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.
Independent Workspace
No dependency on a specific IDE or terminal.
Projects, sessions, reviews, previews, and agents all live in their own workspace.
Plugin-Powered
Plugins extend more than the agent.
Add panels, views, widgets, tools, MCP servers, themes, and background services.
Agent Orchestration
One agent is not always enough.
Delegate to Subagents or coordinate full Worker Sessions in parallel.
Model Freedom
Cloud models, local models, custom gateways, compatible APIs.
Switch models without rebuilding your workflow.
It is not a wrapper around one model. It is not another IDE extension.
It is a desktop platform for agent workflows.
Plugins are part of the workspace, not an afterthought
PI-Desktop keeps the Core focused.
Your actual workflow is assembled through extensions.
Agent
Extend what the agent can do
Agent Tools Skills Completion pi Extensions
Workspace
Extend the desktop itself

Platform

MCP Servers Resident Services Plugin Message Bus
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
