# 🤖 Manus AI Clone
An AI-powered browser automation system that replicates the functionality of [Manus.im](https://manus.im) and [Scout.new](https://scout.new). This application allows users to control a web browser using natural language prompts, powered by LangChain and OpenAI's GPT models.
## ✨ Features
- **Natural Language Browser Control**: Give instructions in plain English, and the AI will control the browser for you
- **LangChain Integration**: Uses LangChain agents with custom tools for browser automation
- **Playwright Browser Automation**: Full browser control with support for navigation, clicking, typing, and more
- **Real-time Screenshots**: See what the browser is doing with automatic screenshots
- **Action History**: Track all actions performed by the AI agent
- **Beautiful Web UI**: Modern, responsive interface for interacting with the system
- **RESTful API**: Programmatic access to browser automation capabilities
## 🛠️ Technology Stack
- **Backend**: FastAPI (Python)
- **AI Framework**: LangChain + OpenAI GPT models
- **Browser Automation**: Playwright
- **Frontend**: HTML/CSS/JavaScript (Vanilla)
- **Package Management**: UV
## 📋 Prerequisites
- Python 3.12+
- UV package manager
- OpenAI API key
- Chrome/Chromium browser (installed automatically by Playwright)
## 🚀 Quick Start
### 1. Clone and Setup
```bash
# Navigate to project directory
cd manus_ai_clone
# Create and activate virtual environment using uv
uv venv
source .venv/bin/activate # On Linux/Mac
# or
.venv\Scripts\activate # On Windows
# Install dependencies
uv pip install -e .
```
### 2. Install Playwright Browsers
```bash
# Install Playwright browser binaries
playwright install chromium
```
### 3. Configure Environment
```bash
# Copy the example environment file
cp .env.example .env
# Edit .env and add your OpenAI API key
# OPENAI_API_KEY=sk-your-actual-api-key-here
```
### 4. Run the Application
```bash
# Start the server
python main.py
# Or use uvicorn directly
uvicorn main:app --reload --host 0.0.0.0 --port 8000
```
### 5. Access the Application
Open your browser and navigate to:
```
http://localhost:8000
```
## 🎯 Usage Examples
### Via Web Interface
1. Open http://localhost:8000 in your browser
2. Enter a natural language prompt in the text area
3. Click "Execute Task"
4. Watch the AI control the browser and see the results
**Example Prompts:**
- "Go to google.com and search for 'LangChain tutorial'"
- "Navigate to github.com and find the trending repositories"
- "Open wikipedia.org and search for 'Artificial Intelligence', then read the first paragraph"
- "Go to hacker news and get the top 5 story titles"
- "Visit amazon.com and search for 'python books'"
### Via API
```bash
# Execute a browser automation task
curl -X POST "http://localhost:8000/execute" \
-H "Content-Type: application/json" \
-d '{"prompt": "Go to google.com and search for LangChain"}'
# Check health status
curl http://localhost:8000/health
# Get action history
curl http://localhost:8000/status
```
### Using Python
```python
import requests
# Execute a task
response = requests.post(
"http://localhost:8000/execute",
json={"prompt": "Go to github.com and search for 'langchain'"}
)
result = response.json()
print(f"Success: {result['success']}")
print(f"Output: {result['output']}")
# Screenshot is available as base64 encoded image
if result['screenshot']:
import base64
screenshot_data = base64.b64decode(result['screenshot'])
with open('screenshot.png', 'wb') as f:
f.write(screenshot_data)
```
## 🏗️ Architecture
### Components
1. **Browser Agent (`browser_agent.py`)**
- `BrowserController`: Low-level Playwright wrapper for browser operations
- `BrowserAgent`: LangChain agent with custom tools for AI-powered automation
2. **API Server (`main.py`)**
- FastAPI application with REST endpoints
- Lifecycle management for browser agent
- Web UI serving
3. **Tools Available to AI**
- `navigate`: Go to URLs
- `click`: Click elements by CSS selector
- `type_text`: Fill input fields
