Generative AI Switcher (Kotlin)

A Kotlin-based web application built with Spring Boot that allows you to switch between multiple Generative AI APIs (e.g., DeepSeek, ChatGPT, Claude) and customize AI settings. 🤖

The app features a clean and structured frontend with a side menu for AI parameters and a main content area for chat interactions.

---

Features

• Multi-Chat Sessions: Create, switch, and delete chat sessions.
• Customizable AI Settings: Adjust parameters like temperature, max_tokens, and top_p.
• Multiple APIs: Choose between different Generative AI APIs (DeepSeek, ChatGPT, Claude).
• Chat History: Stores chat sessions locally for retrieval and visualization.
• Clean JSON Serialization: Uses Kotlin data classes and Jackson for seamless API communication.

---

Technologies Used

• Backend: Spring Boot (Kotlin, v.2.0.10, java 21)
• Frontend: HTML, CSS (Bootstrap), JavaScript (to be perhaps replaced by React later on, but I am not a frontend dev)
• API Integration: DeepSeek, ChatGPT, Claude
• Build Tool: Gradle (v. 8.12)
