What is My Pocket Universe?

My Pocket Universe is an AI writing platform for storytelling, AI roleplay, and worldbuilding. It uses persistent memory AI so characters remember past interactions, worlds evolve over time, and stories never reset.

How is My Pocket Universe different from ChatGPT?

Unlike ChatGPT, My Pocket Universe uses a persistent memory AI system that tracks character relationships, emotional states, and world events across every session. It is purpose-built for storytelling and AI roleplay — not general chat.

Does the AI remember my characters and story?

Yes. My Pocket Universe is built around an AI that remembers conversations, character traits, emotional history, and world events across sessions. Your AI writing assistant retains full continuity so your story never has to start over.

Is My Pocket Universe free to use?

Yes — you can start for free with no credit card required. Free users get access to the Explorer tier. Paid tiers unlock advanced AI engines including the P4 Living World Engine.
