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.

<table> <tr> <td width="25%" valign="top">

Independent Workspace

No dependency on a specific IDE or terminal.

Projects, sessions, reviews, previews, and agents all live in their own workspace.

</td> <td width="25%" valign="top">

Plugin-Powered

Plugins extend more than the agent.

Add panels, views, widgets, tools, MCP servers, themes, and background services.

</td> <td width="25%" valign="top">

Agent Orchestration

One agent is not always enough.

Delegate to Subagents or coordinate full Worker Sessions in parallel.

</td> <td width="25%" valign="top">

Model Freedom

Cloud models, local models, custom gateways, compatible APIs.

Switch models without rebuilding your workflow.

</td> </tr> </table> <div align="center">

It is not a wrapper around one model. It is not another IDE extension.

It is a desktop platform for agent workflows.

</div>

---

Plugins are part of the workspace, not an afterthought

PI-Desktop keeps the Core focused.

Your actual workflow is assembled through extensions.

<table> <tr> <td width="33%" valign="top">

Agent

Extend what the agent can do

Agent Tools Skills Completion pi Extensions

</td> <td width="33%" valign="top">

Workspace

Extend the desktop itself

Commands Panels Work Panel Views Floating Widgets Themes

</td> <td width="33%" valign="top">

Platform

Extend the runtime

MCP Servers Resident Services Plugin Message Bus

</td> </tr> </table>

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.

                       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

<table> <tr> <td width="33%" valign="top">

Agent

Give it a task. Let it work.

Read code, edit files, run commands, test, and iterate.

Best for day-to-day development.

</td> <td width="33%" valign="top">

Plan

Review the approach before execution.

The agent studies the project first and produces an implementation plan.

Best for refactors and high-risk changes.

</td> <td width="33%" valign="top">

Goal

Define the outcome. Let the agent choose the path.

Lock the objective and acceptance criteria, then let the agent drive execution.

Best for complex and long-running tasks.

</td> </tr> </table>

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

<table> <tr> <td width="50%"> <img src="docs/image/readme/session-orchestrator-overview.png" alt="Session Orchestrator" /> <p align="center">_{Coordinate multiple Worker Sessions from one parent Session}</p> </td> <td width="50%"> <img src="docs/image/readme/session-orchestrator-worker.png" alt="Worker Session" /> <p align="center">_{Each Worker remains a full, inspectable Session}</p> </td> </tr> </table> <div align="center">

Move from “one agent helps me code” to “multiple agents divide and complete the work.”

</div>

---

Built for work that lasts

PI-Desktop is organized around:

<div align="center">

Project → Session → Agent → Work

</div>

—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

A Session can continue across multiple app launches.

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.

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.
