I want a cute web app that feels like using a real phone, but it is centered around AI characters. The main experience should be chatting with characters one on one or in group chats, with editable messages, retry, delete, different chat modes, and per chat scene settings like location and notes that get used as context. I also want character management, so I can create characters, edit them, import and export character cards, attach memory and world book style data, and remove chat threads when needed.

Please also include the phone style home screen with apps like contacts, social posts and comments, and a wallet view for me and for characters. Add backup and restore for app data, plus chat import and export. A settings area should let me switch AI providers and models, including custom endpoints, and ideally support common providers like OpenAI, Claude, Gemini, DeepSeek, Grok, OpenRouter, Ollama, NovelAI, and custom ones. Keep the style playful and polished, with themes, custom CSS support, and the little pet or desktop pet features if possible. Look up current docs online if you need to.
