Zero Overview
Zero is a revolutionary AI-powered email client built from the ground up to fundamentally change how professionals manage their communication. Frustrated with email clients that haven't evolved in decades, the creators of Zero designed an intelligent assistant that lives inside your inbox. Its core mission is to help you spend less time managing emails and more time on what truly matters. Backed by Y Combinator and built on a foundation of open-source principles, Zero offers a transparent, secure, and community-driven solution for inbox overload.
The platform is engineered for speed and efficiency, catering to power users who value their time. With a lightning-fast interface and comprehensive keyboard navigation, users can fly through hundreds of emails in minutes. The AI acts as a personal copilot, capable of understanding context, summarizing complex discussions, and generating appropriate responses, freeing you from the tedious task of manual email composition.
How to use Zero
Getting started with Zero is simple and intuitive. First, sign up on the website and connect your existing email account(s). Once connected, your inbox will be enhanced with AI capabilities. You can immediately start using keyboard shortcuts (like ⌘K for search or ⌘R for reply) to navigate your emails at the speed of thought. To handle long threads, simply use the AI Summary feature to get a concise overview. When you need to respond, let the AI draft a reply and then adjust the tone (e.g., neutral, professional) and length as needed before sending. The most powerful feature is 'Chat with Zero,' where you can use natural language commands like "Find the invoice from Stripe," "Summarize what Alex said about the new design," or "Schedule a meeting with Sarah" to manage your inbox without manual searching or clicking.
