Code Editor client-side ?
How to use Code EditorThis code editor runs entirely in your browser, powered by VS Code's editing engine (Monaco): syntax highlighting for ~80 languages, multi-cursor, find & replace, minimap. Open a full folder from your computer: on Chrome and Edge the editor reads and writes directly to your disk (save with Ctrl+S like a desktop editor); on Firefox and Safari the folder is read in full and you get your changes back via download or a ZIP export of the project. Search sweeps every text file in the project.
The AI panel opens Claude, ChatGPT or Gemini in a side window — with your own account — and a button copies the current file or selection, ready to paste as context. The key point: your files never leave your machine. Nothing is uploaded, no account required, usable on any computer — ideal on the go, at a client's office or on a loaner machine.

Frequently asked questions
Are my files uploaded to a server?
No, never. The editor runs entirely in your browser: reading, editing, search and saving all happen on your machine. You can verify it in your browser's network tab.
Which browsers can save directly to disk?
Chrome and Edge (File System Access API): Ctrl+S writes straight to the file on your disk. On Firefox and Safari you can read the whole folder, but saving goes through a download or a ZIP export.
Which languages are highlighted?
Around 80 languages via VS Code's engine: JavaScript/TypeScript, Python, Go, Rust, PHP, HTML/CSS, JSON, YAML, SQL, Markdown, shell and many more.
How does the AI panel work?
It opens Claude, ChatGPT or Gemini in a window next to the editor (using your existing account), and a button copies the file or selection formatted and ready to paste as context.
