ChatPanel.tsx - Sidian

import { useState, useEffect } from 'react';
import { motion } from 'framer-motion';
interface Message {
  id: string;
  content: string;
}
const useChatMessages = (initialMessages: Message[]) => {
  const [messages, setMessages] = useState(initialMessages);
  const [isLoading, setIsLoading] = useState(false);
  return { messages, setMessages, isLoading };
}

export function ChatPanel() {
  const { messages } = useChatMessages([]);

Project Memory

Every requirement is stored and searchable

Memories capture stakeholder preferences, architectural decisions, and TODOs so the assistant always responds with context.
