Buy for Me is Amazon's AI shopping agent. When a requested item is unavailable on Amazon, it visits another brand's website, selects the product, and fills in the customer's name, address, and payment information to complete checkout. It is presented as part of the shift toward AI-assisted product discovery and purchasing outside Amazon's own marketplace.

Alexa+ Shopping is Amazon's AI shopping assistant for answering shopper questions in the Amazon app. The service incorporates promotional content and advertising into AI-generated shopping interactions.

Commerce Agents is Anthropic's reference implementation for building shopping agents for customers and merchant agents for back-office staff with Claude. It defines each agent through prompts, skills, tool contracts, grounding, memory, approval gates, and backend interfaces, and provides runnable examples for retail, travel, telecom, and entertainment. The shopping agent searches and compares products, plans purchases, fills carts, answers order and policy questions, and maintains customer memory. The merchant agent analyzes performance, manages listings and inventory alerts, handles pricing and promotions, and drafts campaigns; its writes are staged until a host approves them. The agents can run through the Anthropic Messages API, Claude Agent SDK, or Managed Agents, and the repository provides a Claude Code plugin for scaffolding or reviewing commerce agents.

Basement is an AI shopping assistant available as an iPhone app and Chrome extension. It reads product pages, searches for better prices, and aggregates user feedback from Reddit, Trustpilot, and X to help assess a product’s legitimacy, reviews, and value.

NorthCinder is an open-source, local-first MCP server for AI shopping agents. It compares products from user-selected sources against a buyer's criteria, explains rankings and exclusions, shows source facts and unverified details, and normally returns up to three useful options rather than claiming one universal best product. Its research workflow provides separate product and seller guides, creates a research plan, and uses controlled research tools; results remain provisional when sources conflict or do not identify the exact item or seller. Purchasing is a separate human-in-the-loop decision: each checkout requires fresh approval for one exact offer and unit, with the merchant, variant, price, known total, and spending cap signed into a single-use approval. It rejects raw card details, using an opaque payment token for supported automated checkout or handing the buyer a cart link. NorthCinder runs alongside an MCP-capable AI application. Its local setup requires Node.js 20 or later; the init command stores configuration locally and starts the MCP server and search engine in one process. The repository states that there is no hosted NorthCinder account or cloud service, and that order outcomes remain local.
