Show HN: Mneme – Open-protocol AI memory that lives on your device (github.com)

Mneme, a new open-protocol AI memory system, has launched in public beta, focusing on user sovereignty and local-first design. Unlike existing models that store data on proprietary servers (like Mem0, ChatGPT Memory, and others), Mneme allows users to maintain total control over their data, storing it locally on their devices while supporting end-to-end encryption and an open protocol applicable across various AI applications. This structural inversion is significant as it empowers users to own their memory, avoiding vendor lock-in and ensuring data integrity. Technical benchmarks indicate that while Mneme is competitive with current memory systems in semantic understanding, it has a stark advantage in strict factual recall, showing a 62.4% match compared to Mem0's 8.5%. This performance underscores Mneme's architecture, which retains the original source language, enabling easier citation, compliance auditing, and reproducibility of memories. The system offers a range of functionalities, such as on-device embeddings and multi-device synchronization, all while emphasizing privacy and usability, marking a shift in how AI memory can be managed by end-users.
