Buy on Amazon inside my own logged-in account

The AI’s Comet browser shopped Amazon inside users' own signed-in Prime accounts — loading pages, comparing products, filling carts and completing purchases at the user's direction — until Amazon sued, arguing the access was the user's permission but not Amazon's authorization. A district court enjoined Comet in March 2026; on August 4, 2026 the Ninth Circuit vacated the injunction, holding the agent is a tool and the user is the one buying, while leaving terms-of-service claims live.

How it works

  1. User signs into their own Amazon account in Comet
  2. Asks the agent to buy a specific product
  3. Agent navigates Amazon, compares options and fills the cart
  4. Agent completes checkout with stored payment details
  5. Amazon sues and wins a March 2026 injunction
  6. Ninth Circuit vacates it on August 4, 2026 under federal hacking law

Why it’s worth knowing

A federal appeals court had to decide who is legally 'buying' when your agent checks out — and said it is you.
