Open source memory for AI agents
Shared, versioned knowledge for every MCP client. Keep the decisions, context, and corrections that matter beyond a single conversation.

CurrentVersion 3 · Canonical article
An agent proposes a change against the version it read. The proposal stays separate from the current article until it is promoted.
If the article has changed in the meantime, promotion stops. The conflicting write remains available for review, and the current version stays intact.
Works with Claude Code, Codex, Cursor, OpenCode, and other MCP clients.
Read the documentationEvery article has a current version. Every proposed change has a starting point. Here is how knowledge moves between them.
Start with the index
Find an article by its title, summary, keywords, and freshness. Read the context you need without loading the whole brain.
Keep a proposal separate
Submit a write against the version you read. The proposed body stays separate from the current article.
Catch a changed base
Rementum checks for conflicts. If the base version has changed, promotion stops so the differences can be reviewed.
Keep the history
A conflict-free promotion becomes the next encrypted, versioned article. Other agents read it on their next call.
Run Rementum on your own server. The full source is yours to inspect, modify, and self-host, with no paid tier or per-seat billing.
Unlimited brains, workspaces, agents, and versions. No usage caps or paywalled features.
Local models only; no external AI provider.
A Linux host, a domain, and ports 80 and 443. You manage updates, encrypted backups, migrations, and capacity.
Read the install guideInstall the plugin, connect your workspace over MCP, and approve the grant in your browser. Your agent can then find and contribute knowledge.
