Here’s a clean, production-ready README.md for your project chatgpt-clone based on your branching chat implementation.

You can copy-paste this directly into README.md.

💬 ChatGPT Clone

A modern ChatGPT-style conversational UI built with Next.js (App Router) that supports:

• 🌳 Conversation tree (branching chat history)
• ✏️ Edit previous prompts (creates new branches)
• 🔀 Variant navigation (← → between sibling branches)
• 🧠 Active path rendering (ChatGPT-like behavior)
• ⚡ Built with React + TypeScript + Tailwind + shadcn/ui

---

✨ Features

🌲 Conversation Branching

• Every message is stored as a tree node
• Editing a prompt creates a new branch
• No conversation history is lost

🔁 Variant Navigation

• Navigate between sibling branches
• Displays current / total variant indicator
• Automatically resolves the deepest active path

🧭 Active Path Rendering

• Only the currently selected branch path is rendered
• Clean and predictable ChatGPT-like UX

🎨 Modern UI

• Built with:

  • Next.js App Router
  • TypeScript
  • TailwindCSS
  • shadcn/ui
  • Lucide Icons

🏗 Architecture

Conversation Model (Tree-Based)

Each message turn:

type Turn = {
  id: string
  parentId: string | null
  prompt: string
  response: string
  createdAt: number
  updatedAt: number
}

Instead of storing messages linearly, the app builds a:

Root
 ├── Variant A
 │     ├── Reply A1
 │     └── Reply A2
 └── Variant B
       └── Reply B1

🔄 How Branching Works

Editing a Prompt

• Creates a new Turn
• Uses the same parentId
• Generates a new assistant response
• Sets the new branch as active

Navigating Variants

• Finds sibling turns
• Moves to previous or next variant
• Resolves deepest child path
• Updates activeLeafId

---

🧠 Core Concepts

• turns → All conversation nodes
• activeLeafId → Current visible conversation endpoint
• visibleTurns → Path from root → active leaf
• childrenByParent → Map of siblings
• turnById → Fast lookup map

---
