Get started.

  1. Download and extract the extension ZIP. Open chrome://extensions, enable Developer mode, choose Load unpacked, and select the extracted folder.
  2. Open the extension workspace from the toolbar.
  3. Open File Explorer, create a file, and try a small project. Files stay in this extension’s local browser storage.

External service access follows the permissions you grant in Chrome. Manual installs need a download and reload for updates. A Chrome Web Store listing will provide standard installation and automatic updates.

  • Chat and a file explorer in one workspace, with clickable file paths in replies.
  • Edit text files, save changes, and preview HTML with unsaved CSS and JavaScript files. Dirty tabs offer Save, Discard or Cancel when closed.
  • Check syntax and format HTML, JavaScript, JSON and CSS. Formatting in the editor stays a draft until you save.
  • More reliable agent commands: multiline exec blocks, literal replacements, syntax diagnostics and clearer command results.
  • Simpler Settings: the shell/filesystem mode selectors and per-tier backend overrides are hidden. BYOM provider settings remain available for beta testing.
  • Import supported text/code files into local folders without overwriting existing names. Browser clients can export the current file, including an unsaved draft.
  • Token exhaustion during agent follow-ups can continue in Economy without rerunning completed file commands. Other request limits remain visible.
  • Downloaded chat transcripts include available tool receipts and distinguish proposed commands from recorded execution.
  • Files stay in the current client’s browser storage; signing in does not sync local workspace files between clients.
  • Bundled local file tools, syntax checks and formatting work offline. Hosted chat and online services need a connection.
