PastPortal: Chat Suite Free Edition is your gateway to an immersive conversational experience with AI-simulated public figures from the past and imaginative realms.

Designed as a standalone application, PastPortal offers the perfect blend of entertainment and unpredictability, providing an unrivaled platform to interact with AI personas in a totally private, non-tracked environment.

Key Features of the Free Edition

  • AI-Powered Conversation: Engage in dialogues with a limited range of AI-simulated personas.
  • Offline Use: Experience uninterrupted, latency-free usage with our offline application.
  • Privacy Protection: Rest assured, we prioritize your privacy. No data tracking or surveillance is implemented.

Behind the Scenes

The Technology

The application/game has been developed using Unity and C#. For AI modeling, we leverage the cutting-edge Llama 2 and llama.cpp libraries under the MIT License, which respect privacy and don't require an internet connection. This combination of technologies allows us to provide engaging, AI-powered conversations offline, all while ensuring the utmost respect for user privacy.

The Journey

  • Initial Development: A solid foundation has been developed, focusing on key features such as AI-powered conversation, offline use, privacy protection, and a selection of pre-built lively personas.
  • Continuous Improvement: The journey doesn't stop at launch. Existing features will be enhanced and new ones introduced where possible, based on user feedback. An in-engine persona creation feature is already in the pipeline and should be released very soon.
  • UI/UX Refinement: Users are at the heart of this product. Feedback will play a crucial role in shaping and refining the user interface and overall user experience, ensuring PastPortal: Chat Suite remains intuitive and enjoyable to use.

Tailor Your Experience

The Free edition of PastPortal comes with limited personas and does not have the ability to load custom personas or receive future updates. It is provided as-is with no dedicated support. If you enjoy the experience and crave more features, consider upgrading to the Paid edition. Check out the full version here for a greatly expanded selection of personas, the ability to load in your own customized personas, and free future updates.
