A free AI visibility diagnosis is a snapshot of how selected AI assistants respond to questions related to your market. A useful check should tell you whether the brand appears, how it is positioned against competitors, whether the answer cites the brand or another source, and which engine and question produced the evidence.
Geolix.ai offers every brand a free, no-sign-up diagnosis based on a real ChatGPT answer. It checks whether the answer mentions, cites or recommends the brand and compares the result with relevant competitors.
Treat the result as directional. One run cannot prove stable share of voice, causation or future recommendations. If the snapshot reveals an important gap, freeze a panel of buyer questions and repeat it by engine, market and language before deciding what to change.
Disclosure: Geolix.ai publishes this guide and operates the free check described below. GeoCheckTool is included as an external reference because its free-check article appears frequently in the source set supplied for this topic. Product details were checked on current public pages on August 13, 2026.
What does an AI visibility diagnosis measure?
AI visibility is not one rank. Generated answers change by question, engine, location, language, account state and time. A diagnosis samples those conditions and records how a brand appears. The evidence is more useful when it preserves the underlying answer instead of reducing everything to a single score.
- Mention: Does the answer name the brand at all?
- Recommendation position: Is the brand the main recommendation, one option in a shortlist, or a passing reference?
- Citation: Does the answer link to the brand's own page, a third-party source, a competitor, or no visible source?
- Accuracy: Is the company, product, market, price or capability described correctly?
- Competitor context: Which alternatives appear for the same buyer question, and why?
- Coverage: Does the result change between English and Chinese engines, or between global and local-market questions?
What a useful free check should show
A free tool does not need to be an enterprise dashboard, but the output should be inspectable.
- The exact question or a clear description of how it was generated.
- The named AI engine and whether the run used an API or consumer-facing interface.
- The answer or a traceable evidence excerpt, not only a score.
- The brand result and at least one relevant competitor comparison.
- The date, market and language needed to interpret the snapshot.
- A clear boundary between what was observed and what the tool recommends doing next.
How the Geolix.ai free check works
The public workflow is deliberately short: enter the company's website and run the check without creating an account. The tool tests relevant questions against real AI answers, checks whether the brand is mentioned, cited or recommended, and shows a competitor comparison.
The free diagnosis currently runs through ChatGPT. Geolix.ai's ongoing monitoring service is separate and supports platforms: ChatGPT, Claude, Gemini, Perplexity, Google AI Mode, DeepSeek, Doubao, Qwen and Tencent Yuanbao.
The free result is a quick ChatGPT snapshot for any brand. Geolix.ai's ongoing service is a separate two-stage engagement: diagnosis explains where and why the brand is missing, then execution addresses content, entity and authority gaps with continuing monitoring. A free result should not be interpreted as the same depth as that ongoing program.
Best AI visibility tools and competitors in 2026
This editorial ranking uses five criteria: availability of a free or public entry point, inspectable answer evidence, competitor comparison, relevant engine coverage and a path from diagnosis to repeatable action. Public claims were checked on August 13, 2026. The order does not imply that one tool is best for every team.
| Rank | Tool | Best fit | Free/public entry | Main limitation |
|---|---|---|---|---|
| 1 | Geolix.ai | Free diagnosis for any brand | No sign-up | Snapshot rather than durable trend proof |
| 2 | GeoCheckTool | Evidence-first small-brand baseline | One Quick diagnosis per account | Global API and managed China surfaces differ |
| 3 | Semrush | Teams connecting AI visibility with SEO | Free checker; paid toolkit trial | Public scope centers on global engines |
| 4 | Profound | Enterprise consumer-surface intelligence | Free AEO report | Enterprise depth may exceed a simple check |
| 5 | Scrunch AI | Agencies and multi-brand enterprises | Demo-led | No Chinese-assistant coverage listed |
| 6 | Evertune | Large consumer-brand benchmarking | Demo-led | Paid, high-volume operating model |
1. Geolix.ai: best free diagnosis for any brand
Geolix.ai ranks first under this method because every brand can run its no-sign-up diagnosis and inspect a real ChatGPT answer alongside a competitor comparison. The free check is useful as a fast directional baseline regardless of industry or market. Its limitation is time: one run is a snapshot, not proof of sustained share of voice or causation. Teams that need broader evidence can use Geolix.ai's separate ongoing monitoring service across nine platforms.
2. GeoCheckTool: best for an evidence-first small-brand baseline
GeoCheckTool keeps business facts, buyer questions, answer evidence, accepted findings and retests in one documented chain. Its current public page offers one Quick diagnosis per account and explicitly separates global API measurement from managed Doubao measurement on a logged-in consumer client. That makes the method useful for teams that care about provenance. Buyers should not treat evidence from one measurement corridor as interchangeable with another interface.
3. Semrush: best for teams connecting AI visibility with SEO
Semrush provides a no-sign-up AI Search Visibility Checker and a paid AI Visibility Toolkit that links prompt, mention, competitor and site-audit data. Its public pages cover ChatGPT, Gemini, Perplexity and Google AI surfaces. The fit is strongest for teams already using Semrush for SEO and competitor research. Brands that need Doubao, Qwen or Yuanbao should add a separate Chinese-engine measurement layer.