- `get_text`: Extract text from elements
- `get_page_content`: Read page content
- `scroll`: Scroll the page
- `get_elements_info`: Inspect elements
- `execute_javascript`: Run custom JavaScript
### How It Works
```
User Prompt → FastAPI → LangChain Agent → Tools → Playwright → Browser
↓ ↓
Response ← Agent Reasoning ← Tool Results ← Browser State
```
1. User submits a natural language prompt
2. LangChain agent breaks down the task into steps
3. Agent selects and executes appropriate tools
4. Playwright performs browser actions
5. Results are collected and returned with a screenshot
## ⚙️ Configuration
### Environment Variables
```bash
# Required
OPENAI_API_KEY=sk-your-api-key-here
# Optional
MODEL=gpt-4o-mini # OpenAI model to use
HEADLESS=false # Run browser in headless mode
HOST=0.0.0.0 # Server host
PORT=8000 # Server port
```
### Model Options
- `gpt-4o-mini` (default) - Fast and cost-effective
- `gpt-4o` - More capable, higher cost
- `gpt-4-turbo` - Advanced reasoning
## 🔧 Development
### Project Structure
```
manus_ai_clone/
├── main.py # FastAPI application
├── browser_agent.py # Browser automation logic
├── pyproject.toml # Dependencies
├── .env.example # Environment template
├── .gitignore # Git ignore rules
└── README.md # This file
```
### Adding Custom Tools
To add new browser automation capabilities:
1. Add a method to `BrowserController` class
2. Create a wrapper function in `BrowserAgent._create_tools()`
3. Add a `Tool` definition with name, function, and description
Example:
```python
# In BrowserController
async def custom_action(self, param: str) -> str:
# Your implementation
return "Result"
# In BrowserAgent._create_tools()
def custom_action_wrapper(param: str) -> str:
return asyncio.run(self.browser.custom_action(param))
# Add to tools list
Tool(
name="custom_action",
func=custom_action_wrapper,
description="Description of what this tool does"
)
```
## 🐛 Troubleshooting
### Common Issues
**Import errors about missing packages:**
```bash
# Packages not installed yet (errors are normal before installation)
uv pip install -e .
playwright install chromium
```
**"Browser agent not initialized":**
- Check that your `OPENAI_API_KEY` is set in `.env`
- Make sure the `.env` file is in the project root
**Playwright errors:**
```bash
# Reinstall Playwright browsers
playwright install --force chromium
```
**Element not found errors:**
- The AI might be using incorrect selectors
- Try being more specific in your prompt
- Some websites use dynamic class names or have anti-bot measures
**Timeout errors:**
- Some pages load slowly
- Try increasing timeout values in `browser_agent.py`
- Or use simpler websites for testing
## 🚀 Deployment
### Using Docker (Optional)
```dockerfile
FROM python:3.12-slim
WORKDIR /app
# Install system dependencies for Playwright
RUN apt-get update && apt-get install -y \
wget \
gnupg \
&& rm -rf /var/lib/apt/lists/*
# Copy project files
COPY . .
# Install Python dependencies
RUN pip install -e .
RUN playwright install --with-deps chromium
# Run the application
CMD ["python", "main.py"]
```
### Environment Setup for Production
```bash
# Use headless mode in production
HEADLESS=true
# Use a more capable model if needed
MODEL=gpt-4o
# Secure your API
# Consider adding authentication middleware
```
## 📊 Performance Tips
1. **Use headless mode** (`HEADLESS=true`) for faster execution
2. **Choose the right model**: `gpt-4o-mini` for speed, `gpt-4o` for complex tasks
3. **Be specific in prompts**: More detailed prompts = better results
4. **Set appropriate timeouts**: Adjust based on your target websites

# How It Works: Manus AI Clone - System Summary
## Overview
Manus AI Clone is an AI-powered browser automation system that allows users to control a web browser using natural language prompts. The system combines a modern web frontend, FastAPI backend, LangChain AI agent, and Playwright browser automation to create an intelligent system that can understand user intent and execute complex browser tasks.
