Custom Hacker News summaries in your inbox—build an AI Agent with Inngest and Render

The tutorial provides a comprehensive guide for developers to build an AI agent application that automates the process of searching Hacker News for specific topics and sending email summaries. The app's architecture consists of a PostgreSQL database with the pgvector extension, a full-stack Next.js application, and a cron job, all hosted on Render, which ensures secure communication across components. The AI workflow is orchestrated by Inngest using its AgentKit framework to define and manage AI agents, specifically a Search Agent and a Summarizer Agent, which dynamically handle queries and summarize results. The process includes creating vector embeddings of the news stories, indexing them, and utilizing a network of agents to achieve the desired outputs, culminating in sending summary emails to users. The guide encourages users to extend the app's capabilities and provides insights into deploying and managing the app on Render, highlighting the ease of use and integration offered by Render and Inngest in building scalable AI applications.
