genspark-ai/genoffice ? reverse-engineered prompt

Build me an AI powered office suite for macOS and Windows that feels like one app with four main tools, a document editor, spreadsheet editor, presentation editor, and PDF viewer. I want the apps to share a common shell, recent files, and the same AI side panel, with editing that can update selected content instead of rewriting the whole file. The docs app should open and save Word files without breaking formatting, the sheets app should handle Excel files well, the slides app should edit presentations, and the PDF app should support viewing, annotations, forms, stamps, signatures, and page actions.

Please keep it as a desktop Electron app with a clean modern interface, and make sign in work through a Genspark account so no local model API key is needed. If you need current library details or docs, look them up online. I mainly want a working version that can be run locally in development, with clear tests and a path to building signed installers for macOS and Windows.
