architecturaldigest.in: AI crawler policy in robots.txt
robots.txt as fetched on 2026-10-10: architecturaldigest.in disallows 16 of 22 AI and search crawlers from the site root: ClaudeBot, Google-Extended, CCBot, meta-externalagent, Bytespider, Applebot-Extended, Amazonbot, cohere-ai, Diffbot, Timpibot, PerplexityBot, Claude-SearchBot, DuckAssistBot, Perplexity-User, Claude-User, meta-externalfetcher. That includes crawlers behind AI answers (PerplexityBot, Claude-SearchBot, DuckAssistBot, Perplexity-User, Claude-User, meta-externalfetcher).
The file refuses training crawlers and also some crawlers that power AI answers, so the site is likely to be missing from AI citations and the referral traffic that follows.
This reports what the file asks. It does not show whether a crawler can actually reach the site: many sites also block crawlers at their CDN or firewall, and some crawlers ignore robots.txt.
Training crawlers
Disallowing these keeps a site's content out of future model training. It does not remove what was already collected.
| Crawler | Operator | Status | How the file treats it |
|---|---|---|---|
| GPTBot | OpenAI | not disallowed | covered by the default rule |
| ClaudeBot | Anthropic | disallowed | named in the file |
| Google-Extended | disallowed | named in the file | |
| CCBot | Common Crawl | disallowed | named in the file |

| Applebot-Extended | Apple | disallowed | named in the file |
| Amazonbot | Amazon | disallowed | named in the file |
| cohere-ai | Cohere | disallowed | named in the file |
| Diffbot | Diffbot | disallowed | named in the file |
| omgili | Webz.io | not disallowed | covered by the default rule |
| Timpibot | Timpi | disallowed | named in the file |
Search and citation crawlers
These feed AI answer engines that cite and link their sources. Disallowing them can take a site out of AI answers and out of the referral traffic that comes with them.
| Crawler | Operator | Status | How the file treats it |
|---|---|---|---|
| OAI-SearchBot | OpenAI | not disallowed | covered by the default rule |
| PerplexityBot | Perplexity | disallowed | named in the file |
| Claude-SearchBot | Anthropic | disallowed | named in the file |
| DuckAssistBot | DuckDuckGo | disallowed | named in the file |
User-action fetchers
These fetch a page live when a person asks an assistant about it. Disallowing them stops the assistant reading the page for that person.
| Crawler | Operator | Status | How the file treats it |
|---|---|---|---|
| ChatGPT-User | OpenAI | not disallowed | covered by the default rule |
| Perplexity-User | Perplexity | disallowed | named in the file |
| Claude-User | Anthropic | disallowed | named in the file |
| meta-externalfetcher | Meta | disallowed | named in the file |
Classic search crawlers
