Free AI Visibility Scanners: 12 Tools That Check Your Brand on ChatGPT, Gemini & Perplexity

- Truly free tools exist — but most have limitations: small query samples, single-platform coverage, or paywalled deeper insights.
- The "free" label is doing a lot of work in this category. Some tools are free forever, some are free trials, some are free betas with usage limits. We separate them honestly below.
- No free tool gives you statistical reliability. AI responses are nondeterministic — running 5 queries once is directionally useful, not definitive.
- Most paid tools start at $49–$99/month and climb fast. Enterprise platforms can run $500–$1,500+ per month.
- Different tools optimize for different metrics — mention rate, citation rate, sentiment, source mapping, or hallucination detection. Pick based on what problem you are actually trying to solve.
The AI visibility category went from "doesn't exist" to "saturated with tools" in roughly 18 months. As of mid-2026, there are at least 30 platforms claiming to track how ChatGPT, Gemini, Perplexity, and Google AI Overviews talk about your brand. Most of them charge between $49 and $499 per month. A handful are genuinely free. A few sit in the awkward middle — free trials, limited beta access, or "free tool plus paid upgrade" models that obscure what you actually get.
This guide covers 12 of the most credible options across the full pricing spectrum. The goal is honest comparison, not a sales pitch. We score each tool on what it actually delivers, what it costs, and where it falls short — including DirJournal's own free AI Visibility Checker, which sits in the same "limited free runs" category as several competitors.
Before we dive in, a quick disclosure: DirJournal makes one of the tools listed below. We're including it because excluding it would be dishonest, but we're scoring it the same way we score everyone else. If you think we're being too kind to ourselves, the comparison tables make the trade-offs explicit. Skip to whichever section is most relevant to your budget.
📐 How We Evaluated Each Tool
Every tool below was assessed on six dimensions:
- What's actually free — Distinguishing genuinely free tools from "free trial" or "free preview with paywalled insights"
- AI engine coverage — How many platforms are scanned (ChatGPT, Gemini, Perplexity, Claude, Copilot, Google AI Overviews, etc.)
- Query depth — How many prompts per scan, and whether they are buyer-style queries or generic brand mentions
- Output quality — Score? Source citations? Competitor benchmarking? Actual AI responses shown?
- Friction — Signup required? Credit card? Email verification? Usage limits?
- Honesty about limits — Tools that admit what they cannot do score higher than tools that overstate their capabilities
Part 1 · Truly Free, no Signup Required The Lowest Friction Option
| # | Tool | Coverage | Signup | Output |
|---|---|---|---|---|
| 1 | Ahrefs Brand Radar (free) | ChatGPT, Gemini, Perplexity, Copilot, Google AI Overviews, AI Mode | None | Top 5 results per section, search-backed prompts |
| 2 | Semrush AI Search Visibility Checker | ChatGPT, Gemini, Google AI Overviews | None | Visibility score, prompt analysis, competitive view |
| 3 | SUSO Digital AI Visibility Checker | ChatGPT, Gemini, Perplexity, Grok | None | 0–100 score across 6 categories, 100+ signals |
| 4 | Zerply AI Visibility Checker | ChatGPT, Claude, Perplexity, Gemini | None | Sentiment, competitor rankings, actual AI responses |
What You Actually Need to Know
Ahrefs Brand Radar (free version) — The most credible free tool in this category, mainly because it's backed by Ahrefs' actual prompt database derived from real Google search behavior (rather than synthetic queries that competitors invent). Covers six AI platforms in a single check. The catch: you only see a "limited preview" of the top 5 results per section. The full data lives behind their paid Brand Radar product. Still the best free starting point if you want directionally accurate data with zero friction.
Semrush AI Search Visibility Checker — Free, no signup, decent breadth. Covers ChatGPT, Gemini, and Google AI Overviews (notably missing Perplexity in the free version). The output includes a visibility score, prompt-level breakdown, and a "where competitors appear and you don't" view. Semrush's paid AI Visibility Toolkit is $99/month as an add-on requiring a base Semrush plan ($139.95+/month) — total minimum around $239/month — which is why the free tool exists as a top-of-funnel hook.
SUSO Digital AI Visibility Checker — Underrated. 100% free, no signup, no paywall. Their proprietary algorithm evaluates 100+ signals across six categories: brand awareness, sentiment, training data presence, prompt visibility, technical structure, and off-site signals. Outputs a 1-100 score with category breakdowns. The trade-off is the data quality varies by industry — well-covered industries (SaaS, consumer brands) get more useful results than narrow B2B niches.
Zerply AI Visibility Checker — Genuinely free, no signup, unlimited reports. Shows actual AI responses (not just counts), sentiment scoring, and auto-detected competitor rankings. The paid product (Zerply Pro) adds continuous monitoring and an AI assistant. Worth bookmarking specifically because it shows you the verbatim language each AI uses to describe your brand — useful intelligence for refining your messaging.
Part 2 · Free With Signup A Small Friction Trade-Off for More Data
| # | Tool | Coverage | What you get |
|---|---|---|---|
| 5 | HubSpot AEO Grader | ChatGPT, Perplexity, Gemini | 5-dimension scored report, market positioning analysis |
| 6 | OpenLens | ChatGPT, Claude, Google AI, Perplexity, DeepSeek | Sentiment, attributes, source citations, competitor comparison |
| 7 | Ubersuggest AI Brand Visibility | Major AI platforms | Free brand visibility report (Ubersuggest account) |
What You Actually Need to Know
HubSpot AEO Grader — Probably the most polished free tool in this list, which makes sense given HubSpot's resources. Evaluates your brand across five dimensions (sentiment, presence quality, brand recognition, share of voice, market position) using deterministic scoring with retry logic. You enter company name, location, industry, and product/service, and it queries ChatGPT, Perplexity, and Gemini. Requires a form submission to access full results, which means HubSpot will market to you afterward — that's the price. The depth of analysis is genuinely good, especially the sentiment dimension which most competing tools handle superficially.
