Code editor
Edit code yourself in Machine Code, with language smarts, project search, and inline AI.
Machine Code has a full code editor, so you can make your own changes next to the agent's without switching apps.
Open a file
- Click a file in Files (Ctrl+Shift+E).
- Press Ctrl+P and type part of a file name.
- Click a file name in an agent's reply.
The file opens in its own tab, with the project's files on the right.
Save with Ctrl+S (⌘S on Mac).
Language smarts
TypeScript and JavaScript work out of the box. For other languages, Machine
Code uses the language server already on your computer when it finds one, for
example pyright for Python, gopls for Go, or rust-analyzer for Rust.
For JSON, CSS, and HTML, install vscode-langservers-extracted.

Inline AI
Press Ctrl+K (⌘K on Mac) inside the editor to ask for an edit right where you are.
| Action | What it does |
|---|---|
| Generate edit | Write an instruction, for example make this function async. The change shows as a diff you accept or reject. |
| Fix | Fixes the selected code, or the current line. |
| Explain | Explains the selected code, or the current line. |
| Ask agent | Sends the code and your question to a chat. |
While you type, the editor can also suggest the next few lines in grey. Press Tab to accept a suggestion.
Inline AI uses Machine models and your Machine credits. To change it, open Settings › Inline AI:
| Setting | What it does |
|---|---|
| Completions while typing | Turns the grey suggestions on or off. |
| Typing pause | How long you pause before a suggestion appears. |
| Completion model | The model for suggestions while you type. Pick a fast one. |
| Edit model | The model for Generate edit, Fix, and Explain. |
