Applebot-Extended for Apple Intelligence (Complete 2026 Guide)

Applebot-Extended is a separate user-agent string Apple introduced for content used in Apple Intelligence training. The original Applebot crawls for Siri and Spotlight indexing. Applebot-Extended crawls specifically for Apple Intelligence model training purposes.

Per Apple's official documentation, Applebot-Extended operates as a distinct crawler with its own crawl patterns and robots.txt controls (https://support.apple.com/en-us/119829). Sites can block Applebot-Extended without blocking Applebot, or vice versa.

Per Apple's Apple Intelligence documentation, Applebot-Extended crawls content that may be used to train Apple Intelligence foundation models (https://support.apple.com/en-us/120320). The crawler respects robots.txt directives but operates independently of Apple's general search infrastructure.

The original Applebot serves Apple's search products including Siri suggestions and Spotlight results. Applebot-Extended serves Apple's AI training pipelines specifically. The crawl patterns overlap but the downstream use cases differ.

Applebot-Extended consumes more crawl budget than Applebot since Apple Intelligence training requires broader content coverage than search indexing. Sites that allow both crawlers may see higher request volume from Apple infrastructure than expected.

Per Six Colors' coverage of Applebot-Extended controls, the separate user-agent string gives site owners granular control over which Apple products can access their content (https://sixcolors.com/post/excluding-your-website-from-apples-ai-crawler/). Blocking Applebot-Extended prevents Apple Intelligence training use without blocking Siri or Spotlight indexing.

Robots.txt configuration for Apple infrastructure requires explicit directives. Applebot and Applebot-Extended are separate user agents with separate controls. The directives look like:

User-agent: Applebot
Disallow: /private/

User-agent: Applebot-Extended
Disallow: /ai-block/

Per Apple's documentation, Applebot-Extended respects all standard robots.txt directives including Allow, Disallow, and Crawl-delay. Applebot supports the same directive set.

The configuration flexibility allows sites to allow Applebot for Siri while blocking Applebot-Extended for Apple Intelligence training. The choice depends on the site's content licensing strategy and AI visibility goals.

Per Six Colors' analysis, blocking Applebot-Extended removes content from Apple Intelligence training data but preserves server resources for other crawlers. Allowing Applebot-Extended preserves AI visibility in Apple products but adds to total crawl load.

The strategic choice depends on the site's audience composition. iOS-heavy audiences benefit from Apple Intelligence visibility. Android-heavy audiences benefit less from Apple Intelligence visibility and may prioritize Google or Bing AI visibility.

Sites serving mixed audiences typically allow all major AI crawlers including Applebot-Extended, GPTBot, ClaudeBot, and Google-Extended. The trade-off favors visibility over resource conservation for sites with content-dependent business models.

You open your robots.txt file and review the Apple-specific user-agent directives. You check whether Applebot and Applebot-Extended are explicitly listed, allowed, or blocked.

You pull server logs and filter for Applebot and Applebot-Extended user-agent strings. You count request volume by week for each crawler separately. You compare against Googlebot volume.

You document the configuration decision. Block both for server cost reasons, allow both for visibility reasons, or differentiate based on content licensing strategy. You update robots.txt based on the documented criteria.

Note the gap. This post synthesizes 2025 and 2026 data from three sources: Apple's official documentation, Apple's Apple Intelligence training documentation, and Six Colors' analysis. Two non-public Apple crawler rate-limiting details remain unpublished. Replication required.
