🤖 Part 1: Local AI Chatbot

Our chatbot is like a little robot friend living on your computer. You can:

• 💬 Chat with AI
  Type messages and get smart replies.
• 🖼️ Upload images
  Show the bot a picture—ask it questions about what it sees!
• 🔥 Runs locally with Google’s Gemma 3 4B model
  A “4B” model means it has 4 billion tiny “neurons.” It’s just the right size for your laptop.
• 🌡️ Adjustable temperature
  • Temperature controls how creative or predictable the AI is.
  • Low = safe, repeatable answers.
  • High = wild, creative answers.
• 🎛️ System prompts
  You can set a “system message” to tell the AI how to behave (fun, serious, etc.).
• 💾 Chat memory
  The AI remembers recent messages so it can keep the conversation going.
• 🎨 JavaFX UI
  A simple, clean window to chat—no complicated menus.

Everything runs in User.db, our little database file that stores chat history only.
No user accounts yet—just your friendly chats!

📒 Part 2: SimpliNote Productivity App

This part is a group project by Akshita D., Harshil R., Prithvi S., and me (saltypal). It helps you plan your day easily:

• 📅 Calendar
  See your month in a neat grid.
• ✅ To-Do List
  Add tasks, set priorities (low ➖, medium ⚡, high 🔥), mark them done.
• ⏲️ Pomodoro Timer
  Work in sprints (25 minutes), then take a break.
• 🧠 Smart Note-Taking with local AI
  Write notes, ask the AI for summaries or insights. All happens on your computer—no cloud needed!

SimpliNote uses LangChain4j, a helper library that makes AI features easier to add in Java desktop apps.
