The Best Free AI Visibility Checker in 2026 (No Credit Card)

Quick Answer You can check your brand's AI visibility for free, without a credit card. The manual method, asking ChatGPT, Gemini, Perplexity, and Claude category questions and recording whether your brand appears, costs nothing but takes 30-45 minutes. Tool-based free checkers are faster: SKYA offers a free scan across four AI platforms and a 7-day free trial (no card) on ChatGPT and Gemini; HubSpot's AEO Grader is free for basic benchmarking; Otterly.AI offers a 7-day free trial with no card. A good free check should show per-platform mentions, citations, competitor share of voice, and any factual errors, not just a single number. Free checks and trials are ideal for a baseline before you commit to paid monitoring.

Before you pay for any AI visibility tool, there's a sensible first question: what does my brand's AI visibility even look like right now? You shouldn't have to hand over a credit card to find out. And in 2026, you don't.

This guide covers the genuinely free ways to check your brand's visibility across AI assistants, what a good free check should actually show you, where free tiers hit their limits, and how to turn a baseline into a plan.

What "AI Visibility" Means Here

AI visibility is how often, how prominently, and how accurately your brand shows up when people ask AI assistants, ChatGPT, Gemini, Perplexity, Claude, and Google AI Overview, questions in your category. A free checker's job is to give you a snapshot of that: are you mentioned, are you cited, how do you compare to rivals, and is the AI getting your facts right?

For the full framework behind these metrics, see our pillar guide: AI Visibility Explained: How Brands Get Cited by ChatGPT, Gemini, Perplexity, and Claude.

The Two Ways to Check for Free

Option 1, The Manual Method (Free, ~30-45 minutes)

1. Write 10 category questions a potential customer would ask, "best [category] tool for [audience]", "top [category] companies", "alternatives to [competitor]".
2. Ask each in ChatGPT, Gemini, Perplexity, and Claude, in fresh sessions.
3. Record, per answer: brand mentioned (Y/N), your URL cited (Y/N), brand recommended (Y/N), and any factual errors.
4. Run the same questions with your top competitors' names in mind and count their mentions to estimate share of voice.
5. Keep the sheet and repeat monthly.

The manual method is completely free and genuinely informative. Its cost is your time, and its weakness is consistency, it's easy to phrase questions slightly differently each month and muddy your trend data. For the detailed walkthrough, see: How to Check If Your Brand Is Mentioned by ChatGPT (Free Methods + Tools).

Option 2, Free Tool-Based Checkers (Free, ~minutes)

Tool-based checkers automate the whole thing: enter your domain, and the tool queries the platforms and returns a scored report in minutes. Consistency is the advantage, the same queries, run the same way, every time.

The Best Free AI Visibility Checkers in 2026

SKYA, Free Scan and 7-Day Trial, No Credit Card

SKYA's free scan requires no credit card and reads your brand on ChatGPT, Gemini, Perplexity and Google AI Overview, with your top priority fixes. A 7-day free trial then tracks 10 prompts in one market on ChatGPT and Gemini, and the paid plans add a hallucination audit that flags where AI assistants are stating something factually wrong about your brand. It's designed as a real baseline, not a teaser: you see per-platform visibility, not just a single blended number. Best for: anyone wanting a complete, no-card baseline across every major platform with a hallucination check included.

HubSpot AEO Grader, Free Benchmarking

HubSpot's free AEO Grader benchmarks your site against competitors across ChatGPT, Perplexity, and Gemini. It's a solid, no-cost first diagnostic. Best for: a quick competitive benchmark. Limit: no ongoing tracking, no hallucination detection, fewer platforms.

Otterly.AI, 7-Day Free Trial, No Card

Otterly offers a 7-day free trial with no credit card, covering four AI search engines by default. It's a full-feature trial rather than a permanent free tier, so it's best used as a focused evaluation window. Best for: a time-boxed hands-on trial of a paid platform. Limit: reverts to paid after 7 days.

Semrush Free AI Visibility Checker

Semrush offers a free AI visibility checker that returns a quick score. Best for: existing Semrush users wanting a fast score. Limit: shallow depth outside the paid AI Toolkit.