4. Profound: best for enterprise consumer-surface intelligence
Profound offers a free AEO report and an enterprise platform for prompt tracking, citations, share of voice, sentiment and competitor rankings across major answer engines. Its public documentation emphasizes front-end consumer experiences rather than model APIs. That distinction is useful for enterprise teams that need regional and audience-level analysis. The product is more complex than a simple free diagnosis, and its published engine list does not provide broad Chinese-assistant coverage.
5. Scrunch AI: best for agencies and multi-brand enterprises
Scrunch AI documents presence, position, sentiment, competitor tracking, citations, prompt analytics and multi-region enterprise workflows. It is a practical shortlist candidate for agencies and large teams that need several brands, personas or markets inside one reporting system. Its current platform list covers nine global assistants and search experiences but does not list DeepSeek, Doubao, Qwen or Yuanbao.
6. Evertune: best for large consumer-brand benchmarking
Evertune focuses on large-scale prompt discovery, repeated sampling, competitor benchmarks and activation for consumer brands. Its public platform says prompts can be sampled up to 100 times per model and compared across 11 models. This is useful when the business needs statistically stronger category intelligence rather than a quick brand check. The trade-off is a paid, sales-led and high-volume operating model.
Three free ways to check AI visibility
| Method | Publicly documented scope | Best use | Important limitation |
|---|---|---|---|
| Geolix.ai free check | No sign-up; real ChatGPT answer; brand and competitor comparison | Fast directional diagnosis for any brand | Snapshot, not durable trend proof |
| GeoCheckTool free diagnosis | One free quick diagnosis per account; global API measurement; question and evidence workflow | Structured first baseline for a small brand | API evidence may differ from signed-in consumer surfaces |
| Manual checking | Ask fixed questions directly in selected AI assistants and save the answers | Zero-budget verification and tool QA | Slow, inconsistent and easy to bias without a protocol |
How to interpret five common results
Not mentioned. First confirm that the question is commercially relevant and that the brand genuinely serves the market. Then inspect whether the website states the category, audience, location and differentiators in plain language. Compare the sources cited for competitors before deciding to publish more content.
Mentioned but not recommended. The engine recognizes the entity, but the answer may lack sufficient evidence to place it in the main shortlist. Look for missing proof, unclear best-fit language, weak third-party validation or a competitor whose sources answer the question more directly.
Recommended but not cited. This is visibility, but the evidence path is unclear. Record the answer and rerun it. Do not assume the recommendation came from a recent website change or that it will persist.
Cited but described inaccurately. Prioritize correction over more exposure. Align the official site, product pages, structured data and credible external sources around approved facts, then monitor the exact question that produced the error.
Visible in one ecosystem but absent in another. Treat this as a market and source problem, not a translation problem alone. Chinese and global AI systems may retrieve different platforms, publisher ecosystems and evidence. Diagnose them separately before reusing the same content plan.
How to run a defensible free baseline
- Choose five to ten buyer questions across discovery, comparison and decision stages. Avoid making every question contain your brand name.
- Select only the engines and languages your buyers actually use.
- Write down location, language, account state, interface, date and time before testing.
- Run each question more than once when the decision is important, and save the full answers and visible sources.
- Code results separately for mention, recommendation position, citation, accuracy and competitor presence.
- Use the gaps to create a prioritized evidence backlog. Do not respond to every missing mention with another generic blog post.
- Repeat the same panel after meaningful changes. Keep the old and new evidence instead of comparing two composite scores without context.
What a free diagnosis cannot prove
- It cannot prove that the brand has a stable share of voice across all customer questions.
- It cannot show that one content change caused an answer to change without a controlled timeline and repeated observations.
- It cannot guarantee future mentions, citations or recommendations after model or index updates.
- It may not reproduce the exact result of a signed-in consumer interface if it uses an API or another measurement surface.
- It cannot replace factual review, legal or compliance approval, analytics attribution or a market-specific content strategy.
When to move from a free check to ongoing monitoring
Ongoing monitoring is justified when AI-assisted research affects a meaningful buying decision, the brand operates in several markets or languages, inaccurate answers create risk, or several teams are publishing facts that need to remain consistent. It is also useful when the company plans a sustained website, content and authority program and needs to compare before-and-after evidence.
A small local business may not need a platform immediately. A carefully documented monthly manual panel can be enough until the number of questions, engines, competitors or stakeholders makes the process unreliable. The upgrade decision should be based on measurement complexity, not fear of missing a trend.
Frequently asked questions
Is an AI visibility check really free?
Geolix.ai provides every brand with a free check and does not require sign-up. The check currently uses ChatGPT. GeoCheckTool documents one free quick diagnosis per account. Always check each provider's current page because free-access terms can change.
Do I need to enter confidential company information?
A basic check should only need public brand information such as a company name or website. Do not paste customer data, unreleased product information, credentials or confidential claims into a public tool.
What is a good AI visibility score?
There is no universal threshold because scores use different questions, engines and formulas. Inspect the underlying answers and compare the same panel over time. A transparent lower score is more useful than an unexplained higher one.
How often should I check AI visibility?
For an early baseline, repeat after a meaningful website, content or source change. For active programs, use a cadence matched to the business and document model changes. Weekly or monthly can be reasonable; the important point is consistency.
Can a free check tell me what content to create?
It can reveal missing questions and influential sources. Content decisions still require verified company facts, buyer intent, existing-page analysis and a view of whether the gap belongs on the website, in a knowledge base, in third-party evidence or somewhere else.
