# Sidekick

> Sidekick is an AI-powered SMS assistant for frontline and deskless workers in manufacturing, auto dealerships, and retail. Workers text questions in any language and get instant answers pulled from their company's own documents - no app, no login, works on any phone. They can send photos of equipment for identification or voice memos when their hands are dirty. When Sidekick cannot answer, it escalates to a manager over SMS and learns from the reply.
