    Hey HN — I've been working on creating small games with LLMs for the past year or two and found that one thing they have been bad at generally is creating story worlds — they tend to generate clusters of similar characters that aren't intrinsically linked to each other. I was thinking about this and remembered the semi-famous alien invasion political compass meme: https://www.reddit.com/r/PoliticalCompassMemes/comments/ktyq... I really liked how that format enforces the need to fill out all parts of the alignment chart, giving you a rich diversity of characters.…

    Hi I've created a text-based RPG game in which you can experience different adventures and play interesting characters while the AI acts as a real time DM/story teller. There are multiple ways to interact with AI: 1) Input free will move 2) Input default move (affects resources) 3) Post a question to DM Also one more cool feature is that you can create your own adventure via simple form. Add scenes, add characters and make it public so other players are able to test it. I also plan to have 'competetive' side where players will pay some small fee to creators in crypto depending on…

    Hey everyone, I built this project because I always wanted to try playing D&D but couldn’t find a group of friends or a DM to play with. It’s still early stages and not meant to be a complete replacement for real DMs or IRL sessions, but it’s a good way to dip your toes into DnD or to play on your phone between your IRL sessions. I tried playing D&D with ChatGPT but the overall experience was lacking, so I built this site & Discord bot that has a character sheet tool, better memory management, support for multiplayer, and automatic tracking for things like spells, HP, and encounters. Try it…

    This has been my secret pleasure for the past four years. Ever since I started playing D&D during the pandemic, I discovered my love for role playing and storytelling, but Beyond just wasn't cutting it for me. I wanted to make my own personal character creator and tracker that I could use for my games, so I set out to build Dwarven Academy (https://dwarven.academy/) and after two years of learning I decided to rebuild it all from the ground up, so The Elder Dragon's Tavern was born. Try it out at https://elderdragonstavern.com/ This is an app to build and track…

    Most book summaries on the internet are not detailed enough. In this project, I've tried to create detailed chapter-level summaries that retain a greater level of detail and vocabulary of the original. The aspiration is for these summaries to be a credible alternative to reading the books themselves. Website hosted on Vercel: https://book-summary-pro.vercel.app/ The code behind the project on GitHub: https://github.com/cosmic-glitch/book-summarizer Request additional books:…

    Hi HN! We are Tiago and Patrik. We're building an application to improve the process of taking notes and personal knowledge management. We met through the YC Co-Founder matching platform and we had a common interest of being heavy book readers. We also suffered from the same problem: using notes from books we read. The biggest problems with note-taking are: - Notes in physical books are hard to digitize without introducing significant friction. - People rarely revisit their notes due to poor organization, leading to notes being dumped into files that quickly become gigantic, unusable, and…

    I wanted to create an LLM game benchmark that put this generation of frontier LLMs' top skill, coding, on full display. Ten years ago, a team released a game called Screeps. It was described as an "MMO RTS sandbox for programmers." In Screeps, human players write javascript strategies that get executed in the game's environment. The Screeps paradigm, writing code and having it execute in a real-time game environment, is well suited for an LLM benchmark. Drawing on a version of the Screeps open source API, LLM Skirmish pits LLMs head-to-head in a series of 1v1 real-time strategy games.
