Double Check
This is a specialized tool for flagging potential scams in messages and images, with a focus on common US fraud patterns. It analyzes text from emails, SMS messages, and screenshots to identify phishing attempts, impersonation scams, and other suspicious content. You'd reach for this when building customer support tools, email clients, or messaging apps where you want to warn users about potential fraud before they click links or share personal information. The server runs as a hosted service over streamable HTTP, so you don't need to manage any local detection models or maintain fraud pattern databases yourself.
