README
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:
| Cross-tool | Cross-machine sync | Zero-knowledge encrypted | |
|---|---|---|---|
| memoir | ✅ | ✅ free | ✅ |
| Claude Code / Cursor native | ❌ one tool | ❌ one machine | ❌ |
| claude-mem | ✅ | ❌ local only | ❌ |
| basic-memory | ✅ | 💲 paid cloud | ❌ |
| mem0 / OpenMemory | ✅ | 💲 paid cloud | ❌ |
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:
| MCP Tool | What it does |
|---|---|
memoir_recall |
Search across all your AI memories |
memoir_remember |
Save context for future sessions |
memoir_list |
Browse all memory files by tool |
memoir_read |
Read a specific memory in full |
memoir_consolidate |
Analyze memories for duplicates, staleness, and bloat |
memoir_status |
See which AI tools are detected |
memoir_profiles |
Switch between work/personal |
memoir_set_goal |
Set the current session goal (pinned into CLAUDE.md) |
memoir_add_next |
Add a next action to the current session |
memoir_complete_next |
Mark a next action as done |
memoir_note |
Record a decision with its rationale |
memoir_ask |
Capture an open question for later |
memoir_session |
Show goals, next actions, decisions, and recent sessions |
memoir_why |
Look up why a past decision was made |
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
