DreamGen is an AI-powered storytelling platform specialising in interactive fiction and roleplay. Users can create their own scenarios, characters, and fictional environments, then interact with AI-generated characters or use the platform to write longer stories. It offers multiple AI models, adjustable context windows, and a credit-based usage system. Its scenario-building tools allow writers to establish character personalities, relationships, settings, and story directions. DreamGen is designed for creative freedom, with particular emphasis on immersive narratives and roleplay rather than conventional business writing.
