Making Apple docs AI-readable.

sosumi.ai provides Apple Developer documentation in an AI-readable format by converting JavaScript-rendered pages into Markdown.

Replace developer.apple.com with sosumi.ai in any Apple Developer documentation URL:

Original:

https://developer.apple.com/documentation/swift/array

AI-readable:

https://sosumi.ai/documentation/swift/array

This works for all API reference docs, as well as Apple's Human Interface Guidelines (HIG).

Sosumi's MCP server supports Streamable HTTP and Server-Sent Events (SSE) transport. If your client supports either of these, configure it to connect directly to https://sosumi.ai/mcp.

Otherwise, you can run this command to proxy over stdio:

{
  "mcpServers": {
    "sosumi": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://sosumi.ai/mcp"]
    }
  }
}

See the website for client-specific instructions.

This service is an accessibility-first, on‑demand renderer. It converts a single Apple Developer page to Markdown only when requested by a user. It does not crawl, spider, or bulk download; it does not attempt to bypass authentication or security; and it implements rate limiting to avoid imposing unreasonable load.

Content is fetched transiently and may be cached briefly to improve performance. No permanent archives are maintained. All copyrights and other rights in the underlying content remain with Apple Inc. Each page links back to the original source.
