Basement

About Basement

Basement is a shopping browser with agentic checkout. It learns your taste from the way you browse, keeps a Closet of everything you've ever bought, and finds the best price across the web. When you're ready to buy, it uses a single-use card scoped to that order, so your real card stays private and the purchase stays within a budget you set.

Review

Basement takes a focused approach: it's a browser built for shopping, not for general web use. It compiles your purchase history into a Closet, watches your browsing to understand preferences, and handles checkout through disposable cards powered by Crossmint. The tool is live on iOS and Chrome, and it's free.

Key Features

• Agentic checkout with single-use cards. Each purchase uses a card generated for that one order, capped by a budget you approve with your passkey. Your real payment method never reaches Basement or the merchant.
• Closet. A running record of everything you've bought, which the tool references to learn your taste and surface relevant items.
• Cross-web price hunting. The tool searches multiple stores to find the lowest price on a product you're viewing.
• Live chat on any page. You can talk to other shoppers browsing the same webpage directly inside the browser.
• Taste learning. The browser adapts to your preferences based on how you navigate and what you engage with, rather than relying on manual input.

Pricing and Value

Basement is free. The reference content does not describe any paid tiers, subscriptions, or in-app purchases. The value lies in consolidating scattered purchase records, automating price comparisons, and reducing card exposure during checkout.

Pros

• Single-use cards keep your actual payment details off merchant sites and enforce a hard spending cap.
• The Closet centralizes purchase history, removing the need to log into multiple store accounts to track past orders.
• Price scanning across the web can surface lower-cost options you might otherwise miss.
• Works on both mobile (iOS) and desktop (Chrome), covering the two most common shopping environments.
• Free to use, with no upfront cost or subscription commitment.

Cons

• Checkout still requires manual confirmation before the purchase completes; it does not yet operate fully autonomously.
• Only available on iOS and Chrome, so Android users and those on other browsers can't use it.
• Not well suited for people who shop infrequently or prefer to manage every step of a purchase themselves, since the Closet and taste learning gain relevance with regular use.

Basement fits most naturally for frequent online shoppers who want a single place to track purchases and hunt for better prices. The single-use card model addresses a real concern around handing over payment details to an agent, though the confirmation step means it's still a semi-automated process. Users who want a hands-off, fully autonomous shopping assistant will need to wait for the roadmap features the team has mentioned.
