# Deck

> Deck gives AI agents authenticated access to any website without an API. Deck's browser agents sign in as your users, fetch data, fill out forms, and make payments, then return structured JSON to your product — at any scale.

Teams use Deck to pull bills and statements from utility and vendor portals, file claims and applications on government and payer sites, pay invoices on supplier and utility payment pages, and update the card on file at merchants. Deck stores your users' credentials in an encrypted vault, handles sign-in, MFA, and captchas, runs tasks on demand, on a schedule, or chained into workflows, and records every run with screenshots and agent reasoning. If a person can do it in a browser, a Deck agent can do it too.

Every agent session runs in a fully isolated virtual machine with credential vaulting, full audit trails, human-in-the-loop approvals, a kill switch, and session replay. Deck is SOC 2 Type II and PCI DSS Level 1, and used by teams at companies including Sunrun, BILT, Entrata, Wander, and EY.
