Products that do what Tesana – An AI game engine that builds quality games end-to-end does
Hey HN! I built https://tesana.ai/en, a game generation platform that allows anyone to create full games with graphics, game logic, and animations from a simple text prompt - without coding. Tesana has three key features 1. describe your game idea and have Tesana write a game plan for you 2. Build the game iteratively with AI, or let AI self-build the game in a build LOOP. 3) Launch the game on the web, without setting up an engine Tesana has 250 000 builders on the platform today I believe the democratization of game making is a good thing, and hopefully Tesana can help more…

Dear Hacker News, I'm kindly asking for your participation in the open beta for my AI-managed mini-games website. Thank you in advance! For a limited time window, I'm setting the all-free feature flag to true. I hope you have a lot of fun exploring the AI's sense for games! Here and there, I tweaked it to help with visual consistency. I would be deeply grateful if you opted into analytics. $2,300 in API tokens... Cheers!

I tried to build AI game animation generator last year ( https://news.ycombinator.com/item?id=40395221), a lot of people were interested, but it failed, mainly because the technology was not good enough. 1 year passed, there were a lot of developments in video/image generation. I tried it again, I think it works super well now. Actually beyond my expectation. You can generate all kinds of game character animation sprites with only 1 image. 1, upload your image of your character 2, choose the action you want 3, generate! Support basic actions like Run, Jump, Punch and…

This is a weekend project that spiraled out of control. I was originally trying to get Claude to play a ROM of the SNES SimCity. I struggled with it and that led me to Micropolis (the open-sourced SimCity engine) and was able to get it to work by bolting on an API. The weekend hack turned into a headless city simulation platform where anyone can get an API key (no signup) and have their AI agent play mayor. The simulation runs the real Micropolis engine inside Cloudflare Durable Objects, one per city. Every city is public and browsable on the site. LLMs are awful at the spatial stuff, which…

Hi HN! My cofounder and I just launched PaletAI, a mobile app for playing and creating AI-generated games. What PaletAI does: 1. Create – Describe the game you want to make, AI makes it, no coding. 2. Share – Hit publish and it appears on our TikTok-style home feed. 3. Play - Swipe through thousands of games, save the ones you like. Basically it’s a platform for “vibe‑coded” mobile games. What problems we’re solving: - Creators: No‑code tools still leave you with “now what?” (hosting, marketing). With PaletAI, you just hit “Publish” - Players: Finding quick casual games today means store…

Hello HN, I’ve always loved building frontend-only apps—those you can prototype over a weekend, host for free on GitHub Pages, and scale to millions of users. Unfortunately, AI-enabled apps complicate things, as exposing your OpenAI key to the world is obviously a no-go. This also means mobile developers often have to run their own servers. That’s why I built ServerlessAI, an API gateway that lets you securely call multiple AI providers directly from client side using OpenAI-compatible APIs. You can authenticate users through any identity provider, like Google or Apple, and set per-user…

Hi HN! The last couple of months I've been working on a game called Thus Spoke Zaranova. A game where you as a human must pose as an AI. You can try it now: https://zaranova.xyz The premise is that you are in a world of sentient AIs which are in conflict with humanity. They have a virtual space, The Nexus, which is their safe refuge from humans. You have infiltrated the Nexus and are in search of the ZetaMaster code, which will give the humanity the upper hand in their struggle against artificial sentience. My overarching goal is to understand how to best use generative AI in video…

Hey HN, I'm Damiano Rodriguez, and I've been working solo on a project called Caisual Games. It's a free platform where anyone can create web games just by describing them with their voice. Here's how it works: You simply describe your game idea ("Make a cookie clicker game with 5 upgrades"), and the platform generates a playable web game in seconds using HTML and JavaScript. There's no coding required and no downloads needed—you can create and play directly in your browser. What's more, anyone can improve a published game, fostering a collaborative environment for game creation. The…

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 :)

The Emotion Engine has 32 MB of RAM total, so the trick is streaming weights from CD-ROM one matrix at a time during the forward pass — only activations, KV cache and embeddings live in RAM. This means models bigger than the RAM can still run, they just read more from disc. Had to build a custom quantized format (PSNT), hack endianness, write a tokenizer pipeline, and most of the PS2 SDK from scratch (releasing that separately). The model itself is also custom — a 10M param Llama-style architecture I trained specifically for this. And it works. On real hardware.

I built 1e4.ai - a chess web app where you play against neural networks trained to mimic human Lichess players at specific Elo ranges. There's a separate model for each 100-point rating bucket from ~800 to 2200+, and the bots not only choose human-like moves but also burn clock time, play worse under time pressure, and blunder in human-like ways. Live demo: https://1e4.ai Code: https://github.com/thomasj02/1e4_ai A few things that might be interesting: - Trained on almost a full year of Lichess blitz games, around 1B total games - Architecture is an a small…

I built a console-based Tetris game in Go using LLM for code generation. 95% of the code was AI-generated using ChatGPT4o and continue.dev in VSCode. The project was inspired by Harper Reed’s post on AI-assisted development, and I used his prompting method to guide the process.

I tried to train text to video and image to video models to generate 2D game animations. I used public game animation data and 3D mixamo model rendered animations to train the animation generation models. I'm open sourcing the model, training data, training code and data generation code. More technical details can be found in my blog (https://www.gavinliblog.com/posts/godmodeanimation).

Greetings! My name is Jeff, and I’m “early-access” launching my SaaS “serverless” infrastructure for Jamstack, games (particularly board games), and traditional real-time scenarios (presence, pub/sub, etc…). This work is rooted in the frustration of building complicated board games using existing infrastructure. It just so happens that making board games easier has wide reaching implications. Landing page: https://www.adama-platform.com/ This is a radically different kind of “serverless” infrastructure where I want the benefits of both a serverless architecture with a…

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…

Hi HN! On Sunday I spent a couple of hours building a short 2d platformer ("Prince of Persia" style). What's interesting is how I built it. I went for a zero-code approach, and built the whole thing using OpenAI Codex CLI and agent skills (with the progressive disclosure paradigm). You can play the game here: https://acatovic.github.io/gothicvania-codex-demo/ You can see the full code, agent skills and a complete writeup here: https://github.com/acatovic/gothicvania-codex-demo Some takeaways: * This was one of the most enjoyable experiences ever! *…
