Context for your AI

Stop pasting context manually. Use the MCP Server to let Claude/Cursor read your snippets directly.

User: @CodeMenu fetch the 'stripe-webhook' snippet AI: Found it. Generating test cases based on your saved webhook handler...

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 2025 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

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"

AI

MCP Server

Connect CodeMenu to Claude Desktop or Cursor. Give your AI agent read-access to your personal documentation and verified code patterns.

Engineered for Focus

Structured for Focus

Context switching kills flow. Use Spaces to isolate only the snippets relevant to your current project. Dump temporary ideas into Stashes for quick access without the clutter. Of course, standard Groups and Tags are there when you need them.

Visual Knowledge Graph

Knowledge doesn't live in isolation. Link an OSINT screenshot to your research notes, or a database config to its migration script. Navigate your knowledge base visually to rediscover connections you forgot you made.

First-Class Artifacts

It's 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.

Various content types including images and code

Run & Preview

Don't just store code—execute it. Run shell scripts directly from the app, preview HTML/JS snippets in a sandboxed web view, or test that Regex before you commit it.

Headless & Scriptable

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

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

Complete Developer Toolkit

A Swiss Army knife for your daily tasks. Includes a code image generator, JSON formatter, UUID generator, and more. Everything you usually Google for, now offline and instant.

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.

Locally on your Mac in a standard SQLite database. 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.
