Amzn-User
Amazon's user-triggered fetcher - retrieves a page live when a user's question to Alexa or another Amazon AI needs it.

| Respects robots.txt | Yes |
Amzn-User fires when a user action requires fetching live information from the web - for example, an Alexa question whose answer needs a current page. It is Amazon's equivalent of ChatGPT-User or Claude-User: on-demand, human-initiated fetches rather than bulk crawling.
Amazon documents that Amzn-User traffic supports user actions and is not used for generative AI model training, and it carries its own robots.txt token so it can be controlled independently of Amazonbot and Amzn-SearchBot.
