Lore▲130I built Lore because I kept losing knowledge — curl commands, quick notes from standups, and that one thing I told myself I'd remember. It lives in the system tray, a global shortcut pops it up, you type naturally, and it stores or retrieves automatically. Everything runs locally via Ollama + LanceDB — no cloud, no API keys. It classifies your input (thought, question, todo, instruction) and uses a RAG pipeline to answer recall queries from your own stored context. It's free and open source under MIT license, and even though its in very early version me and my friends have been using it for…

I figured I needed to work on my coding skills before building the next groundbreaking AI app, so I started working on this free tool site. Its basically just an aggregation of various commonly used calculators and unit convertors. Link: https://www.calcverse.live Tech Stack: Next, React, Typescript, shadcn UI, Tailwind CSS Would greatly appreciate your feedback on the UI/UX and accessibilty. I struggled the most with navigation. I've added a search box, a sidebar, breadcrumbs and pages with grids of cards leading to the respective calculator or unit convertor, but not sure if…

Most games have limits. You can only use preset features, need coding for customization & adding mods, require expensive extra devices. We wanted to remove those barriers. That’s why we are building space zero—a browser based 3D world powered by AI. We plan to build players can freely mix items to generate unexpected creations with unique properties and sounds. Also the world itself is dynamically generated, evolving endlessly. I uploaded a demo version I’ve been working on for the past month! I hope to get any feedbacks or comments :)

Hi HN, I'm Kai Wang, one of the creators of Yuanzai World. We built a simulation engine (currently on iOS & Android) that allows the community to create and share text adventures populated by multiple LLM-based agents. Unlike standard chatbots, our focus is on community co-creation—users define the worldviews, and our agents (with persistent memory and social relationships) bring them to life. The cool part: We implemented a system we call "World-Line Divergence" (inspired by visual novels like Steins;Gate). Usually, AI RPGs feel random or infinite loop. We built a state machine that tracks…

Hey HN, After hours of re-watching Brandon’s creative writing BYU lectures[1], we converted his ideas into a framework to rapidly iterate and build sci-fi fantasy worlds. The app is divided into 3 sections: - World: To create a unique magic system intertwined with distinct physical and cultural phenomena - Characters: To create character arcs and give them unique traits that evolve over time - Plot: To weave a series of events in this world following the character arc We are newbie devs, any suggestions on the app improvements and usability would be great! The idea is to capture the essence…

Hi HN! I’ve spent the summer of the past 2 years building The Atlas, a procedural universe simulator that generates 1 sextillion galaxies (10²¹) from a single mathematical seed. Think No Man’s Sky meets theoretical physics, but running entirely in your browser. Everything is purely deterministic, the universe is calculated from SHA-256 hashed seeds using the golden ratio as primordial constant. There’s no database, no pre-saved data, just pure math. Time itself is treated as a coordinate, so the universe exists as a 4D structure where any moment can be computed on demand. Shut it down for…

While summarizing videos (I'm the Eightify founder), I've been secretly working on an AI-generated encyclopedia, and here's why. I found myself thinking a lot about AI and content. Now we have knowledge (think Wikipedia) and intelligence (LLMs). They will both significantly improve soon. What we lack is *a knowledge interface for humans*. What I don't like about current interfaces: - ChatGPT: to get an answer how I want it, I need to craft a perfect prompt - Google: need to spend time avoiding affiliates and unreliable sources - Wiki: great, but boring to read, too much information What I…
