who want to get AI-ready and watch crawlers without paying anything.

6. GetCited — best free content checklist

GetCited scores each post 0-100 for citability based on the traits AI answers reward: a clear opening summary, clean headings, FAQ sections, depth, and author attribution. It pairs that with crawler controls for 31 bots, an llms.txt generator, and AI-optimized schema.

Where free stops. The score predicts from your own content. It never queries ChatGPT or Perplexity, so it cannot confirm a real citation.

Best for. A free, per-post checklist to make your writing more quotable.

7. LLM Bot Tracker — best free zero-config logger

Install it and it logs 59 AI bots immediately. Filtering, a 30-day trend chart, a top-bots leaderboard, CSV export. An AI Blind Spots view flags pages AI has not crawled yet.

Genuinely free with no upsell. One caveat: last updated roughly eight months ago.

Where free stops. Logging only. No robots.txt control, no readiness depth, no citations, no revenue.

Best for. The broadest bot list and instant data, for free.

8. Aiso — best free read on crawler intent

The newest free logger. It reframes crawler data as marketing impressions, with a standout metric: "chat impressions" — fetches that happen the moment an AI assistant is answering someone. Breaks activity down by platform, crawler, purpose (training vs live answer vs search), and page.

Where free stops. Brand new with very few installs. Infers intent but never confirms a citation.

Best for. The sharpest free read on why bots visit. Test it before you trust it.

9. Known Agents — best free bot control with a citation signal

Known Agents (formerly Dark Visitors) has a free tier that pairs realtime bot analytics and category-based robots.txt control with a referral-side citation signal — showing which pages LLMs recommend and how many humans click through. You can replay an individual agent's path through your site.

Where free stops. Event caps run out on busy sites. Citation tracking is referral-based and backward-looking, not prompt-based.

Best for. Free bot control plus a referral read on citations. Mind the event caps.

10. Otterly.ai — best free trial of paid monitoring

Otterly belongs here with an asterisk. It is not permanently free. But it offers a free trial of real answer-side monitoring — ChatGPT, Perplexity, Copilot, and Google AI Overviews — which the genuinely free tools cannot do.

Where free stops. It is a trial, not a free plan. After it, entry is $25/mo annual. See Otterly pricing.

Best for. Testing real citation monitoring for free before committing to a paid tool.

How to choose

The honest takeaway: free is excellent for the input side. No free tool measures whether AI actually cites you. When that becomes the question, the cheapest real answer is CiteTrack AI at $59/yr — less than two months of any monthly tool.
