KiWi233333/JiwuChat — reverse-engineered prompt

Build me a lightweight chat app like JiwuChat. I want it to feel polished on web and desktop, with a responsive mobile layout too.

Users should be able to register, log in, add friends, create group chats, send text, images, videos, files and voice messages, see read status, quote replies, mention people, recall messages and manage pinned or hidden chats. Add AI chat support for private chats and group bots, with settings for providers like DeepSeek, Gemini and Kimi. Include voice calls, video calls and screen sharing using WebRTC if possible.

Please include notifications, tray style reminders where supported, ringtone settings, do not disturb, light and dark themes, font settings, account security pages, device management, file download management, image preview and video playback.

Use Vue, Nuxt and Tauri since that fits the project. Add clean demo data and clearly mark where the separate backend API connects. Look up current docs online if needed.
