What is Localmem

Persistent context, without giving up your privacy

🔒
100% local & private
Memories live in plain files on your Mac. Nothing ever leaves the device — no cloud, no accounts.
🗂️
Cross-project by design
Recall context across every conversation and repo. One shared memory, wherever your agent works.
🔌
Speaks MCP
A native Model Context Protocol server any compatible agent can connect to in seconds.
🛡️
Per-memory access control
Grant or revoke what each agent can read and write, memory by memory.
📜
Full audit log
Every store and recall is logged locally, so you always know what your agents remember.
⌘
App + CLI
A polished macOS app for browsing memories, plus a fast CLI for scripting and automation.
📄
Import from your files
Pick Text, Markdown, or PDF files and Localmem pulls out the key facts on your Mac, turning them into memories — via Apple Intelligence, or a coding agent you already use. Every fact is verified against the source document before it's stored, and each file shows exactly what was kept vs dropped. You choose every file; nothing is scanned automatically.
📦
Import & export
Move memories in and out as plain JSON — portable backups and one-click transfer between Macs, no proprietary tooling.

How it works

Three steps to lasting memory

1
Install & connect
Download the app or run the CLI, then point your agent at the local MCP endpoint.
2
Agents store & recall
Your agents write and search memories automatically as they work — no manual bookkeeping. Or seed the vault by importing your files.
3
You stay in control
Browse, edit, and revoke memories anytime from the app. Your data, your rules.

One memory, every agent