### Key Technologies
- **Frontend**: HTML5, CSS3, Vanilla JavaScript
- **Backend**: FastAPI (Python)
- **AI Framework**: LangChain
- **Browser Automation**: Playwright
- **LLM**: OpenAI GPT models (gpt-4o-mini, gpt-4o, etc.)
---
## System Architecture
The system follows a layered architecture:
1. **Frontend Layer** - User interface for input and results display
2. **Backend API Layer** - FastAPI server handling HTTP requests
3. **Browser Agent Layer** - LangChain agent that plans and executes tasks
4. **Browser Control Layer** - Playwright for browser automation
---
## How It Works
### Frontend Layer
The frontend provides a web-based user interface where users can:
- Enter natural language prompts describing browser tasks
- View example prompts for quick reference
- See real-time loading indicators during task execution
- View results including:
- Success/error status
- Agent output messages
- Complete action history (all browser actions taken)
- Screenshot of the final browser state
- Track execution statistics (total tasks, success rate, average time)
When a user submits a task:
1. The JavaScript validates the input
2. Sends an HTTP POST request to the `/execute` endpoint with the prompt
3. Shows a loading indicator while waiting for the response
4. Upon receiving the response, displays all results in the UI
5. Updates statistics and shows notifications
Statistics are persisted in browser localStorage to maintain session data.
### Backend API Layer
The FastAPI backend serves multiple purposes:
**API Endpoints**:
- `GET /` - Serves the frontend HTML interface
- `POST /execute` - Main endpoint that executes browser automation tasks
- `GET /status` - Returns current browser state and action history
- `GET /health` - Health check endpoint
**Lifecycle Management**:
- On startup, initializes a single `BrowserAgent` instance
- Loads configuration from environment variables (OpenAI API key, model selection, headless mode)
- Manages browser agent lifecycle (startup and shutdown)
- On shutdown, properly cleans up browser resources
**Request Processing**:
When a task execution request is received:
1. Validates the request payload
2. Checks that the browser agent is initialized
3. Calls the agent's `execute_task()` method with the user's prompt
4. Formats and returns the response with success status, output text, screenshot, and action history
5. Handles errors appropriately with HTTP status codes
### Browser Agent Layer
The Browser Agent consists of two main components:
#### BrowserController (Low-Level Playwright Wrapper)
This component provides direct access to Playwright browser operations. It handles:
- Browser initialization (launching Chromium, creating context and page)
- Navigation to URLs
- Clicking elements by CSS selectors
- Typing text into input fields
- Extracting text from page elements
- Getting page content (title, URL, visible text)
- Taking screenshots
- Executing JavaScript on the page
- Finding and inspecting elements
- Scrolling the page
Every action is logged to an action history for transparency and debugging.
#### BrowserAgent (High-Level LangChain Agent)
This component uses LangChain to create an intelligent AI agent that can:
- Understand natural language prompts
- Break down complex tasks into steps
- Select appropriate tools for each step
- Execute tools in a logical sequence
- Reason about results and adjust actions accordingly
- Verify task completion
The agent has access to 8 tools that correspond to browser operations:
1. **navigate** - Go to URLs
2. **click** - Click elements by CSS selector
3. **type_text** - Fill input fields (uses format: "selector|text")
4. **get_text** - Extract text from specific elements
5. **get_page_content** - Read current page content
6. **scroll** - Scroll page in different directions
7. **get_elements_info** - Find and inspect elements
8. **execute_javascript** - Run custom JavaScript
Each tool has a detailed description that helps the AI agent understand when and how to use it. The agent uses these descriptions to select the right tool for each task.
**System Prompt**: The agent is given comprehensive instructions on how to approach tasks, when to use each tool, how to verify actions, and CSS selector usage.
**Async/Sync Bridge**: Since LangChain tools are synchronous but Playwright operations are async, wrapper functions use `asyncio.run()` to bridge this gap.
