Inline Suggestions
Your agent proposes edits grounded in related specs and implementation. Accept, reject, or tweak each suggestion inline without leaving the document.
Documentation
Your workshop. Your tools. Your process.
Better specs lead to better code. But keeping specs sharp means holding a lot of context in your head: what related docs say, which tasks are in flight, what needs your attention next. Atelier is a VS Code extension that surfaces that context as you work.
-
A rich text editor where you write specs, shape plans, and maintain architecture docs. As you write, AI proposes suggested edits grounded in your entire repository, cross-referencing implementation, and other design docs before changing a single sentence.
-
A kanban board that gives you the spatial view. See what’s moving, what’s blocked, what needs your eye. Hover over a plan and watch its tasks light up. Every card is a file. Drag a task to a new column and it launches your agent with the right context.
Features
Section titled “Features”Visual Workflow
Every card on the board is a file in your repo. Hover over a plan to see its tasks light up. Drag a task to a new column to launch your agent with the right context.
Integrated Planning
Your agent helps decompose ideas into implementable tasks, walking through design decisions and defining acceptance criteria along the way. Each task appears on the kanban board, ready to be picked up.
Real-time Updates
The board updates automatically as your agent makes progress. When an agent needs approval or asks a question, you see it on the card and click through to the right terminal, even when multiple agents are running at once.
Verification Built-in
Spec-driven workflow: define acceptance criteria upfront, verify completed work at both task and plan levels. Failures become new tasks, not hidden tech debt.
Mermaid Diagrams
Plans and tasks can include Mermaid diagrams that render inline in the editor, so you can visualize architecture and flow alongside the spec that describes them.
Does Atelier cost money?
No. Atelier is free to use. If you use it with Claude Code, it will use your Claude Code subscription.
Is Atelier a separate app?
No. Atelier runs as a VS Code extension and uses files in your current workspace.
Do I need Claude Code to use Atelier?
Atelier is designed to work best with Claude Code, but you can customize it to work with other AI coding agents.
Where is my data stored?
All your data stays on your machine. Atelier indexes are in the .atelier directory in your home directory.
Does Atelier support Cursor?
Yes. You can install it from Open VSX for Cursor compatibility.
