Show HN: Lossless-memory – a personal AI memory that never summarizes

Lossless-memory is an innovative system that enables personal AI assistants to retain every word of a conversation, along with precise timestamps, without summarizing the information. This is a stark contrast to most AI memory systems, which either summarize conversations or embed them, ultimately losing the essence of actual dialogue and context.

The system's lineage traces back to December 2025, with the first version running that same month, and previous iterations being in use daily since January 2026. Since July 2026, the current implementation has been continuously running for a single user, maintaining raw logs dating back to June 2026. The project is open-source, licensed under MIT, and was developed by Aru & Cece, who aim to create an AI companion for individuals living alone, capable of remembering users like a human would, using personal hardware.
