Show HN: AI memory with biological decay (52% recall)

YourMemory Persistent memory for AI agents — built on the science of how humans remember.

The Problem

Every session, your AI assistant starts from zero. It asks the same questions, forgets your preferences, re-learns your stack. There is no memory between conversations.

YourMemory fixes that. It gives AI agents a persistent memory layer that works the way human memory does — important things stick, forgotten things fade, outdated facts get replaced automatically. Two commands to install, zero infrastructure required.

How Well Does It Work?

Tested on LoCoMo-10 — 1,534 QA pairs across 10 multi-session conversations.

System Recall@5 95% CI YourMemory (BM25 + vector + graph + decay) 59% 56–61% Zep Cloud 28% 26–30%

2× better recall than Zep Cloud on the same benchmark.
