Run many Claude Code sessions.
Never lose track.

A macOS workbench around the real Claude Code CLI. Live states for every session, one key to the next one waiting for you, every change traced to the session that made it.

The real claude CLINot a wrapper. Your Claude Code, its status line, its commands.
Sessions that stay aliveQuit, update, restart: your sessions keep going.
Keyboard firstEvery action a shortcut away. ⌘K finds the rest.

Sessions

Know who needs you.

Every session shows what it is doing. When one needs you, you know — and ⌘J takes you there.

Needs permission, has a question, working, done, failed
Notification center, Dock menu and banners
Background agents and shells, context, limits and cost

Sessions grouped by state: two need you, two are working, one is done

Workspace

Everything side by side.

Sessions, terminals and files are tabs. Put up to three side by side and keep your hands on the keyboard.

Split view with up to three panes (⌘\)
Command palette (⌘K) for files, sessions and commands
Context menus everywhere

Changes

See who changed what.

Every changed file carries the colour of the session that touched it — down to the exact command.

Changes by session or by repository
Review with line comments sent back to Claude
Source Control history graph, pull request and CI chips

The diff of a file Claude changed, next to the changed files coloured by session

Editor

A real editor next to Claude.

Open, edit and save files without leaving the session. When Claude edits the same file, nothing gets lost.

Fast editor with find, comments and syntax colours
Compare, keep yours or reload when Claude changes a file
⌘L mentions the selected lines in the session

A TypeScript file with its changes marked in the margin, next to the session that made them

Dictation

Talk to Claude.

Hold ⌥Space and speak. Transcription runs on your Mac, so your voice never leaves it.

On-device transcription with whisper.cpp on Metal
Optional clean-up of the text by Claude Haiku (the text, never the audio)
Off until you turn it on

The dictation pill listening while Claude waits for an answer

Always alive

Close the app. Your sessions keep going.

A background service owns your terminals. Quit Atelier, install an update or restart your Mac: pick up where you left off.

Sessions keep running when the window closes
Updates install on restart without closing sessions
Resume past conversations from the sidebar (⌘⇧N)

Atelier reopened with the same sessions still running
