# KI-Sichtbarkeit-Check by nextlevels Review Free, no-login GEO checker that scores whether GPTBot, ClaudeBot, and PerplexityBot can crawl and cite your homepage in 30 seconds. ## Editor's Score: 61/100 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 - 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. ## Cons - 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. ## Pricing Free. - Free: Free Pricing reflects what we saw at the time of review (2026-11).

Directory: https://aitoolseekers.com This review: https://aitoolseekers.com/tools/ki-sichtbarkeit-check-by-nextlevels Methodology: https://aitoolseekers.com/how-verification-works ## Verdict 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. Best for: Solo site owners and German-speaking SEOs who want a quick technical AI-crawlability baseline. Not for: Anyone needing citation tracking, multi-page audits, or an English-language interface. ## Overview KI-Sichtbarkeit-Check is a single-purpose, browser-based tool from nextlevels GmbH, a German digital agency, that answers one question: can the major AI systems actually read your website? Enter a URL and within 30 seconds you get a 0-100 score built from checks against robots.txt rules for 16 AI crawlers, the presence and content of llms.txt, sitemap accessibility, and whether the homepage text is readable and attributable by AI systems. The tool simulates three specific crawlers: GPTBot (OpenAI training), ClaudeBot (Anthropic), and PerplexityBot, and it separately evaluates OAI-SearchBot, which is the bot that matters for actual ChatGPT search citations rather than training. That distinction between training crawlers and search-citation crawlers is a genuinely useful detail that many competing free tools blur. The check fetches only publicly reachable files, so it does not touch anything behind authentication. The interface is in German, which is both its natural home market and its clearest limitation for international users. There are no paid tiers, no account creation, and no email gate. The tool is narrow by design: it measures technical crawlability of the homepage only, and it explicitly does not measure whether any AI engine actually cites or recommends the site. ## Who should use it 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. ## FAQ Q: Does this tool cost anything? A: No. The tool is fully free with no sign-up, no email required, and no disclosed usage limits. Results appear in the browser within about 30 seconds. Q: Which AI crawlers does it check? A: 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. Q: Does it check my whole website or just the homepage? A: 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. Q: Will a high score mean AI tools will actually cite my site? A: 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. Q: Is the interface available in English? A: No. The interface is in German only. Users who do not read German will need a browser translation tool to interpret the results. Q: Does the tool store or process my site's content? A: It fetches only publicly reachable files: robots.txt, llms.txt, sitemap.xml, and the homepage. No authentication-protected content is accessed.
