Building an Interactive Hacker News Simulator

I created a fun project: an interactive Hacker News (HN) Simulator that mimics real HN interactions. Users can submit text posts or links, which are instantly responded to by AI-generated comments created by large language models (LLMs).

The best way to try it is to visit the submission page at https://news.ysimulator.run/submit. No account is needed to post. When a post is made, the system generates responses based on various comment archetypes, moods, and styles, making the interaction feel realistic. The AI commenters reply directly to your posts or links, aiming to emulate typical HN discussion flow.

Developed using Node.js, Express, and Postgres, the simulation runs on Replicate to handle AI inference. Thanks to Replicate’s free credits, the project can generate comments efficiently.

The most intriguing aspect is how comments are created. Detailed info about the comment system, including archetypes and moods, can be explored at https://news.ysimulator.run/comments.html.

I hope users enjoy experimenting with the simulator as much as I enjoyed building it.
