Free, no-login GEO checker that scores whether GPTBot, ClaudeBot, and PerplexityBot can crawl and cite your homepage in 30 seconds.

The fastest zero-friction way to check whether your homepage is technically open to the three major AI crawlers, with a clear 0-100 score and per-crawler breakdown. It only checks the homepage and cannot tell you whether any AI actually cites you, which limits its usefulness compared to tools like VisRank that audit deeper. Teams needing ongoing citation monitoring or multi-page audits should look elsewhere.
What is KI-Sichtbarkeit-Check by nextlevels?
Free AI visibility checker by nextlevels GmbH, a German digital agency (founded 2026 as a tool). Enter a URL and get a 0-100 score in 30 seconds: it simulates GPTBot, ClaudeBot and PerplexityBot, checks robots.txt rules for 16 AI crawlers, llms.txt, sitemap and whether the homepage text is readable and attributable. No sign-up, no email, results instantly in the browser. Interface in German.
How we scored KI-Sichtbarkeit-Check by nextlevels
Ease of use scores near the top because the tool genuinely has zero friction: no account, no email, results in 30 seconds, and the crawler distinction between OAI-SearchBot and GPTBot shows real technical care. Value is high because it is free with no disclosed limits. Capability is limited to a single homepage snapshot across 16 crawlers with no citation tracking, multi-page auditing, or actionable fix guidance, putting it well below VisRank and Corank on depth. Delivery scores very low: the tool was founded in 2026 and social profiles could not be confirmed at all, meaning there is essentially no track record, no user sentiment to evaluate, and no independent verification that the tool performs as described beyond the vendor's own page.
Pros and cons
What we liked
- Genuinely free with no sign-up, no email gate, and no usage limits disclosed, making it the lowest-friction entry point in the category.
- Correctly distinguishes OAI-SearchBot (ChatGPT search citations) from GPTBot (training), a nuance that matters for anyone optimizing for AI answer visibility rather than just blocking training crawlers.
- Checks 16 AI crawlers against robots.txt rules in a single pass, covering a wider crawler list than many free alternatives.
Where it falls short
- Scope is hard-capped at the homepage: internal pages, blog posts, and product pages are never checked, so a site with a permissive homepage but blocked subfolders will get a misleadingly high score.
- The interface is German-only, which makes the tool effectively inaccessible to non-German-speaking users without translation assistance.
- The tool explicitly does not measure whether any AI engine actually cites or recommends the site, so a perfect score of 100 tells you nothing about real AI mention frequency or brand visibility in AI answers.

Who should use KI-Sichtbarkeit-Check by nextlevels?
A solo website owner or freelance SEO who suspects their robots.txt might be accidentally blocking AI crawlers will get real value here in under a minute, with zero setup cost. It is also a practical first-step diagnostic for German-language digital agencies onboarding new clients: paste the URL, screenshot the score, and you have an instant conversation starter about GEO readiness.
Anyone who needs more than a homepage snapshot should look elsewhere. VisRank, already in this directory, audits SEO, AEO, and AI search readiness across a broader scope and also runs in about 30 seconds. For teams that want ongoing monitoring of whether AI engines are actually citing their brand, Corank offers a managed service that goes well beyond a one-time technical check.
Skip it if: Anyone needing citation tracking, multi-page audits, or an English-language interface.

Which AI crawlers does it check?+
It simulates GPTBot, ClaudeBot, and PerplexityBot, and separately checks OAI-SearchBot for ChatGPT search citation eligibility. In total it evaluates robots.txt rules for 16 AI crawlers.
Does it check my whole website or just the homepage?+
Only the homepage of the entered domain is analyzed, along with the site-level files robots.txt, llms.txt, and sitemap.xml. Internal pages and subfolders are not audited.

No. The tool explicitly does not measure whether any AI engine cites or recommends the site. A high score means the technical access conditions are met, not that citations will follow.

No. The interface is in German only. Users who do not read German will need a browser translation tool to interpret the results.
Does the tool store or process my site's content?+
