AI bots · Apple Applebot-Extended: Apple’s AI training control
Applebot-Extended does not crawl. It tells Apple whether pages Applebot already fetches may train Apple’s foundation models. Here is what Apple publishes, linked to the source.
- Model training
- Follows robots.txt
- No verification published
Applebot-Extended at a glance
What Apple publishes about Applebot-Extended, with a link to the page each fact comes from. Copy the robots.txt rule you need, or check whether an IP really belongs to it.
What the operator says about Applebot-Extended
Each row links to the page it comes from. “Not published” means we could not find it in the operator’s own documentation.

Sample user agent
Only a robots.txt token is published — no full user-agent string. Apple says Applebot-Extended does not crawl webpages, so it has no user agent of its own.
robots.txt rules
Add one of these groups to the end of your robots.txt. The token is matched case-insensitively.
User-agent: Applebot-Extended
Disallow: /User-agent: Applebot-Extended
Allow: /A group named for Applebot-Extended replaces your User-agent: * rules for it. To keep it out of one folder only, change / to that folder, e.g. Disallow: /private/.
Check a request really came from Applebot-Extended
It sends no requests itself; the pages are fetched by Applebot. Verify those requests with the operator’s method: Source
# Step 1 — reverse lookup: the name must end in .applebot.apple.com
host 203.0.113.7
# Step 2 — forward lookup: the name must resolve back to the same IP
host <hostname-from-step-1>Check an IP against the official list
Open search.developer.apple.com/applebot.json, copy everything and paste it below with the IP from your log. The check runs in your browser.
JSON or one range per line. IPv4 and IPv6 ranges are both read.
Paste an IP address to check it.

Four facts that decide what to do
Every crawler page has the same table. These four rows answer most questions about a crawler.
What it is used for
Training, search or a user’s request. Blocking a training crawler keeps your pages out of future models; blocking a search crawler also removes you from answers that would have linked back.
Follows robots.txt
“Yes” is the operator’s own statement. “Partly” usually means fetches a person starts may skip robots.txt — ChatGPT-User, Perplexity-User and meta-externalfetcher say so.
Official IP list / reverse DNS
The only way to tell a real crawler from one that copies its user agent. If neither is published, the user agent is just a claim.
Not published
We could not find it in the operator’s own documentation. We do not fill gaps from third-party lists — those disagree with each other and go stale.
Facts were checked against the operators’ pages on the date shown on each crawler page. Operators change their docs; the source link is the place to confirm.
From a name in your logs to a rule
Four steps, all in the browser.
-
1
Find the crawler
Type the name from your logs or the company you are thinking of. Filter by purpose to see, say, every AI training crawler.
-
2
Open its page
Read what the operator says it is for and whether it follows robots.txt. Copy its official user agent to compare with your logs.
-
3
Build the rules
Tick crawlers in the table, choose Block or Allow, then copy or download the robots.txt groups.
-
4
Check the effect
Test the file with the robots.txt tester, and use the IP check on a crawler page to confirm a request is genuine.
How crawlers are grouped and how robots.txt applies
The directory groups crawlers the way TapCub’s bot rules do. robots.txt matching follows RFC 9309: a crawler obeys the one group whose User-agent matches its token, and only falls back to * when no group names it.
- A crawler with its own group ignores every
User-agent: *rule - Tokens are matched without regard to case; a typo matches nothing
- Some names are tokens only — Google-Extended and Applebot-Extended never visit
- Agents without a published token cannot be addressed in robots.txt at all
| Group | What it does | Effect of blocking |
|---|---|---|
| AI training | Collects pages for model training or datasets | Your future pages stay out of that operator’s training, if it follows robots.txt |
| AI search | Indexes pages for AI answers with links | You stop appearing as a cited source |
| AI agent | Opens a page for a person’s request | Assistants cannot open your page — when the agent honours robots.txt at all |
| Search engine | Classic search index | You leave that search engine; some, like Bing, also feed AI answers |
How four robots.txt files treat Applebot-Extended
Applebot-Extended reads the group whose User-agent line matches Applebot-Extended (case does not matter). If there is none it falls back to User-agent: *.
| robots.txt | Result for Applebot-Extended | Why |
|---|---|---|
User-agent: Applebot-Extended Disallow: / | Blocked | Its own group disallows the whole site. |
User-agent: * Disallow: / | Blocked | No group of its own, so it inherits the wildcard. |
User-agent: * Disallow: / User-agent: Applebot-Extended Allow: / | Allowed | A named group replaces the wildcard completely; the * rules no longer apply to it. |
User-agent: Applebot-Extended Disallow: /private/ | Allowed except /private/ | Only paths that start with /private/ are off limits. |
This is how the rules read under RFC 9309. Whether Applebot-Extended follows them is Apple’s statement in the facts table above.
Where AI crawler policies go wrong
Most problems come from the token or from what the crawler actually is.
Using a company name as the token
“OpenAI”, “Anthropic” or “ChatGPT” are not tokens. Use the exact token from the directory — GPTBot, ClaudeBot, OAI-SearchBot.
Blocking search with training
Blocking OAI-SearchBot or PerplexityBot removes you from AI answers that would link back. Decide per crawler, not per company.
Trusting the user agent
Anyone can send “GPTBot” in a header. Without an IP or reverse-DNS check the request is unverified.
Blocking by IP and losing the opt-out
Anthropic and Cohere warn that blocking their IPs stops them reading robots.txt, so the opt-out may not stick.
See which crawlers actually came
The directory tells you what crawlers say they do. TapCub separates humans from bots with five detection layers and 197+ rules, and reports AI crawlers on their own.

What is Applebot-Extended?
Applebot-Extended is a robots.txt token, not a crawler. Apple says it does not crawl webpages; it only determines how data crawled by Applebot may be used.
Does Applebot-Extended respect robots.txt?
Disallowing Applebot-Extended in robots.txt opts content out of that training. Apple says pages that disallow it can still appear in search results.
How do I block Applebot-Extended?
Add a group for its token: User-agent: Applebot-Extended then Disallow: /. Applebot-Extended sends no requests of its own — the rule tells Apple how it may use what Applebot crawls, and Applebot itself keeps crawling.
How can I tell a request really came from Applebot-Extended?
Applebot-Extended is only a robots.txt token, so there is no traffic of its own to verify. Requests come from Applebot; verify those with Apple’s method.
Will blocking Applebot-Extended remove me from Siri or Spotlight results?
Apple says pages that disallow Applebot-Extended can still be included in search results, and those rules are not used in ranking. Applebot keeps crawling.
How do I stop Apple using my pages in AI answers in Siri?
Apple says that use is controlled with the nosnippet meta tag. Applebot-Extended covers model training.