OpenLens — Launched in March 2026 as a fully free platform. Covers five AI assistants (ChatGPT, Claude, Google AI, Perplexity, DeepSeek). The pitch is comprehensive monitoring at no cost — sentiment analysis, attribute scores, source citations, and competitive benchmarking. Newer entrant so the long-term sustainability of the free model is unclear, but worth using while it lasts. Strong choice if you specifically want Claude or DeepSeek coverage, which several competing tools skip.
Ubersuggest AI Brand Visibility — Available inside the Ubersuggest dashboard. Free tier exists but you'll be nudged toward paid Ubersuggest plans. Less specialized than dedicated AI visibility tools, more useful if you're already a Neil Patel ecosystem user and want one less tab to manage.
Part 3 · Free Beta or Limited Free Runs Free With Usage Caps
| # | Tool | Free allowance | Coverage | Best for |
|---|---|---|---|---|
| 8 | DirJournal AI Visibility Checker | 1 scan per email per 7 days | ChatGPT, Perplexity, Google AI Overviews, Gemini | Real buyer-style queries + source intelligence |
| 9 | LLMClicks.ai | 50 free credits, no card required | ChatGPT, Perplexity, Claude, Gemini, Copilot | Hallucination detection (its core differentiator) |
| 10 | Visiblie | Free trial (limited) | Up to 8 models on Enterprise; ChatGPT only on Starter | Multi-model coverage, accuracy tracking |
What You Actually Need to Know
DirJournal AI Visibility Checker — Yes, this is our tool, so apply the appropriate skepticism. Here's what it actually does: it runs 15 real buyer-style queries across ChatGPT, Perplexity, Google AI Overviews, and Gemini — the four engines that drive nearly all AI search traffic — and checks whether your business name appears, where it ranks, which competitors are being recommended instead, and which third-party sources AI engines trust most for your category. You get a 0-100 AI Visibility Score, the exact prompts and responses, a breakdown by engine, and a list of cited sources you can act on. No signup required. One free scan per email every 7 days. Most scans complete in under a minute.
What it does better than most: shows you the actual cited sources, which is what we call "source intelligence" — the directories, review platforms, and content sources AI engines pulled from to build their answer. This matters because it tells you where to invest your AEO effort, not just whether you have a problem. What it doesn't do (yet): continuous monitoring, historical trend data, or hallucination accuracy detection. If you need those, look at LLMClicks or one of the paid platforms below.
LLMClicks.ai — 50 free credits with no credit card required. The differentiator is hallucination detection — it specifically flags when AI is describing your brand incorrectly (wrong pricing, fabricated features, inaccurate comparisons). This is genuinely valuable for SaaS brands where ChatGPT confidently inventing your pricing can poison demo calls. The founder built it specifically because his own product was being misquoted by ChatGPT. After the free credits, paid plans range from $49 to $399/month.
Visiblie — Tracks brand mentions across up to 8 AI models (ChatGPT, Gemini, Perplexity, Claude, DeepSeek, Grok, Meta AI, Mistral) on the Enterprise plan. The Starter plan covers ChatGPT only. Free trial available but the meaningful tier requires payment. Visiblie's accuracy tracking feature is similar to LLMClicks — it detects when AI hallucinates incorrect information about your brand. Worth a free trial if you specifically need broad multi-model coverage including the less common engines.
Part 4 · Paid Tools With Free Tiers or Trials Subscription Products With Try-Before-You-Buy
| # | Tool | Free option | Paid pricing | Coverage |
|---|---|---|---|---|
| 11 | Otterly.AI | Free trial | Subscription tiers | ChatGPT, Google AI Overviews, AI Mode, Gemini, Perplexity, Copilot |
| 12 | Peec AI | Free trial | Subscription tiers | ChatGPT, Perplexity, Deepseek, others |
| 13 | LLMrefs | Free trial | Most affordable AEO tool per their claim | ChatGPT GPT-5, AI Overviews, AI Mode, Gemini, Perplexity, Claude, Grok, Copilot, Meta, DeepSeek |
What You Actually Need to Know
Otterly.AI — One of the more established players, used by 20,000+ marketing professionals and recognized by G2 and Gartner. Tracks brand mentions and website citations across six AI platforms simultaneously. The dashboard surfaces both linked and unlinked mentions, which matters because most AI engines mention brands without linking out. Strong for marketing teams that need a polished dashboard rather than a one-time check. Free trial gives you a real sense of the product before you commit.
Peec AI — Designed for marketing teams that want daily monitoring with a 24-hour refresh cadence. Tracks both "used" sources (where your content informed an AI answer) and "cited" sources (where your URL is explicitly mentioned). Has a Google Looker Studio connector for piping data into custom dashboards. Best fit for content marketing teams already running structured reporting workflows.
LLMrefs — Trusted by 10,000+ marketers. Their pitch is keyword tracking instead of prompt tracking — you bring your existing SEO keyword list and they automatically generate fan-out prompts based on real conversations. Covers more AI models than almost anyone (10+ including ChatGPT GPT-5, Claude, Grok, Meta, DeepSeek). Claims to be the most affordable serious AEO tool on the market, though specific pricing requires a quote.
