We’re thrilled to unveil the public preview of AI Shell! AI Shell enhances your shell with AI capabilities to facilitate your interactions with the command line. AI Shell create an interactive shell that can interact with various large language model and provides a framework that you can use to build a custom system that meet your needs. Users can interact with the AI agents in a conversational manner.

The AI Shell project includes:

• The command-line shell (aish) interface
• A framework for creating AI agents and other assistance providers
• A PowerShell module for deeper integration with PowerShell.
• Built in AI agents to get you started assistance immediately

Each AI assistant is known as an agent. The initial release of AI Shell includes two agents:

1. Azure OpenAI Agent: Powering general-purpose assistance, the Azure OpenAI agent can use any of the AI models provided by Azure open AI to handle broad queries, natural language interpretations or code generation. You can connect it to your deployed Azure OpenAI models if you are looking for more privacy, management of the model settings, or have a model trained with your data. Additionally, you can also utilize OpenAI’s models.
2. Copilot in Azure: This agent brings the power of Copilot in Azure directly to your CLI. It specializes in delivering cloud-centric assistance, providing Azure CLI and Azure PowerShell commands and helping you automate your Azure-specific tasks.To get started with the Copilot in Azure agent you need sign in to Azure with Azure CLI with an account that has the IAM role for accessing Copilot in Azure.

Recognizing that you may have different CLI command needs, AI Shell provides a framework for creating your own agents. For more information, see Creating an Agent.

Using and Installing AI Shell

We know every CLI user has their own preferences, so AI Shell offers two flexible modes to fit your workflow:

Standalone Executable

You can use AI Shell as a self-contained executable, allowing it to run independently from any shell. This setup is perfect if you’re looking for a dedicated, streamlined experience that’s easily accessible without dependencies.

Side-by-Side Integration with PowerShell 7

This is the recommended method for using AI Shell because it enables an uninterrupted work flow. The AIShell module connects the aish tool to your PowerShell 7 session for deeply integrated user experience. AI Shell opens in a side pane right next to your PowerShell 7 session that enables a rich communication between panes, results from the chat can be carried seamlessly to your PowerShell session for easy execution and the AI agent can be used to provide assistance to resolve a PowerShell error.

Installation and Getting Started

Some system requirements are needed to run AI Shell.

AI Shell (aish) and the AIShell module are separate downloads. For your convenience, we created a script to download and install them for you.

Windows

Some prerequisites are needed to run AI Shell on Windows.

• Windows 10 or higher
• PowerShell 7.4.6 or higher
• Windows Terminal

The following install script will:

• Installs aish.exe to $env:LOCALAPPDATA\Programs\AIShell and adds it to your PATH
• Installs the AIShell module to your module path location

MacOS

Some prerequisites are needed to run AI Shell on MacOS.

• macOS v13 Ventura or higher
• PowerShell 7.4.6 or higher
• iTerm2 terminal app

On MacOS, this script:

• Installs the aish executable to /usr/local/AIShell and creates a symbolic link at /usr/local/bin/aish
• Due to some limitations, the AIShell module is not installed

To install AI Shell, run the following command in your PowerShell session:

Invoke-Expression "& { $(Invoke-RestMethod 'https://aka.ms/install-aishell.ps1') }"

To find details on manual installation please see, Installing AI Shell manually.

After running the install script, you can run Start-AIShell to begin using AI Shell.

AI Shell starts in the side by side experience. You can switch between the agents by using the @<agent name> command. For example, to switch to the Azure OpenAI agent you would use the @openai-gpt command. Additionally you can do @<agent name> <question> to send a question to the agent immediately.

Inserting code into the PowerShell 7 session

Copying and pasting a lot of code can be annoying. AI Shell makes it easy to insert the AI generated code directly into your PowerShell 7 session with the /code post command. In your AI Shell, run /code post or use the Ctrl+d,Ctrl+d keyboard shortcut to copy the code into your PowerShell session.

If you are familiar with PowerShell 7 you may be familiar with Predictive Intellisense. When you get multi-step commands in your AI Shell response, you can easily get each subsequent step in your Predictive Intellisense buffer.

Resolving errors quicker

If you encounter an error in your working terminal, you can use the Resolve-Error cmdlet to send that error to the open AI Shell window for resolution. This command asks the AI model to help you resolve the error.

Invoking AIShell from PowerShell 7

One key scenario we wanted to support is being able to pipe output of one command into the AI Shell to get more information or ask a follow up question on the data given. With the Invoke-AIShell command you can easily do this.

Invoke-AIShell can take input from the pipeline but also can just be used to call the AI agent selected in AI Shell without having to switch back and forth.

Some additional tips using AI Shell

There are other chat commands and hot-keys that make using AI Shell easier. For a full list of the chat commands, see the AI Shell reference.

Additionally, you can switch between the panes easier using the following keyboard shortcuts.

Why Try AI Shell?

AI Shell was built for those who seek intelligence and adaptability from their command-line. With multi-agent support, AI Shell aims to be the assistant for any CLI tool. You’ll benefit from advanced AI capabilities, deeper integration with your PowerShell session, and an extensibility model to get the assistance you need.
