Hey HN! I'm excited to show off this really fun project I put together. I originally built this project 2-3 years ago, AI was already booming at the time, however voice AI agents were still very early. I loved my proof of concept at the time, but wasn't quite happy with it. I recently had the desire to check out the tech again, and know many of you will be interested. Interviews are speech to speech with OpenAI's gpt-realtime-2.1 over WebRTC. This model is... expensive, and because of that, I have to add some amount of restrictions, conversations are tied to a authenticated Clerk user id. I…

Hey HN, Michael and Scott here. We’re open-sourcing an interactive murder mystery featuring LLM-driven character agents. Solve the mystery by finding clues, taking notes, and interrogating agents. They all have distinct motives, personality, and can impact the game in different ways (attacking you, running away, etc). Try it out, it’s pretty fun! We’re also open-sourcing the framework that we used to make and refine the agents. The goal is to create an intuitive interface for storytellers to create, debug, and test game agents. We then take those game agents and expose an API beyond just…

What: So I built this small (and ofc free) web-based interactive game where folks solve a murder mystery while learning MongoDB commands and concepts. It combines a fun storyline with practical lessons to help you practice querying and navigating data. It’s not a full tutorial—more like a self-directed exercise with an optional walkthrough to guide you. Motivation: Over the holidays, I wanted to teach MongoDB basics to my 8th-grade nephew in an interactive and exciting way. I was inspired by the popular SQL Murder Mystery and thought, “Why not create something similar for MongoDB?” I tested…
