GitHub - aru-labs/lossless-memory: Lossless long-term memory for a personal AI
Personal AI keeps every conversation line with timestamps, no summaries.
In brief
Personal AI keeps every conversation line with timestamps, no summaries. A personal AI system stores raw conversation logs with timestamps to avoid forgetting details, working since June 2026. Originally reported by GitHub.
What it does
Stores raw conversation logs without summarization.
“Never summarize, keep every line, put a timestamp on everything”
Why it matters
Prevents forgetting what was actually said and when.
“The thing that matters most to a person who talks to the same ai every day: what was actually said, and when”
How it works
Timestamps every record and searches by time first.
“Search by time first, words second”
The Temporal Backbone
Uses time as the primary search axis.
“Time is not metadata here; it is the primary axis”
LLL index
Tracks current topic with human-written markers.
“The ai reads it; the human writes it”
Real operation
Has run since June 2026 for one user.
“This implementation has been running every day since 2026-07”
Design pillars
No summaries, raw logs, and time-based search.
“It is not a summarizer. There is deliberately no summarization step anywhere in the pipeline”
Why it exists
Fixes ai forgetting conversations over time.
“This was built for one person who has talked to ai assistants every day for years and watched each of them forget”
How it scales
Reindexes every 10 minutes without downtime.
“A small daemon reindexes incrementally on a fixed interval (default: every 10 minutes)”
Limitations
Only works for one person and one machine.
“Designed for one person and one ai, running on one machine. No server, no cloud”
What it's not
Not a vector database or benchmark system.
“It is not a vector database wrapper. Semantic search is the last resort here, not the first”
At a glance
A personal AI system stores raw conversation logs with timestamps to avoid forgetting details, working since June 2026.
