X-Ray Recaps generates spoiler-free text summaries of TV show episodes and seasons for Prime Video viewers, personalized to the exact point where they stopped watching. The feature launched in November 2024 on Fire TV and uses generative AI to analyze video content, dialogue, and subtitles.

The system is powered by Amazon Bedrock foundation models and custom models trained on Amazon SageMaker. It analyzes video segments together with subtitles and dialogue to produce descriptions of key events, characters, and plot developments. Amazon Bedrock Guardrails are applied to prevent spoilers from appearing in the output. In early 2025, the feature was briefly paused after errors surfaced, including an incorrect summary of the show Fallout.
