memoir

Sync AI memory across every tool and every machine — end-to-end encrypted. Free.

npx memoir-cli

One command. No install, no config, no API keys. Claude Code on your Mac, Cursor on your laptop, Copilot at the office — one memory follows you across every tool and every machine, encrypted with a key only you hold. memoir's servers literally can't read it.

What it does

Your coding tools are starting to remember you — Claude Code, Cursor, and Copilot all ship built-in memory now. But that memory is trapped: one tool, one machine, stored in plaintext. Switch from Cursor to Claude Code, or open a different laptop, and your AI is a stranger again.

memoir is the MCP memory server that breaks it out. One memory, shared across every tool and synced to every machine — encrypted client-side, so even memoir's servers can't read it. Your AI searches, saves, and recalls context automatically, everywhere you work.

you: how does auth work in this project?

  memoir_recall("auth setup architecture")
  Found 3 memories matching "auth"

claude: Based on your previous sessions: this project uses JWT auth
  with refresh tokens, the middleware is in src/middleware/auth.ts,
  and you chose Zustand over Redux for auth state (decided March 12).

No re-explaining. memoir remembered.

How it's different

Native memory and the other memory tools each give you part of this. memoir is the only one that gives you all of it:

Native memory is locked to one tool on one machine. The others keep your memory in plaintext, or put cross-machine sync behind a paywall. memoir is the only one that does all three — every tool, every machine, encrypted under a key only you hold — for free. (Based on public docs, June 2026.)

Quick start

npx memoir-cli

That's it. memoir detects your AI tools, configures MCP, and activates memory. No global install needed.

Your AI gets 14 memory tools:

Why memoir

Your AI forgets everything between sessions. You re-explain your codebase, your conventions, your decisions — every time.

memoir fixes that. Tell Claude something once and Cursor knows it too — your memory syncs between tools, backs up to the cloud, and restores on any machine. When it piles up, memoir consolidate cleans house: finds duplicates, flags stale context, and can use AI to merge and prune.

11 tools supported: Claude Code, Cursor, Windsurf, Gemini CLI, GitHub Copilot, OpenAI Codex, ChatGPT, Aider, Zed, Cline, Continue.dev.

Sync across machines

memoir push       # back up AI memory + workspace + session
memoir restore -y # restore on any machine

Push syncs AI memory, cursorrules, session context, workspace (git repos + uncommitted work), and project configs. E2E encrypted with AES-256-GCM.

Translate between AI tools

memoir migrate --from chatgpt --to claude
# AI-powered — rewrites conventions, not copy-paste

memoir migrate --from chatgpt --to all
# Translate to every tool at once

Consolidate memories

memoir consolidate          # scan for duplicates, stale files, bloat
memoir consolidate --smart  # AI-powered analysis (finds contradictions + merge candidates)
memoir consolidate --apply  # interactively clean up

Over time, memories pile up across tools. Consolidate finds exact and near-duplicates, flags files untouched for 60+ days, and catches contradictions where you told Claude one thing and Cursor another. With --smart, Gemini Flash does a semantic pass and suggests intelligent merges.

Cloud sync

memoir login
memoir cloud push      # encrypted cloud backup
memoir cloud restore   # restore from any version
memoir history         # view backup versions
memoir share           # create encrypted shareable link

All Commands

Security

• E2E encryption — AES-256-GCM with scrypt key derivation

• Secret scanning — API keys, tokens, passwords auto-redacted before sync

• Local MCP server — runs on your machine, no data sent externally

• Zero-knowledge cloud — encrypted before upload
