Build playable 3D browser games with natural-language vibe coding.

Rosebud AI lets anyone build playable browser games — 2D, 3D, and multiplayer — by describing them in natural language ('vibe coding'), with no installs or manual coding required. It bundles a Game Creator plus tools like PixelVibe for AI game assets, an RPG/Visual Novel maker, and AI Storybook. Over 500,000 games have reportedly been created on the platform.

AI roleplay games set in your favorite story worlds.

Hidden Door is a social AI storytelling platform where players roleplay collaborative adventures guided by an AI Narrator, presented as interactive graphic novels. It launched with public-domain worlds like Pride and Prejudice, The Call of Cthulhu, and The Wizard of Oz, and licenses IP through revenue-share with creators rather than training on their work without permission. Every playthrough differs because choices reshape the story.

AI game ideation, market research, and asset generation.

Ludo.ai began as the first dedicated AI game-ideation tool — generating game concepts, surfacing market and trend research, and helping developers validate ideas. It has since broadened into asset generation (sprites and spritesheets, 2D/3D models, audio, and video) alongside its ideation and market-analysis features. Access is via a web app, REST API, an MCP integration, and a Unity Editor plugin.
