The feedback loop with an AI coding agent has always had a hidden tax: you generate output, then jump to a browser, a diff viewer, or a PDF reader to actually see what it made, then context-switch back to tell it what to fix. Factory's latest Desktop App update is designed to eliminate that entirely. Droid's output now lives right next to the session that produced it, and you can point at exactly what needs changing without ever typing a file path or section description.
The three-part loop: Preview, Refine, Ship
The update organizes around a tight workflow. Every artifact Droid produces can now be previewed inline:
- Documents, decks, spreadsheets, and PDFs open in a preview tab directly inside the app
- Live websites load in a built-in browser, side by side with the session that built them
- Code changes appear as a full file-by-file diff, so you know exactly what changed before anything ships
Whatever Droid produces, you can preview it directly where you're already working. That sounds like a small convenience, but for anyone who has spent time copy-pasting outputs between windows, it meaningfully changes the pace of iteration.
Design mode: click the thing you want changed
The more interesting addition is design mode. With design mode, you select an element directly in the preview and comment exactly what you want changed, with no need to explain which section or file you mean. It works both on live browser previews and on generated files like PDFs or presentations.
