Cypher1984GIT/omni ? reverse-engineered prompt

Build me a desktop app called Omni that lets me use several AI assistants in one place instead of jumping between a bunch of browser tabs.

I want a clean workspace where I can open different AI services, switch between them easily, reload or close them, and keep each one in its own persistent session so logins and state survive when I reopen the app. It should feel fast and simple, with a layout that gives as much room as possible to the chats, and it should handle loading problems or blocked pages with a nice retry message instead of just breaking.

Please include support for the main assistants people actually use, plus a private mode for services that need it. Make the app work as a cross platform Electron desktop app, keep cookies and settings stored locally, and make sure light and dark themes stay in sync inside the embedded views. If you need to check current docs or best practices while building it, go ahead and look them up online.
