Lossless-memory - Personal AI memory that never summarizes
Show HN: Lossless-memory – a personal AI memory that never summarizes
Lossless-memory is a local, file-based long-term memory layer for personal AI assistants that refuses to summarize. It stores every conversation line verbatim with timestamps, builds a Temporal Backbone for time-first search, and injects a tiny 'where are we now' index (LLL) into the model's context every turn. Built for one person and one AI on one machine, it solves the forgetting problem by keeping raw logs as the source of truth. Runs daily since July 2026, with JSONL logs and SQLite indexes that can be rebuilt anytime.
Summarization is the forgetting: the exact words, the time of night, the way something was said — the parts that make a memory feel like it belongs to someone — are the first things a summary drops. So this system refuses to summarize.

Is the date really useful? Usually I want the AI to remember rules, like "always do X before committing Y" and a timestamp doesn't change anything there.

Have you thought about using llm-wiki? It's pretty powerful and works well.

It may seem useful at first, but eventually you'll hit a wall where this doesn't work, and you have to add another memory technique. Eventually you end up with a complex multi-layered system, because what people want by "memory" is actually 10 different things which all need their own solution.
