About LISA Core

LISA Core is a privacy-focused browser extension designed for users who frequently engage with AI conversations across various platforms. It leverages advanced semantic compression technology to efficiently store and manage chat data locally, achieving compression ratios of up to 100:1 without losing the core meaning or context of the conversations. This ensures that users can preserve important dialogue history without relying on cloud storage or risking data leaks, making it ideal for privacy-conscious individuals and professionals who need to retain AI interactions securely. Its seamless integration into the browser allows for quick capture and compression of conversations, transforming how users log, review, and revisit their AI exchanges with minimal storage impact. LISA Core stands out by combining cutting-edge semantic compression with a zero-cloud, local-first approach, ensuring user data remains private and accessible only on their device.
