OptMem: Persistent Memory for AI Agents
OptMem is a 426 token prompt block and a standalone python script that provides persistent memory for AI agents.
OptMem is a persistent memory system for AI agents. It’s a 426 token system prompt and a single standalone python script that saves memories to a local binary tree. Installing OptMem takes only 1 curl command, and integrating it into your code requires adding just 1 prompt block to your CLAUDE.md or AGENTS.md file. This tool became viral due to its ability to address a fundamental pain point (loss of context after each session) while providing a simple and universal solution.
Why a vibe-coder should care
Your AI agent will never forget what happened before — no matter how many times they change models or reset context. Once you share information with them, they’ll remember forever.
