How Intelligent Terminal Adds an AI Sidebar to Windows Terminal

It’s Not a New Terminal, It Adds an AI Panel to Windows Terminal

Many might think this is “another AI terminal”, but Intelligent Terminal is a fork of Windows Terminal that retains all its features—tabs, split panes, themes, configuration, shortcuts—and adds an Agent panel on the right, left, or bottom. The panel connects to an AI tool via the Agent Client Protocol (ACP).

ACP‑compatible tools include GitHub Copilot CLI (default), Claude Code, Codex, Gemini CLI, or a custom local agent. On first launch it automatically detects which agents are installed and can install Copilot if missing.

Three Design Choices That Save Developers Time

Error auto‑detection → auto‑send to Agent When a command fails, a small icon appears in the status bar. Press Ctrl+Alt+. to pop up the Agent panel with the error context already filled, so you can send it to the AI with a single Enter.

Agent follows the focused pane In multi‑pane setups (e.g., vim, logs, ssh), the Agent tracks which pane has focus and automatically switches context when you change panes, avoiding mismatched output.

Background tasks don’t block the foreground pane If the Agent needs more time (e.g., refactoring, searching docs, writing tests), it opens a new tab to run the task in the background, keeping the main shell responsive.

It’s Not the Same as Grok Build or Claude Code

Intelligent Terminal is not another coding agent; it is a panel that invokes existing agents.

Claude Code / Codex / Grok Build : agents that can think, call tools, and execute commands.

Windows Terminal : the standard terminal emulator on Windows.

Intelligent Terminal : a Windows Terminal fork that embeds the three agents in a side panel.

The goal is to lower the barrier to using agents—previously you had to switch between the terminal and an AI tool; now the AI lives beside the terminal.

What It’s Like in Practice

The README lists several useful shortcuts: Ctrl+Shift+. — toggle the Agent panel Ctrl+Alt+. — invoke the Agent when an error appears Ctrl+Shift+/ — manage Agent sessions Alt+Shift+B — open a clean Agent tab

The logic behind these shortcuts is: the panel stays resident, errors get priority, and tasks run without blocking. It’s aimed at daily developers, not just geeks.

Data Flow and Privacy Considerations

Intelligent Terminal itself does not connect to the internet; it merely forwards your prompts and shell output via ACP to the selected Agent CLI.

Where the data goes depends on the chosen agent:

GitHub Copilot → GitHub backend (enterprise edition offers a zero‑retention policy)

Claude Code → Anthropic backend

Custom Agent → your own backend

This transparency makes it clear that swapping agents changes the data destination while keeping the user experience consistent.

Who Should Install It

Developers who work exclusively on Windows (the fork only runs on Windows 10 2004+).

Existing Windows Terminal users, especially .NET, PowerShell, or WSL developers, who can add the AI panel in minutes without altering their workflow.

Teams that want AI assistance for error fixing, script refactoring, or test generation but are hesitant to adopt full‑stack AI terminals; Intelligent Terminal offers “AI as a helper, not the main actor.”

Who It’s Not For

Mac/Linux users (the project explicitly targets Windows).

Anyone seeking a brand‑new AI‑first terminal; they should look at Grok Build or Claude Code.

Those expecting an out‑of‑the‑box, feature‑complete product—Intelligent Terminal is still at v0.1.x and evolving rapidly.

Final Thoughts

The biggest shift in coding agents over the past two years is moving from “launch‑and‑run” to “always‑on.” Copilot‑style agents are invoked manually, whereas Intelligent Terminal keeps an agent resident, ready to act as soon as an error appears.

This “passive response” design may point to the future of IDEs and terminals. Microsoft’s decision to fork Windows Terminal signals its endorsement of this direction: AI is not meant to replace the terminal, but to live alongside it.
