### 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.
