AI-Powered

Chat with your snippets using the built-in AI, or connect external agents via the MCP Server. Your knowledge base becomes the context layer for every AI tool you use.

You: How do I use the CVE calculator? AI: Based on your "CVSS v3.1 Base-Score Calculator" snippet…

Scriptable Actions

Automate your knowledge base maintenance. Write scripts to bulk-refactor code, validate snippet syntax, or generate reports. Full access to read and modify your library programmatically.

            // Example: Add license header to all Swift
                files
            const license = "//
                Copyright 2026 Extiri\n";
            
            for (let i = 0;
              i < snippets.length; i++) {
                 let s = snippets[i];
                 if (s.lang === "swift" && !s.code.includes("Copyright")) {
                 s.code = license + s.code;
                 s.update(); //
                    Persist changes
                 alert("Updated", s.title);
                 }
                }

Integration

The missing layer in your stack

CodeMenu sits between your editor, your terminal, and your AI tools.

Side Window

Side Window & Suggestions app

Keep CodeMenu pinned next to VS Code or Xcode. Drag and drop snippets, or use the Suggestions companion app to find relevant code without leaving your editor (type §§).

Suggestions App

CLI

Terminal Access

Access your library via cdmn. Features a TUI for browsing, fuzzy search for quick retrieval, and scriptable output (like JSON).

            # Install cdmn
            $ go install github.com/extiri/cdmn@latest
            
            # Fuzzy search for "show alert"
            $ cdmn get "show alert"
          

CodeMenu CLI

AI

MCP Server

Connect CodeMenu to Claude Code, OpenAI Codex, VS Code and any other app with support for MCP. Give your AI agent read-access to your personal documentation and verified code patterns.

MCP Server

Engineered for Focus

Keep the working context visible, searchable, and ready to reuse

CodeMenu is built around the pieces that make developer work repeatable: focused spaces, connected artifacts, quick previews, and automation hooks that keep your library close to the tools you already use.

Structured for Focus

Context switching kills flow. Use Spaces to isolate only the snippets relevant to your current project. Drop temporary ideas into Stashes for quick access without the clutter, while Groups and Tags remain available when a broader taxonomy helps.

Visual Knowledge Graph

Knowledge does not live in isolation. Link an OSINT screenshot to research notes, or connect a database config to its migration script. Navigate your library visually and rediscover connections you already made.

First-Class Artifacts

It is not just a text bucket. CodeMenu renders Markdown with LaTeX support, previews images and colors, and highlights syntax for 60+ languages. Store the entire context of your work, from PDFs to shell scripts.

Run & Preview

Do not just store code. Execute shell scripts directly from the app, preview HTML and JavaScript in a sandboxed web view, and test a regular expression before you commit it.

Various content types including images and code

Headless & Scriptable

The built-in HTTP server exposes your library to local tools. Fetch snippets with curl, integrate with Raycast, or write JavaScript automations that transform content on paste.

# Access your snippets from anywhere $ curl localhost:1300/v1/snippets

Built-in AI Chat

Ask about snippets, patterns, APIs, or concepts inside CodeMenu. AI retrieves relevant snippets from your own library, so answers are grounded in your code instead of generic examples.

Shortcuts Integration

CodeMenu ships with Shortcuts actions to create, search, update, and organise snippets, groups, and tags without opening the app.

And So Much More

Generate shareable code images, recognise text from screenshots, encrypt sensitive snippets, sync via iCloud, publish to GitHub Gists, or host your own Snippets Store.

More than a snippet manager

	Basic snippet tools	CodeMenu
Content types	Text	Code, prompts, images, colors, notes
Organization	Folders, tags	Folders, tags, graph links
Search	Text search	Text search + semantic search
Automation	Text expansion	JavaScript, HTTP calls, dynamic placeholders
Data storage	Cloud	Local (offline-first)

FAQ

It's a developer knowledge base. While it excels at snippets, it's designed to store your entire context: API responses, design tokens, prompt templates, and research notes. It's the long-term memory for your shipping workflow.

Yes, it does. You can sync your snippets and some settings across your devices using iCloud by enabling it in the settings.

CodeMenu supports two types of models for the AI chat and generation features. First is builtin which allows you to use Mistral 7B and Gemma 2 2B. Second is Ollama app. If you download Ollama you can then connect CodeMenu to it and use any model available through it.

CodeMenu is offline-first and privacy-focused. Your code never leaves your machine unless you explicitly choose to share it.

The built-in HTTP server provides a local API for your other tools to access your library. It is not for public sharing. Use it to fetch snippets via scripts, integrate with Raycast/Alfred, or build custom workflows that need access to your knowledge base.

Yes. CodeMenu is designed to be the context layer for your AI. Use the MCP server to let Claude or other agents query your library, or use the local semantic search to find relevant context to paste into your LLM.

Yes, there is a 7-day free trial available on the Mac App Store. You can choose between a one-time purchase or a subscription.
