What to know

  • Apple uses a multi-step AI system to generate App Store review summaries in iOS 18.4.
  • The summaries aim to be balanced, inclusive, and reflect real user sentiment.
  • Spam, profanity, and irrelevant reviews are filtered out before summarization.
  • Human raters reviewed thousands of summaries to ensure quality and safety.

Apple has introduced a new feature in iOS 18.4 that uses artificial intelligence to summarize user reviews on the App Store. This system is designed to help you quickly understand what people think about an app or game without reading through hundreds of individual reviews.

The process starts by filtering out reviews that contain spam, offensive language, or fraudulent content. Only relevant and appropriate reviews are considered for summarization. Apple uses a multi-step large language model (LLM) system to analyze the remaining reviews. The AI extracts key insights, groups similar themes, and balances both positive and negative feedback to create a short summary, usually between 100 and 300 characters long.

Apple has trained its AI models specifically for this task. Each step in the process uses a model fine-tuned to ensure the summaries are accurate and truly reflect what users are saying. The company also addresses challenges such as changing app features, bug fixes, and the dynamic nature of user feedback. This means the summaries adapt as new reviews come in and as apps are updated.

To maintain high standards, Apple had human raters review thousands of AI-generated summaries during development. These raters checked for safety, accuracy, helpfulness, and proper composition. Summaries had to be free from harmful content and faithfully represent the input reviews. Automated checks also help direct human attention to areas where it is most needed.

Apple says the goal is to provide you with a clear, concise overview of user sentiment, making it easier to decide whether to download or purchase an app. The company emphasizes that the summaries are designed to be helpful, safe, and up to date, reflecting the latest user experiences and feedback.