### Task Execution Flow
When a user submits a task like "Go to google.com and search for Python":
1. **Frontend** sends the prompt to the backend API
2. **Backend** receives the request and calls the agent
3. **Agent** analyzes the prompt and breaks it down:
- Navigate to google.com
- Understand the page structure
- Find the search input field
- Type "Python" into the search field
- Click the search button
- Verify the results
4. **Agent** selects and executes tools in sequence:
- Uses `navigate()` to go to Google
- Uses `get_page_content()` to understand the page
- Uses `get_elements_info()` to find the search input
- Uses `type_text()` to enter the search query
- Uses `click()` to submit the search
- Uses `get_page_content()` again to verify success
5. **Playwright** performs each browser action through the BrowserController
6. **Results** flow back to the agent after each tool execution
7. **Agent** reasons about the results and determines when the task is complete
8. **Screenshot** is captured of the final browser state
9. **Response** is assembled with success status, output message, base64-encoded screenshot, and action history
10. **Frontend** displays all results to the user
### Data Flow
The complete flow follows this pattern:
**User Input** → **Frontend JavaScript** → **HTTP POST Request** → **FastAPI Backend** → **LangChain Agent** → **Tool Selection** → **Playwright Browser Actions** → **Results Flow Back** → **Agent Reasoning** → **Screenshot Capture** → **Response Assembly** → **JSON Response** → **Frontend Display** → **User Views Results**
### Key Features
**Action History**: Every browser action is logged with details (action type, selectors, URLs, text entered, etc.). This provides full transparency of what the AI did.
**Screenshot Capture**: After task completion, a screenshot is taken and included in the response as a base64-encoded image, giving users visual confirmation of the results.
**Error Handling**: Errors are handled at every layer:
- Frontend catches network errors and displays user-friendly messages
- Backend validates requests and returns appropriate HTTP status codes
- Browser agent handles Playwright timeouts and element not found errors gracefully
**State Management**:
- Browser state persists between tasks (single browser instance)
- Frontend statistics persist in localStorage
- Action history accumulates throughout the session
**Modular Architecture**: Each layer is independent, making the system maintainable and extensible. New browser tools can be added by extending the BrowserController and creating corresponding tool wrappers.
---
## Summary
Manus AI Clone transforms natural language instructions into browser automation through a carefully orchestrated pipeline:
1. Users provide natural language prompts through a web interface
2. The FastAPI backend receives and validates requests
3. A LangChain AI agent interprets the task and plans a sequence of actions
4. The agent executes browser tools through Playwright
5. Results are collected, including screenshots and action history
6. Everything is displayed back to the user in the frontend
The system demonstrates how AI reasoning can be combined with browser automation to create an intelligent system that can interact with web pages just like a human would, but with the speed and consistency of automation.

## Code Comparison
### ❌ Before: main.py (Home Route)
```python
@app.get("/", response_class=HTMLResponse)
async def home():
"""Serve the frontend interface"""
html_content = """
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">

<script>
async function executeTask() {
// 200+ more lines of JavaScript
}
</script>
</body>
</html>
"""
return HTMLResponse(content=html_content)
```
**Problems:**
- ❌ 400+ lines in one function
- ❌ Mixed HTML, CSS, and JavaScript
- ❌ Hard to maintain
- ❌ No code reuse
- ❌ Difficult to customize
- ❌ Poor separation of concerns
### ✅ After: main.py (Home Route)
```python
# Setup templates (at top of file)
BASE_DIR = Path(__file__).resolve().parent
templates = Jinja2Templates(directory=str(BASE_DIR / "templates"))
# Mount static files
app.mount("/static", StaticFiles(directory=str(BASE_DIR / "static")), name="static")
# Clean, focused route
@app.get("/", response_class=HTMLResponse)
async def home(request: Request):
"""Serve the frontend interface"""
return templates.TemplateResponse("index.html", {"request": request})
```
**Benefits:**
- ✅ Only 4 lines for route
- ✅ Clean separation of concerns
- ✅ Easy to maintain
- ✅ Reusable templates
- ✅ Simple to customize
- ✅ Professional structure
## File Organization
### ❌ Before
```python
# Everything in main.py
def home():
html = """
<style>
.button { ... }
.card { ... }
/* 300 lines of CSS */
</style>
<div>
<!-- 200 lines of HTML -->
</div>
<script>
function executeTask() { ... }
function clearResults() { ... }
/* 200 lines of JavaScript */
</script>
"""
```
### ✅ After
```
templates/base.html → Common layout
templates/index.html → Page structure
static/css/style.css → All styles (organized)
static/js/main.js → All JavaScript (organized)
