harriik/Jarvis — reverse-engineered prompt

Build me a Python desktop app like a Jarvis personal assistant for my laptop. I want it to open with a clean futuristic GUI, let a new user sign up, then log in with face recognition, username and password, or voice authentication.

After login, the assistant should listen for voice commands, talk back naturally, and help with normal daily tasks. It should tell me the weather and news, search and play YouTube videos, send emails, open websites like Gmail and WhatsApp, search files on my computer, launch apps, set reminders and alarms, and control system things like volume, brightness, window minimize, and basic OS commands.

Please also include webcam features for face recognition, object identification, and simple gesture controls like changing volume or navigating with hand movements. Make the code organized so each feature is in its own module, with a main app that connects everything together. Include setup instructions, requirements, and places to add API keys for weather, news, maps, and email. Look up current docs online if you need to.
