Problem
People manage a large volume of email and chat messages across multiple channels, making it difficult to keep up with replies, recall past conversations, or send quick updates while working. This creates friction because users must constantly switch between different messaging apps and their other tools, slowing down everyday communication and response times.
Solution
SlyOS provides a unified inbox that aggregates email, iMessage, SMS, WhatsApp, and other channels into one place, with an AI assistant called "The Brain" that knows the user's contacts, drafts replies in their voice before being asked, tracks follow-ups, and finds past messages. Users can fix any message with one-tap rewriting tools—Shorter, Fix grammar, or More direct—that preserve their natural writing style. The system also works inside ChatGPT and Claude through a custom MCP endpoint, letting users ask questions like "what needs a reply" or "what someone said yesterday" and have the AI fetch context and send messages directly from the AI interface. SlyOS maintains privacy by never training models on user messages, reading iMessage, SMS, and WhatsApp on-device, and allowing full data export at any time.
Target Audience
Primary users are individual professionals and power users of AI assistants who want to consolidate their personal and work messaging and delegate email handling to AI. The product also serves small businesses that need AI-driven customer support tied to their e-commerce and database systems.
