Apple Is Using Claude Inside the Company Workflow, Leaked Documents Show

A recent discovery hints that Apple may be using Anthropic’s Claude internally. The company’s latest Apple Support app update reportedly shipped with internal CLAUDE.md files.

Researcher and analyst Aaron Perris flagged the files on X (formerly Twitter).

Apple’s AI Workflow Leaked?

CLAUDE.md is a feature of Claude Code, Anthropic’s AI coding assistant. Developers drop these markdown files into their project directories, and Claude Code reads them at the start of every session. 

They’re used to set coding standards, define architecture decisions, specify preferred libraries, and define review checklists. 

They typically live in source repos and are not meant to ship inside production apps,” International Cyber Digest wrote. “Oh, and this also confirms Apple is using Claude internally.” 

In the shared screenshots, the first file describes a chat module that combines Juno AI with live human agents. It outlines three participant roles for message routing: client, agent, and assistant.

Notably, the architecture relies on conditional compilation flags such as JUNO_ENABLED and DEV_BUILD. The file also references an internal Apple bug-tracker entry, indicating it originates from a live codebase.

A second file documents SAComponents, a shared UI library that supports multiple Apple platforms, including visionOS. It separates UI from business logic and supports both SwiftUI and UIKit.

Claude files surfacing in a public build may signal a packaging error during release. It could also hint that Apple’s engineers may be incorporating Claude into how they build software internally.

Apple’s Public Ties to Anthropic Run Deep

Apple previously confirmed support for Claude Sonnet 4 in Xcode 26 in September 2025. Then, in February 2026, the company expanded this with Xcode 26.3. The update added native integration with the Claude Agent SDK.

The company is widely recognized for its tight control over hardware, software, and security. That self-contained approach has long shaped Apple’s reputation as one of the most security-focused product makers in the industry. 

The shipped CLAUDE.md files now indicate that Anthropic’s tools may be sitting alongside those resources, raising fresh questions about how Apple balances third-party AI use with its tightly controlled internal stack.
