I built this because I wanted a daily briefing on my sports teams and stocks without checking five different apps. You pick your topics, set a schedule, and an agent researches and writes the email for you.
Stack: Convex for backend/scheduling, Resend for email delivery, Claude for agent logic.
Setup takes ~30 seconds through the UI, or describe what you want to the chat agent and it configures itself. Self-hostable, but bring your own API keys (live is completely free).
