Code IDEA real IDE, with your coding agent living in it.

Point Circuitry at a folder on your Mac, PC or Linux box and it becomes an IDE around it — the real files, the file tree, source control, terminals — with Claude Code, Gemini CLI or Codex CLI running in the pane beside the code they are editing.

Part of Circuitry Studio — the same AI works in every surface, on the models you choose.

Open the folder. It is your project.

  • The left panel becomes the project tree — the actual directory on disk, with the files you already have open marked.
  • Every file opens as a tab in the editor that suits it: code, markdown, HTML, images, PDFs, data files.
  • A source-control panel tracks the working tree — changes, staging, commits, branches.
  • Terminals open in the same window, on the same machine as the files.
The Circuitry code IDE: project file tree on the left, a TypeScript file open in the centre, and Claude Code running in the agent pane on the right

One window: the project, the file, and the agent working on it.

Claude Code, Gemini CLI and Codex CLI run in the pane beside your code.

Pick one from the chat’s menu and it runs on the machine holding the project — your repositories, your toolchain, the CLI you already installed. The same menu holds hosted Claude, GPT and Gemini models, a local model on your own hardware, and Apple Intelligence in the app on recent Apple hardware. You can change model part-way through a conversation.

Hosted models, on-device models, and the command-line assistants, in one menu.

Code edits arrive as accept-or-reject hunks.

  • Each change lands in the editor as a hunk with its own Accept and Reject.
  • A review bar counts what is still pending, with Accept All and Reject All.
  • An inline edit you asked for over a selection is staged the same way.
  • A command-line assistant editing a file you have open lands there too, instead of overwriting it underneath you.
Agent edits arrive as hunks — Accept or Reject each, with the bar counting what is still pending.

Live split preview

The preview is built from the buffers you have open and the project’s own modules, so it moves as you type. Hover a line and the element lights up in the render; hover the render and the code selects, then click to land on that exact element. Markdown and HTML files open the same way.

A React component, and the page it renders, in one tab.

Language servers, running on your machine.

  • TypeScript is checked as a project: it reads your tsconfig, loads your sources, and resolves imports across files.
  • Pyright, gopls, rust-analyzer and clangd install on request from the editor’s status bar — Python, Go, Rust, C and C++.
  • Hover types, completions, signature help and go-to-definition come from the server, not from a heuristic.
  • A chip in the status bar names the one that is running, and offers the one that isn’t.

A language server indexes a directory, so it needs a project folder open on a machine you have connected.

Vim keys, multiple cursors, and the transform no menu has.

  • Vim keybindings in every code editor, toggled with Cmd+Shift+V (Ctrl+Shift+V on Windows and Linux) once you have turned them on.
  • Multiple cursors: the next occurrence, every occurrence, or one cursor per selected line.
  • Rename Symbol understands scope, so it leaves the same-named variable in another function alone.
  • Filter Through Command sends the selection to a Python or shell command and replaces it with the output — and will write that command from a plain description of what you want.

The same editor runs inside workflow steps and notebook cells.

The same editor that holds your project files holds the code on a workflow step and in a notebook cell, where a step can be JavaScript, TypeScript, Python, Three.js, Shell, Go, Rust, C, C++ or Zig. The same agent reads your whiteboards, designs, workflows and terminals too — so you can point at a diagram and ask for the code that implements it.

Point it at your project and start.
