## TL;DR: Plugged.in

<Warning>
  **The future of AI won't be about bigger models—it'll be about smarter connections.**
</Warning>

Plugged.in is the unified control plane that solves a critical problem in today's AI landscape: **fragmentation**. Every AI platform—Claude, ChatGPT, Cursor, LM Studio—keeps its own isolated ecosystem of tools, documents, and context. This means you're constantly re-uploading documents, reconfiguring tools, and losing continuity as you switch between models.

Plugged.in changes this by creating **one governed layer** where your knowledge, tools, and memory stay with you across every AI model and platform.

## The Three Pillars

<CardGroup cols={3}>
  <Card title="📚 Knowledge Base" icon="book-open">
    **✅ IN PRODUCTION**<br />
    Your documents become a living, searchable knowledge base accessible to any AI. Upload once, and every model can query your PDFs, docs, and files through RAG-powered semantic search. AI models can even create and collaborate on documents directly in your library, with complete version history and model attribution—so you always know which AI (Claude, ChatGPT, etc.) contributed what.<br />
    <em>Think of it as GitHub for AI-generated content: full version control, complete ownership, and cross-platform availability.</em>
  </Card>

  <Card title="🔧 Tools" icon="wrench">
    **✅ IN PRODUCTION**<br />
    The Model Context Protocol (MCP) standardized how AI clients connect to external tools, but managing MCP servers is still fragmented—configure once in Claude Desktop, then again in Cursor, then again in VSCode. Plugged.in's universal MCP proxy eliminates this pain: install once, access everywhere.<br />
    With 1,500+ MCP servers in the registry and automatic OAuth token management, you get one-click tool installation that works across Claude Desktop, ChatGPT, Cursor, Cline, VSCode, LM Studio, and any MCP-compatible client. Configure your tools once, use them everywhere.
  </Card>

  <Card title="🧠 Memory" icon="brain">
    **✅ IN PRODUCTION (v2.20.0)**<br />
    Persistent clipboard storage for AI workflows. Store named key-value pairs or use stack-based indexed storage. Features TTL expiration, multiple content types (text, JSON, base64), and cross-platform access via MCP tools and SDKs. Profile-isolated and secure.<br />
    <em>Coming soon: Focus Agent, Short-term & Long-term Memory tiers.</em>

## What is Plugged.in?

**Plugged.in is the crossroads for AI data exchanges** - the unified control plane that brings your **Knowledge • Tools • Memory** to every AI model. Install once, govern everywhere.

<Info>
  **The Problem:** Every AI model keeps its own tools, documents, and memories → fragmentation & cost.<br />
  **The Solution:** One governed layer for Memory · Knowledge · Tools across every model.
</Info>

<Info>
  **For beginners:** MCP (Model Context Protocol) servers are like apps that give AI models access to external tools and data. Instead of each AI platform having its own tools, MCP creates a standard way for AI to use the same tools everywhere.
