Introduction

ContextPin is a desktop app that helps you manage, organize, and instantly share context with AI coding assistants.

ContextPin is a powerful desktop application designed to solve one of the biggest challenges in AI-assisted coding: context management. Instead of repeatedly explaining your project's architecture, coding standards, and requirements to AI tools, ContextPin lets you create, organize, and instantly share this context across all your AI conversations.

What is ContextPin?

Think of ContextPin as a knowledge base that your AI assistants can access anytime. You create "contexts" — documents containing project guidelines, API documentation, code standards, architecture decisions, and more — and these contexts are automatically available to any AI tool that supports the Model Context Protocol (MCP).

Model Context Protocol (MCP) is an open standard that allows AI applications to securely access external data sources. ContextPin uses MCP to make your contexts available to tools like Claude Desktop, Claude Code, Cursor, and more.

Key Features

  • Hierarchical Organization — Organize contexts in folders and subfolders, just like files on your computer
  • Rich Text Editor — Format your contexts with headings, code blocks, lists, and more
  • Cross-References — Link contexts together to create a connected knowledge base
  • File References — Reference specific files from your repositories
  • MCP Integration — Works with any AI tool that supports the Model Context Protocol
  • Local-First — Your data stays on your machine, giving you full control

Use Cases

Project Documentation

Store your project's architecture decisions, API guidelines, coding standards, and technical specs. When working with an AI assistant, it can access these documents to provide more accurate, context-aware responses.

Team Onboarding

Create a comprehensive knowledge base that helps new team members (and AI assistants) understand your codebase, conventions, and best practices.

AI Consistency

Ensure consistent AI responses across conversations by always providing the same foundational context. No more re-explaining your coding style or project structure.

Quick Start

  1. Download ContextPin for your platform
  2. Install the application
  3. Create your first context in the app
  4. Set up MCP integration with your favorite AI tool
