Durable agentic memory, encrypted at rest.

Your AI agent forgets you the moment the session ends. Compartment ends that. With Compartment, your AI agent gets better with experience: it keeps every decision, preference and detail you give it, permanently, encrypted, on your own computer. Hermes, Claude, OpenClaw and other AI Agents can install in one command. One fully-transferable memory store is shared simultaneously by all agents on the computer. 100% offline: no network, no API key, no cloud account, no telemetry. The embedding model ships inside the package, and a full search returns in about 12 ms, beating the round-trip a hosted memory charges you for. Every byte at rest is AEAD-encrypted, the embedding vectors included, and only your passphrase opens it.

Unlike other agentic memory, we offer an option to start off with memory - 6,718 curated facts seeded at install: the physical constants and unit conversions, 800+ hardware facts with real specs (Apple silicon, PCs, CPUs and GPUs, phones, game consoles, Raspberry Pi, storage, displays, connectors) to provide a map of computer geography, operating system versions and release names, network ports and HTTP, file signatures, character encodings, shell and Unix internals, git, regex, SQL and hashing, ISO country, currency and time codes, and more. Allows an offline agent to operate better without internet, and an online agent to operate faster and more accurately.

More secure, by construction. Every byte at rest is authenticated-encrypted, the embedding vectors included (most tools leave those in the clear, and vectors can be inverted back toward text). Deletion is cryptographic: destroy the record's key and it is gone, unrecoverable. Tampering is detected, history is hash-chained, and the vault locks itself on restart or power loss. It runs fully offline: a runtime guard aborts on any network attempt, and CI proves it on three operating systems.

Not one step harder. One command installs it, creates the vault, and wires your agent. No API key, no cloud account, no daemon. Unlock when you want to use it; lock when you want it closed. By default an unlock stays open for weeks (until restart or you lock it), like any app you leave running. The security is free at the point of use because it falls out of the architecture, not out of your patience: keeping plaintext off disk forces the index into RAM, and a RAM-resident index is also the fastest one there is. Secure and fast are the same choice here, and neither costs you a configuration step.

Install

One line install, works on all operating systems.

pip install compartment && compartment init

Then connect it to the agent you use:

compartment integrate claude

claude, hermes and openclaw are the three auto-connect targets. Each one also gets the /compartmentalize skill installed into its own skills directory.
