HIG Doctor

HIG Doctor provides AI-driven guidance and auditing based on Apple's Human Interface Guidelines (HIG), offering platform-specific advice for iOS, iPadOS, macOS, watchOS, and visionOS. The tool is designed to help developers, design teams, agencies, and those building AI features ensure their user interfaces align with Apple's standards, reducing the need to manually consult extensive documentation. It structures the full Apple HIG into 14 distinct skills and 156 reference topics, enabling precise, context-aware answers to design questions and supporting accurate, platform-tailored UI decisions.

The platform includes several delivery methods: a browser-based audit tool that allows users to paste UI components or select samples for local analysis, a command-line interface (CLI), and an MCP server. All three use the same detection engine and a set of 348 rules to evaluate components for HIG compliance. No code leaves the user's browser during audits, maintaining privacy and security. js, and HTML, identifying common mistakes and highlighting HIG-aligned implementations.

HIG Doctor is structured to work with AI agents, providing them with the necessary context and references to answer specific design questions. Its progressive disclosure approach loads only the relevant portions of the HIG for each query, optimizing token usage and ensuring up-to-date, grounded responses. This enables AI agents to deliver accurate, platform-aware advice without overwhelming their context window, making it practical for both solo developers and larger teams.

The service is available for free, and users can install it via npx or try the audit feature directly in their browser. HIG Doctor is suitable for anyone seeking to automate or streamline the process of adhering to Apple's design language, from indie developers to consultancies delivering client projects. The tool aims to eliminate guesswork and ensure that UI designs meet Apple's requirements, supporting a range of platforms and technologies.