main.py → API routes only
```
## Customization Comparison
### ❌ Before: Changing Button Color
1. Open main.py
2. Find the inline CSS (line 100-something?)
3. Locate .btn-primary class
4. Edit color value in string
5. Hope you didn't break the HTML string
6. Restart server
### ✅ After: Changing Button Color
1. Open static/css/style.css
2. Edit CSS variable:
```css
:root {
--primary-color: #your-color;
}
```
3. Save (auto-reloads with --reload)
4. Done! (No server restart needed)
## Adding New Page
### ❌ Before
```python
@app.get("/about")
async def about():
html = """
<!DOCTYPE html>
<html>
<head>
<style>
/* Copy all CSS again */
</style>
</head>
<body>
<!-- Duplicate nav/footer -->
<div>About content</div>
<!-- Duplicate scripts -->
</body>
</html>
"""
return HTMLResponse(content=html)
```
**Issues:**
- Code duplication
- Inconsistent styling
- Maintenance nightmare
### ✅ After
**1. Create template:**
```html
{% extends "base.html" %} {% block content %}
<div class="container">
<h1>About</h1>
<p>About content</p>
</div>
{% endblock %}
```
**2. Add route:**
```python
@app.get("/about")
async def about(request: Request):
return templates.TemplateResponse("about.html", {"request": request})
```
**Benefits:**
- Inherits all styling
- Consistent nav/footer
- No duplication
- Easy to maintain
## Developer Experience
### ❌ Before
```
Problems:
- Syntax highlighting breaks in strings
- No IDE autocomplete for HTML/CSS/JS
- Hard to debug (everything is a string)
- No linting for frontend code
- Difficult to collaborate
- Merge conflicts on main.py
```
### ✅ After
```
Benefits:
- Full syntax highlighting
- IDE autocomplete works
- Easy debugging (separate files)
- Linting for HTML/CSS/JS
- Easy collaboration
- Clean git diffs
- Professional structure
```
## Statistics
### Before
- **1 file**: main.py (540 lines)
- **0 templates**
- **0 static files**
- **0 documentation**
### After
- **2 templates**: base.html, index.html
- **2 static files**: style.css (500 lines), main.js (300 lines)
- **4 documentation files**: FRONTEND.md, QUICKSTART.md, IMPLEMENTATION.md, architecture.html
- **1 setup script**: setup.sh
- **main.py**: 175 lines (65% reduction!)
## Feature Comparison

| ---------------- | ------------------- | ------------------------------- |
| Template System | ❌ Inline HTML | ✅ Jinja2 templates |
| CSS Organization | ❌ In Python string | ✅ Separate file with sections |
| JavaScript | ❌ In Python string | ✅ Separate file with functions |
| Reusability | ❌ Copy-paste | ✅ Template inheritance |
| Maintainability | ⚠️ Difficult | ✅ Easy |
| Customization | ⚠️ Edit strings | ✅ Edit CSS variables |
| Documentation | ⚠️ Basic README | ✅ Comprehensive guides |
| Setup | ⚠️ Manual | ✅ Automated script |
| Statistics | ❌ None | ✅ Persistent tracking |
| Notifications | ❌ Browser alerts | ✅ Toast notifications |
| Navigation | ❌ None | ✅ Professional navbar |
| Footer | ❌ None | ✅ Credits and links |
| Responsive | ⚠️ Basic | ✅ Mobile-optimized |
## Lines of Code
### Before
```
main.py: 540 lines (HTML+CSS+JS+Python mixed)
Total: 540 lines
```
### After
```
templates/base.html: 52 lines
templates/index.html: 125 lines

static/js/main.js: 348 lines
main.py: 175 lines (Python only)
Documentation: 1000+ lines
Total organized code: 1,273 lines
+ 1000+ lines documentation
= Professional, maintainable codebase!
