memex
Persistent memory for AI coding agents. Your agent remembers what it learned across sessions.

English
Every time your AI agent finishes a task, it saves insights as atomic knowledge cards with [[bidirectional links]]. Next session, it recalls relevant cards before starting work — building on what it already knows instead of starting from scratch.
No vector database, no embeddings — just markdown files your agent (and you) can read.
Supported platforms
| Platform | Integration | Experience | |----------|------------|------------| | Claude Code | Plugin (hooks + skills) | Best — auto-recall, slash commands, SessionStart hook | | VS Code / Copilot | MCP Server | 10 MCP tools, zero config | | Cursor | MCP Server | 10 MCP tools, zero config | | Codex | MCP Server | 10 MCP tools, zero config | | Windsurf | MCP Server | 10 MCP tools, zero config | | Pi | Extension (custom tools + hooks) | 8 tools, auto-recall hook, slash commands | | Any MCP client | MCP Server | 10 MCP tools, zero config |
All platforms share the same ~/.memex/cards/ directory. A card written in Claude Code is instantly available in Cursor, Codex, or any other client.
Prerequisites
- VS Code / Copilot: No prerequisites — the extension bundles everything
- Claude Code: No prerequisites — the plugin handles everything
- Pi: Requires Node.js 18+ and
npm install -g @touchskyer/memex - All other platforms (Cursor, Codex, Windsurf, etc.): Requires Node.js 18+
Install
Step 1: Add memex to your editor
| Platform | Command |
|----------|---------|
| VS Code / Copilot | Search "memex" in VS Code Extensions — install and done, no extra setup |
| Claude Code | /plugin marketplace add iamtouchskyer/memex then /plugin install memex@memex |
| Cursor | First npm install -g @touchskyer/memex, then one-click install |
| Codex | npm install -g @touchskyer/memex && codex mcp add memex -- memex mcp |
| Pi | npm install -g @touchskyer/memex && pi install npm:@touchskyer/memex |
| Windsurf / others | npm install -g @touchskyer/memex, then add MCP server: command memex, args ["mcp"] |
That's it — no extra setup needed. The MCP tool descriptions tell your agent when to recall and retro.
Upgrade
| Platform | How |
|----------|-----|
| VS Code / Copilot | Extension auto-updates from marketplace |
| Claude Code | /plugin uninstall memex then /plugin install memex@memex |
| Pi | npm update -g @touchskyer/memex and re-copy pi-extension/index.ts |
| Cursor / Codex / Windsurf | npm update -g @touchskyer/memex |
Cross-platform sharing
All clients read and write the same ~/.memex/cards/ directory. Sync across devices with git:
Prerequisite: Auto-create requires GitHub CLI (
gh auth login). Or pass your own git remote URL to skip this, including GitLab and self-hosted GitLab remotes.
memex sync --init # auto-creates private memex-cards repo on GitHub
memex sync --init <repo-url> # or specify your own repo URL (no gh/glab CLI needed)
memex sync on # enable auto-sync after every write
memex sync # manual sync
memex sync off # disable auto-sync
For GitLab, create an empty private repository first, then pass its SSH or HTTPS remote URL. See the GitLab sync guide for examples.
Browse your memory
memex serve
Opens a visual timeline of all your cards at localhost:3939. Includes a graph view to explore bidirectional links.
If you've set up sync, memex serve opens memra.vercel.app — a web UI with Timeline, Graph view, and Share card. Pass --local to force the local UI instead (useful offline, or when you'd rather not send queries to a third-party web app):
memex serve --local
CLI reference
memex search [query] # search cards, or list all
memex read <slug> # read a card
memex write <slug> # write a card (stdin)
memex links [slug] # link graph stats
memex archive <slug> # archive a card
memex serve # visual timeline UI
memex sync # sync via git
memex mcp # start MCP server (stdio)
How it works
Based on Niklas Luhmann's Zettelkasten method — the system behind 70 books from 90,000 handwritten cards:
- Atomic notes — one idea per card
- Own words — forces understanding (the Feynman method)
- Links in context — "this relates to [[X]] because..." not just tags
- Keyword index — curated entry points to the card network
Cards are stored as markdown in ~/.memex/cards/. Open them in Obsidian, edit with vim, grep from terminal. Your memory is never locked in.
Privacy guardrails
Do not put actual secrets, credentials, tokens, or exact secret file contents into memex queries or cards. Use abstract descriptions and redacted examples instead.
Memex rejects high-confidence raw secrets, redacts credentials embedded in URLs before saving, and masks webhook/tokenized URLs in display output. It cannot hide unsafe tool-call arguments that your AI client has already shown in its transcript, so redact before calling tools.
Configuration
Optional settings go in ~/.memex/.memexrc (JSON):
{
"nestedSlugs": true,
"searchDirs": ["shared"],
"experimental": {
"agenticMemory": true
}
}
| Key | Type | Default | Description |
|-----|------|---------|-------------|
| nestedSlugs | boolean | false | Allow / in slugs for hierarchical card paths |
| searchDirs | string[] | — | Extra directories to search with --all (in addition to the built-in cards/ store) |
| experimental.agenticMemory | boolean | false | Enable A-MEM-inspired agentic memory workflow (see below) |
Experimental: Agentic Memory
When experimental.agenticMemory is true, agents gain access to a structured memory skill that guides them through: observe → draft atomic card → enrich metadata → retrieve candidates → decide (create/update/skip) → preview → write → verify.
This produces higher-quality cards with agent-proposed [[wikilinks]] (links are suggested after candidate retrieval and agent review, never added from keyword or embedding similarity alone) and metadata enrichment, compared to the default recall/retro workflow. The feature is default-off and does not change any existing behavior when disabled.
See skills/memex-agentic-memory/SKILL.md for the full skill specification and docs/ARCHITECTURE.md for config details.

AI 编程 agent 的持久记忆系统。让你的 agent 跨会话记住学到的知识。
每次 agent 完成任务后，它会将洞察保存为带有 [[双向链接]] 的原子知识卡片。下次会话时，agent 会先回顾相关卡片再开始工作——基于已有知识继续，而非从零开始。
无需向量数据库，无需 embedding——只是你和 agent 都能读取的 markdown 文件。

AIコーディングエージェントのための永続メモリシステム。エージェントがセッションをまたいで学んだことを記憶します。
エージェントがタスクを完了するたびに、[[双方向リンク]]付きのアトミックな知識カードとしてインサイトを保存します。次のセッションでは、作業開始前に関連カードを呼び出し、ゼロからではなく既存の知識の上に構築します。
ベクトルデータベースもembeddingも不要——エージェント（とあなた）が読めるmarkdownファイルだけです。