A Note on "Free" Tiers vs "Free Trials"

There's a meaningful difference worth understanding:

• A free tier is permanently free within its limits, you can return to it indefinitely.
• A free trial (like Otterly's 7 days) is a temporary full-feature window that converts to paid.

For an ongoing zero-cost baseline you can re-run monthly, a free tier is what you want. For a deep hands-on evaluation before buying, a free trial is the better fit.

What a Good Free Check Should Show You

Not all "free checks" are equal. A single visibility score with no breakdown is nearly useless for deciding what to do next. A genuinely useful check shows:

1. Per-platform mentions, where you appear and where you're absent, engine by engine (you can be strong in ChatGPT and invisible in Perplexity).
2. Citations, whether your own URL is referenced as a source, not just your name in passing.
3. Competitor share of voice, how you stack up against named rivals across the same queries.
4. A hallucination check, whether the AI is stating anything factually wrong about you, since a confident error can cost you customers silently.
5. Prioritised fixes, the two or three highest-impact actions, so the baseline turns into a plan.

If a free checker gives you a number and nothing else, treat it as a smoke alarm, not a diagnosis.

Where Free Checks Hit Their Limits

Free is the right way to start. It's rarely enough to run a program. Free tiers typically cap:

• The number of queries tracked (often a handful vs the 30+ a real program needs)
• The number of competitors you can benchmark against
• Platform coverage on some tools
• Continuity, free checks are usually snapshots, not ongoing monitoring with trend history and alerts

The honest framing: use a free check to answer "do I have a problem?" When the answer is yes, and for most brands, it is, a paid tier answers "is the problem getting better or worse over time, and are my fixes working?" That second question needs continuity a one-time free check can't provide.

From Baseline to Plan

Once you have a free baseline, the next moves depend on what it shows:

• Broadly invisible across platforms → a content depth and topical authority problem. Start building comprehensive, well-structured content on your core topics.
• Mentioned but not cited → a content structure and schema problem. Restructure key pages so AI can cleanly lift and cite them.
• Hallucinations present → a source-data problem. Fix your site, directories, and Wikipedia/Wikidata. See: AI Hallucinations About Your Brand: How to Find and Fix Them.
• Losing share of voice to a rival → competitive intelligence. Study what that competitor publishes and earns in citations.

Frequently Asked Questions

Is there a free way to check my brand's AI visibility? Yes. You can check manually for free by asking ChatGPT, Gemini, Perplexity, and Claude category questions and noting whether your brand appears. Several tools also offer free checks: SKYA has a free scan with no credit card that scores your visibility across four AI platforms, HubSpot offers a free AEO Grader, and Semrush offers a free AI visibility checker. Free tiers are ideal for a baseline before committing to paid monitoring.

Which free AI visibility checker doesn't require a credit card? SKYA's free scan requires no credit card and scores your brand across ChatGPT, Gemini, Perplexity and Google AI Overview. HubSpot's AEO Grader is also free with no card for basic benchmarking. Otterly.AI offers a 7-day free trial with no credit card. Always confirm current terms on each vendor's site, as free-tier structures change.

What should a good AI visibility check show me? A useful AI visibility check should show, at minimum: whether your brand is mentioned across each major AI platform, whether your website is cited as a source, how you compare to competitors (share of voice), and whether the AI is stating anything factually wrong about you (a hallucination audit). A single visibility number without this breakdown is far less actionable than a per-platform, per-metric view with specific fixes.

Are free AI visibility checkers accurate? Free checkers are directionally accurate for a baseline, they'll reliably tell you whether you're broadly visible or invisible and flag obvious gaps. Their limits are depth and continuity: free tiers usually cap the number of queries, competitors, or platforms tracked, and rarely include ongoing monitoring or trend history. For a one-time baseline they're genuinely useful; for continuous tracking you'll eventually need a paid tier.

How long does a free AI visibility check take? A tool-based free check typically runs in a few minutes, you enter your domain and the tool queries the AI platforms and returns a scored report. The manual method takes longer, roughly 30-45 minutes to run a dozen queries across four platforms and record the results. Tool-based checks are faster and more consistent, which is why most people start there for a baseline.
