PI-Desktop

A modular desktop workspace for AI agents

Bring projects, agents, models, plugins, and workflows into one persistent desktop environment.

Local-first · Model-agnostic · Plugin-powered · macOS / Windows / Linux

Download · Documentation · Build a Plugin · Screenshots · 简体中文

Your projects stay local · Your models stay replaceable · Your workspace stays yours

---

Why PI-Desktop?

Terminal agents are great at execution. IDE agents are great at living inside an editor.

PI-Desktop goes one step further:

Give AI agents a persistent, independent, and extensible desktop workspace of their own.

---

Plugins are part of the workspace, not an afterthought

PI-Desktop keeps the Core focused.

Your actual workflow is assembled through extensions.

A plugin does not have to be “just another tool.”

It can be an entire product:

Voice Agent
├── Floating Widget
├── Speech Service
├── Agent Tool
└── Commands
GitHub Workspace
├── Work Panel
├── MCP Server
├── Agent Tools
└── Background Service
Session Analytics
├── Dashboard
├── Commands
└── Workspace View

What can a plugin add?

| Capability | What it enables | | ------------------- | -------------------------------------------------------------- | | Command | Add actions to the global command system | | Panel | Open a standalone plugin interface | | Floating Widget | Build voice orbs, status lights, timers, and other floating UI | | Work Panel View | Add new views to the right-side workspace | | Agent Tool | Register tools callable by the agent | | Completion | Use the models already configured by the user | | Skill | Add reusable agent capabilities and workflows | | Theme | Customize workspace appearance | | MCP Server | Connect local or remote MCP servers | | Service | Run persistent background work | | Message Bus | Let plugins communicate with each other |

Plugins can be distributed as .piplug packages or installed through the marketplace.

One foundation, many workflows

                       Your Workflow

PI-Desktop can simply be your coding agent.

Or you can turn it into:

AI Development Workspace · Voice Agent · DevOps Console · GitHub Workspace · Data Assistant · Multi-Agent Control Center · Automation Platform

The Core provides the foundation. Plugins decide what your workspace becomes.

---

Three ways to work

Privileged operations still pass through PI-Desktop's permission layer.

---

When one agent is not enough

Complex work should not be forced into one context window.

PI-Desktop provides two levels of delegation.

Subagents

Delegate independent work to background agents:

Code exploration · Implementation · Test analysis · Research · Review

Each Subagent gets its own context and reports the result back to the parent agent.

Session Orchestrator

For longer-lived work, delegate to full Worker Sessions.

Main Session
│
├── Worker A
│   └── Frontend
│
├── Worker B
│   └── Backend
│
├── Worker C
│   └── Tests
│
└── Worker D
    └── Review

Workers are full PI-Desktop sessions:

Independent context · Independent execution · Directly inspectable · Reusable · Full transcript

Coordinate multiple Worker Sessions from one parent Session

Each Worker remains a full, inspectable Session

---

Built for work that lasts

PI-Desktop is organized around:

—not around disposable chat threads.

You can:

• Manage multiple projects and sessions
• Pin, archive, branch, and search sessions
• Queue prompts while an agent is already running
• Reference project files with @
• Use slash commands
• Review diffs
• Inspect command output
• Work with the right-side Work Panel
• Keep streaming checkpoints
• Recover interrupted work whenever possible

---

See what the agent is doing

Persistent Sessions instead of disposable chats	Switch models and reasoning levels inside the Session
A plugin marketplace that extends both the agent and the desktop	Connect your own provider, gateway, or local model

---

Swap the model, keep the workflow

PI-Desktop does not tie your workflow to a single model vendor.

Use:

OpenAI · Anthropic · OpenAI-Compatible APIs · Custom Gateways · Ollama · LM Studio · Local Models

Configure each model independently:

Provider · Model ID · Context Window · Output Limit · Reasoning / Thinking · Temperature · OAuth · API Key · Endpoint

Different Sessions can use different models.

The same Session can switch models at any time.

Planning     → Model A
Coding       → Model B
Review       → Model C
Private Task → Local Model

The model is a replaceable component of the workflow — not the workflow itself.

---

Already using another coding agent?

Keep your existing work.

PI-Desktop can import local sessions from:

Claude Code · Codex · OpenCode · Pi

---

Local-first

PI-Desktop does not require you to move your development environment into our cloud.

| Data | Default behavior | | -------------------- | ----------------------------------------- | | Projects | Local | | Sessions | Local | | Settings | Local | | Logs | Local | | API credentials | OS Keychain | | PI-Desktop telemetry | None | | Model requests | Sent directly to your configured provider |

No mandatory PI-Desktop account.

No mandatory PI-Desktop relay.

When using a remote model, the context required for the request is sent directly to that provider.

---

You control the permissions

Agents can read files, edit code, run commands, call tools, use extensions, and delegate work.

Privileged operations still pass through the permission layer:

Agent
  ↓
Tool Request
  ↓
Permission Layer
  ↓
Allow / Ask / Deny
  ↓
Execution

You decide how much autonomy each Session gets.

Built on Pi

PI-Desktop is built on the pi ecosystem.

The Agent Runtime uses:

• pi-ai
• pi-agent-core

Pi provides the Agent Engine. PI-Desktop builds the persistent desktop workspace, sessions, permissions, plugins, and agent orchestration around it.

---

For Developers

PI-Desktop can also serve as a host platform for building agent products.

You can build:

Plugins · MCP Servers · Skills · Agent Tools · pi Extensions · Themes · Panels · Floating Widgets · Background Services

Plugin quick start

Built-in templates include:

• panel-basic
• agent-tool-basic
• skill-pack
• full-demo

Model Acknowledgements

Not by a lone genius, but by a token-powered construction crew.

PI-Desktop has been built with the help of models from multiple providers.

More than 27 billion tokens have been used across development, refactoring, review, design, and debugging.

Thanks to every human contributor — and every model that helped us build it.