```

return templates.TemplateResponse("custom.html", {"request": request})
```
### Adding Custom Styles
Add to `static/css/style.css`:
```css
.custom-class {
/* Your styles */
}
```
Or create a new CSS file and link in template:
```html
{% block extra_css %}
<link rel="stylesheet" href="{{ url_for('static', path='/css/custom.css') }}" />
{% endblock %}
```
### Adding Custom JavaScript
Add to `static/js/main.js` or create new file:
```html
{% block extra_js %}
<script src="{{ url_for('static', path='/js/custom.js') }}"></script>
{% endblock %}
```

- Collapsible navigation on mobile
## Customization
### Theming
Edit CSS variables in `style.css`:
```css
:root {
--primary-color: #667eea;
--secondary-color: #764ba2;
--success-color: #4caf50;
/* etc. */
}
```
### Adding New API Endpoints
```python
@app.get("/api/custom")
async def custom_endpoint():
return {"message": "Custom response"}
```
### Adding New Templates
1. Create template in `templates/`
2. Register route in `main.py`
3. Use `templates.TemplateResponse()`
## Development Tips
1. **Hot Reload**: Use `--reload` flag with uvicorn for development
2. **Debug Mode**: Check browser console for JavaScript errors
3. **Template Errors**: FastAPI shows detailed template errors in browser
4. **Static Files**: Changes to CSS/JS are cached - hard refresh (Ctrl+Shift+R)
## Browser Compatibility
- Chrome/Edge: ✅ Full support
- Firefox: ✅ Full support
- Safari: ✅ Full support
- Mobile browsers: ✅ Responsive design
## Performance Considerations
- Static files are cached by browser
- Screenshots are base64 encoded (may be large)
- Action history limited to prevent DOM bloat
- Statistics stored in localStorage (5-10MB limit)
## Security Notes
- CORS enabled for same-origin only
- No authentication included (add if exposing publicly)
- API keys loaded from environment variables
- User input sanitized by FastAPI/Pydantic
## Future Enhancements
Potential additions:
- Dark mode toggle
- Export results as PDF
- WebSocket for real-time updates
- User authentication
- Task history database
- Screenshot comparison
- Recording browser sessions
- Multi-language support

# LangChain v1.0 Migration Notes
## What Changed
The codebase has been updated to use **LangChain v1.0** API, which introduced breaking changes from v0.x.
## Key Changes Made
### 1. Agent Creation API
**Before (v0.x):**
```python
from langchain.agents import AgentExecutor, create_openai_tools_agent
from langchain_core.prompts import ChatPromptTemplate, MessagesPlaceholder
from langchain_core.tools import Tool
# Create tools as Tool objects
tools = [
Tool(name="navigate", func=navigate_wrapper, description="..."),
# ... more tools
]
# Create prompt with MessagesPlaceholder
prompt = ChatPromptTemplate.from_messages([...])
# Create agent and executor
agent = create_openai_tools_agent(llm, tools, prompt)
agent_executor = AgentExecutor(agent=agent, tools=tools, ...)
# Execute
result = await agent_executor.ainvoke({"input": task})
```
**After (v1.0):**
```python
from langchain.agents import create_agent
# Create tools as simple functions with docstrings
def navigate(url: str) -> str:
"""Navigate to a URL. Input should be a valid URL."""
return asyncio.run(self.browser.navigate(url))
tools = [navigate, click, type_text, ...] # Just functions!
