Question: Is there a service that allows me to play text-based RPGs with customizable AI personalities and no data logging?

If you're looking for a service that lets you play text-based RPGs with customizable AI personalities and no data logging, Backyard AI is a great option. It's a text adventure experience with AI characters, both online and offline, and the service prioritizes privacy, storing data locally and encrypting it at rest, and it doesn't log or share data. With a variety of language models and a free tier, it's a good foundation for role-playing and a safe place to experiment.

Another option is Layla, a private offline AI chatbot that runs on devices with no internet connection. It's customizable with settings and personalities for more engaging conversations and roleplay. Layla uses large language models to learn from you, and it can generate stories and remind you of tasks, all while protecting your privacy and security with weekly updates.

If you like a community experience, Saga marries old-school RPG flavor with modern technology. It's customizable, with settings and conversational dialogue with AI characters. AI-generated illustrations and a community forum add flavor to the role-playing experience, and it's easy to use and understand. Saga's customization and community interaction is great for people who like collaborative storytelling.

Last, AI Adventure is an open-source platform that lets you create and share your own custom RPG adventures with powerful editing tools. It's customizable in many ways and generates story, images and audio on the fly. With features like community-created adventures and easy transaction integration, AI Adventure offers a fresh and dynamic storytelling experience.
