AI Coding Workspace
A native desktop surface for real coding tasks. Plan, inspect, run, and review with an agent that respects your project context.
macOS · early build
Code in flow.
Let the room tune itself.
CodeNocturne is a macOS coding workspace that pairs an AI coding agent with an adaptive music agent — so you stay focused, calm, and immersed in the work.
Available for macOS · Apple silicon & Intel · macOS 13+
Built for the parts of coding that aren’t about typing.
Three quiet capabilities, designed to keep one long thread of work in view.
Music-aware Focus
Soundscapes shaped around the work in front of you. Not a player tacked on — ambience tuned for long passes of attention.
Local Desktop Flow
Native macOS. Quiet by default. Designed to live alongside your editor without taking the room.
Sessions designed around how you actually code.
Four small steps. No theatre. Just the conditions for deep work.
- 01
Start a session
Tell CodeNocturne what you’re working on — a feature, a fix, a refactor.
- 02
Let the agent read the room
It scans the task and the surrounding context before doing anything.
- 03
Music settles in
The Music Agent picks an ambience that fits the kind of work — manual override is always one tap away.
- 04
Stay with it
Fewer context breaks. Long passes of quiet attention. You leave when the work is done.
Sound that supports attention — not a player that demands it.
The Music Agent shapes ambience around what you’re doing: deep focus, debugging, exploration, late-night review. Switch sets, pause, or pin a mood — it stays out of the way.
- Adapts to session context — not your camera
- Manual mood pinning, always available
- Mixes designed for long passes of attention
Plan, run, and review coding tasks in a calm desktop window.
A native macOS surface for working with an agent: task framing, tool calls you can inspect, approvals you control, and a status line that tells you what’s actually happening.
- Inspectable tool calls
- Approvals before anything ships
- Status that respects your attention
Most tools help you write code. CodeNocturne helps you stay with it.
Writing the code is rarely the hard part. Holding the thread for two more hours is. CodeNocturne is built around the shape of a long, quiet session.
Fewer breaks in attention
Surfaces that keep one thread of work in view at a time.
A calmer interface for long sessions
Dark, quiet, low-contrast where it should be. Loud only where it matters.
Soundscapes shaped around your work
Not a playlist. An ambience that follows the session.
