Zethos company profile

Zethos is an AI-powered personal assistant for macOS that actually executes tasks—not just talks about them. While other AI tools draft suggestions and wait for approval, Zethos sends emails, creates calendar events, posts to Slack, files Linear tickets, and manages your workflows end-to-end. The platform integrates with Gmail, Slack, Google Calendar, Linear, GitHub, Notion, and more to take real action on your behalf. Say "email Sarah that I'll be 10 minutes late" and it's sent. Say "create a Linear ticket for the login bug and assign it to the team" and it's done. No copying, no pasting, no manual execution. Zethos features Deep Sweep technology that analyzes your communication history to learn your writing voice, relationships, and work context. It knows who your VIPs are, how you communicate with each person, and writes in your style—then executes without hand-holding. Key capabilities include natural language task execution, one-click AI email and slack replies, proactive activity monitoring, autonomous background agents, and sub-2-second response times. Built for professionals who are tired of AI that just answers questions. Zethos is the AI that works.
