ego
Character AI + Roblox :persistent, sapient AI characters in 3D worlds
If you are part of ego (or you are a YC founder who looks at ego and thinks that is the kind of business I run), you probably do not have time for a six-month SEO agency contract. Seoable was built for that. Audit your site, queue 100 ready-to-publish posts, and run it all from your AI assistant.
About ego
Ego AI is building Character AI + Roblox. Our conviction is that 3D embodiment, shared activities in games and AI imbued with human-like personalities will solve the existing problems of low-stakes, shallow and generic interactions that impact retention in consumer AI chat experiences. We’re fine-tuning a foundation model for characters to behave in human-like ways—indistinguishable from real people—and building a UGC platform around it to allow users to create, experience and form meaningful connections & mutual stories with these AI characters. On our platform, simworld, users will be able place the characters in a Stardew Valley style simulated town, where the AI characters will live, work and play, leading rich internal lives. Users who deepen bonds with these AI character friends can invite them out with them to Discord, Minecraft or even a Netflix-n-chill session. Our Character engine, ego AI, built on top of Unreal, will allow users to create, deploy and even monetize their characters across any surface that supports our CCProtocol. The first use case for our characters will likely be DnD-style roleplay, Minecraft RP, and Twitch streaming. Characters will always live and exist in Simtowns with other AIs (and humans) where they will all lead varied internal lives replete with conflict, danger, opportunity, and love…just like humans in the real world! During YC, we used our engine to build TownWorld - a 3D interactive Twitch live stream of the Stanford generative agents paper (https://www.twitch.tv/townworld). To the best of our knowledge, it's the first ever AI 3D simulation of a small town in real time YC Launch - https://www.ycombinator.com/launches/KeD-ego-an-ai-native-3d-simulation-engine-getting-us-closer-to-the-matrix-one-pixel-at-a-time Demo video: https://docsend.com/view/mzf6i7kiwkkgg669 AI 3D TownWorld video: https://docsend.com/view/ig6t2shuz26z7wha
