Eine quellgestützte Karte von KI-Fetchern, Agenten und Kontrollen.

User-triggered fetcher used for certain actions in ChatGPT and Custom GPTs; it is not an automatic web crawler.

Roboterverhalten

OpenAI says robots.txt rules may not apply because these requests are user-initiated.

Identitätsnachweis

OpenAI publishes IP ranges for ChatGPT-User requests; the user-agent string remains spoofable.

Retrieves web content in response to user-initiated Claude requests.

Roboterverhalten

Anthropic says its bots honor robots.txt directives, including Claude-User.

Identitätsnachweis

Anthropic's crawler guidance links a current source-IP list; do not trust the token alone.

User-triggered fetcher that may visit a page to help answer a Perplexity user's question; it is not used for web crawling or foundation-model training.

Roboterverhalten

Perplexity says this fetcher generally ignores robots.txt because the request was initiated by a user.

Identitätsnachweis

Perplexity publishes IP ranges for Perplexity-User; combine the token and source IP rather than trusting the token alone.

Used by agents hosted on Google infrastructure to navigate the web and perform actions upon user request.

Roboterverhalten

Google says user-triggered fetchers generally ignore robots.txt rules because the fetch was requested by a user.

Identitätsnachweis

Google publishes user-triggered-agent IP ranges and is experimenting with Web Bot Auth for the agent.bot.goog identity.

Supports user actions such as fetching current web information to answer Alexa queries on a user's behalf; Amazon says it is not used for generative-AI model training.

Roboterverhalten

Amazon says because Amzn-User actions can be user-initiated, it may not follow all robots.txt directives.

Identitätsnachweis

Amazon publishes IP addresses for Amzn-User; use source verification in addition to the token.

Automatic crawler used to surface websites in ChatGPT search results.

Roboterverhalten

Managed with the OAI-SearchBot token in robots.txt.

Identitätsnachweis

Match the token with OpenAI's published SearchBot IP ranges; a user-agent string alone is not proof.

Navigates the web to improve the relevance and accuracy of Claude search responses.

Roboterverhalten

Anthropic says its bots honor robots.txt directives.

Identitätsnachweis

Anthropic's crawler guidance links a current source-IP list; do not trust the token alone.

Automatic crawler designed to surface and link websites in Perplexity search results; Perplexity says it is not used to crawl content for foundation-model training.

Roboterverhalten

Perplexity recommends managing PerplexityBot through robots.txt.

Identitätsnachweis

Perplexity publishes IP ranges for PerplexityBot; combine the token and source IP rather than trusting the token alone.

Apple web crawler used for search experiences including Spotlight, Siri, and Safari; Apple says crawled data may also support foundation-model training and current-content context for AI outputs.

Roboterverhalten

Applebot respects standard robots.txt directives in general search crawls.

Identitätsnachweis

Apple documents reverse-DNS verification under *.applebot.apple.com and publishes Applebot IP CIDR ranges.

Amazon search crawler used to improve search experiences in Amazon products and services, including eligibility for experiences such as Alexa; Amazon says it is not used for generative-AI model training.

Roboterverhalten

Amazon documents robots.txt allow/disallow support for its crawlers.

Identitätsnachweis

Amazon publishes IP addresses for Amzn-SearchBot; use source verification in addition to the token.

Automatic crawler for content that may be used to train OpenAI generative AI foundation models.

Roboterverhalten

Managed separately with the GPTBot token in robots.txt.

Identitätsnachweis

Match the token with OpenAI's published GPTBot IP ranges; a user-agent string alone is not proof.

Collects public web content that could potentially contribute to Anthropic model training.

Roboterverhalten

Anthropic says its bots honor robots.txt directives.

Identitätsnachweis

Anthropic's crawler guidance links a current source-IP list; do not trust the token alone.

Amazon crawler used to improve products and services; Amazon says collected content may also be used to train Amazon AI models.

Roboterverhalten

Amazon documents robots.txt allow/disallow support for its crawlers.

Identitätsnachweis

Amazon publishes IP addresses for Amazonbot; use source verification in addition to the token.

Publisher control for whether Google-crawled content may be used for future Gemini model training and specified grounding uses.

Roboterverhalten

Google-Extended is a robots.txt product-control token and does not affect Google Search inclusion or ranking.

Identitätsnachweis

Not a request identity. Do not look for Google-Extended as a standalone HTTP user-agent in traffic logs.

Publisher control for whether Applebot-crawled content may be used to train Apple's general-purpose foundation models.

Roboterverhalten

Applebot-Extended is configured in robots.txt but does not itself crawl webpages.

Identitätsnachweis

Not a request identity. Traffic should be attributed to Applebot, not Applebot-Extended.

Automated crawler that collects public web data for Common Crawl's open web-crawl repository.

Roboterverhalten

Common Crawl documents robots.txt support for CCBot.

Identitätsnachweis

Common Crawl publishes dedicated IP ranges and reverse-DNS guidance; the project also warns that clients can falsely claim the CCBot user-agent.
