AIApplication

AI Tools is a cross-platform mobile application built with .NET MAUI that provides a unified interface to interact with multiple AI models including DeepSeek, Doubao, and Qwen. It supports text conversations, image and file attachments, user authentication, profile management, chat history persistence, and a model showcase gallery.

Features

• Multi-Model Chat – Switch seamlessly between DeepSeek, Doubao, and Qwen.
• Rich Attachments – Send images (supported by Doubao & Qwen) and text files (e.g., PDF, TXT, JSON) as context.
• Chat History – Conversations are automatically saved and grouped into topics. Browse all past topics and continue any conversation.
• User Authentication – Register with email verification code, login, and manage your personal profile.
• Profile Management – Upload avatar, set display name, gender, bio, and phone number.
• Model Square – Browse 8 popular AI models (Claude, ChatGPT, Gemini, DeepSeek, Qwen, Doubao, Grok, Kimi) with detailed specs, capability radar, pricing, and user reviews.
• Secure API Integration – All API keys are stored on the client (for demonstration). For production, use a backend proxy to keep keys secure.

Backend Dependencies

This app expects a backend server with the following endpoints (Spring Boot based):

• Authentication GET /Users/selectByUsername?username=xxx POST /Users/insertUser
• Chat GET /Topics/selectByUserId?userId=xxx POST /Topics/insertTopics GET /Topics/incrementMessageCount?id=xxx POST /ChatMessage/insertChatMessages GET /ChatMessage/selectByTopicId?topicId=xxx GET /ChatMessage/deleteByTopicId?topicId=xxx GET /Topics/deleteByUserId?userId=xxx
• Email Verification POST /api/v1/email/send-code POST /api/v1/email/verify-code
• User Profile & Avatar POST /UserProfiles/insertUserProfiles GET /UserProfiles/selectById?userId=xxx POST /UserProfiles/upload (multipart/form-data) GET /UserProfiles/addHeadImage?userId=xxx&avatarUrl=xxx GET /UserProfiles/download?name=xxx

The backend base URL is configured in ApiConfig.cs (default: http://your-server-ip-or-domain:port). Replace it with your own server address.

Getting Started

Prerequisites

• .NET 8 SDK or later
• Visual Studio 2022 (17.8+) / VS Code with MAUI workloads
• Android/iOS/macOS/Windows development environment (depending on your target)

Clone the Repository

git clone https://github.com/Nathan-code-development/AIApplication.git
cd AITools

Configure API Keys (Important)

The file Services/AiApiService.cs contains hardcoded API keys for demonstration. Do not commit real keys to GitHub. Instead, replace them with your own keys or use a secure configuration system.

private const string DeepSeekApiKey = "your-deepseek-key";
private const string DoubaoApiKey = "your-doubao-key";
private const string QianwenApiKey = "your-qianwen-key";

Alternatively, move keys to appsettings.json and use a configuration builder.

Update Backend URL

Edit Services/ApiConfig.cs:

public const string BaseUrl = "http://your-server-address:port";

Build and Run

• Open the solution in Visual Studio
• Select a target (e.g., Android Emulator, Windows Machine)
• Press F5 to debug

Security Notes

• API keys are currently hardcoded – only use this approach for personal/local testing.
• For production, move keys to a secure backend proxy or use Azure Key Vault / environment variables.
• Passwords are compared as plain text in the current demo backend. In a real application, always hash passwords.
