Inbox Zero is an AI-powered email assistant designed to help you reach inbox zero faster by automatically organizing your inbox, drafting replies in your tone, and tracking follow-ups. It explains how the AI should handle your inbox via Cursor Rules, and offers features such as Reply Zero to monitor messages requiring a response, Smart Categories to auto-classify senders, Bulk Unsubscriber to unsubscribe and archive unread messages, Cold Email Blocker to filter out unsolicited mail, and Email Analytics to reveal activity trends over time. The project emphasizes self-hosting with Docker or running a hosted version, uses Next.js, Tailwind, Prisma, and Redis for a performant stack, and supports custom LLM providers and external OAuth integrations (Google and Microsoft). It includes instructions for local development, Docker-based self-hosting, and production deployment, and provides guidelines for enabling Google Pub/Sub push notifications for real-time email updates. Overall, Inbox Zero aims to reduce manual inbox management and accelerate productive email workflows.
