🚀 I Built an AI Tool That Automatically Replies to Emails & Handles Follow-ups

Replyzen AI is a micro-SaaS platform that automates email conversations by connecting user inboxes (Gmail/Outlook/IMAP), analyzing messages with LLM-based AI, and generating context-aware replies with automatic follow-ups. The system is built with Next.js and Tailwind CSS on the frontend, FastAPI with async processing on the backend, and PostgreSQL via Supabase, with background workers handling email sync, AI processing, and scheduled tasks.