# Create agent directly
agent = create_agent(
model="gpt-4o-mini",
tools=tools,
system_prompt="Your instructions here"
)
# Execute with messages format
result = await agent.ainvoke(
{"messages": [{"role": "user", "content": task}]}
)
```
### 2. Tool Definition
**Before:**
- Tools were defined as `Tool` objects
- Required explicit `name`, `func`, and `description` parameters
**After:**
- Tools are simple Python functions
- Function docstring becomes the tool description
- Function name becomes the tool name
- Much simpler and cleaner!
### 3. Response Format
**Before:**
```python
result = await agent_executor.ainvoke({"input": task})
output = result.get("output")
```
**After:**
```python
result = await agent.ainvoke({"messages": [{"role": "user", "content": task}]})
output = result["messages"][-1].content
```
### 4. Pydantic Models
Also updated Pydantic models to use v2.0 syntax:
**Before:**
```python
class Settings(BaseSettings):
field: str
class Config:
env_file = ".env"
```
**After:**
```python
from pydantic import ConfigDict
class Settings(BaseSettings):
model_config = ConfigDict(env_file=".env")
field: str
```
## Benefits of v1.0
1. **Simpler API**: Less boilerplate code
2. **Better Tool Definition**: Functions with docstrings vs Tool objects
3. **Built on LangGraph**: Better durability and streaming support
4. **Cleaner Code**: More intuitive and Pythonic
5. **Better Performance**: Optimized execution
## Migration Checklist
- [x] Replace `create_openai_tools_agent` with `create_agent`
- [x] Remove `AgentExecutor` usage
- [x] Convert `Tool` objects to simple functions
- [x] Update invocation format to use messages
- [x] Update response parsing
- [x] Fix Pydantic v2.0 deprecations
- [x] Test all functionality
## Running the Application
The application now works with LangChain v1.0:
```bash
# Install dependencies
uv pip install -e .
playwright install chromium
# Set up environment
cp .env.example .env
# Edit .env and add OPENAI_API_KEY
# Run
python main.py
```
## Documentation
- [LangChain v1.0 Overview](https://docs.langchain.com/oss/python/langchain/overview)
- [Migration Guide](https://docs.langchain.com/oss/python/migrate/langchain-v1)
- [Release Notes](https://docs.langchain.com/oss/python/releases/langchain-v1)
## Issues Fixed
- ✅ `ImportError: cannot import name 'AgentExecutor'` - Fixed by using new API
- ✅ Pydantic deprecation warnings - Fixed by using ConfigDict
- ✅ All imports working correctly
- ✅ Application runs successfully

## 🔧 Development Tips
1. **Auto-reload**: Use `uvicorn main:app --reload` for hot reloading
2. **Template errors**: Check FastAPI error pages for detailed info
3. **CSS changes**: Hard refresh (Ctrl+Shift+R) to bypass cache
4. **JS debugging**: Use browser DevTools console
5. **API testing**: Use `/docs` for Swagger UI
## 📱 Responsive Breakpoints
- Desktop: > 768px
- Tablet: 768px
- Mobile: < 768px
Customized layouts for each breakpoint in `style.css`.
## 🚀 Performance
- Static files cached by browser
- Minimal external dependencies
- Optimized animations (GPU-accelerated)
- Lazy loading for images
- Debounced events
## 📚 Resources
- [Jinja2 Documentation](https://jinja.palletsprojects.com/)
- [FastAPI Templates](https://fastapi.tiangolo.com/advanced/templates/)
- [Static Files](https://fastapi.tiangolo.com/tutorial/static-files/)
## 🐛 Troubleshooting
**Templates not loading?**
- Check `BASE_DIR` path in `main.py`
- Verify template files exist in `templates/`
**Static files 404?**
- Check static mount in `main.py`
- Verify files exist in `static/css/` or `static/js/`
- Use correct `url_for()` syntax
**JavaScript not working?**
- Check browser console for errors
- Verify API endpoints are responding
- Check CORS settings
**Styles not applying?**
- Hard refresh browser (Ctrl+Shift+R)
- Check CSS file path
- Inspect element in DevTools
