WhatsApp Message Scheduler

This demo requires browser-use v0.7.7+.

Features

1. Agent logs into WhatsApp Web automatically
2. Parses natural language scheduling instructions
3. Composes personalized messages using AI
4. Schedules messages for future delivery or sends immediately
5. Persistent session (no repeated QR scanning)

Setup

Make sure the newest version of browser-use is installed:

pip install -U browser-use

Export your Gemini API key, get it from: Google AI Studio

export GOOGLE_API_KEY='your-gemini-api-key-here'

Clone the repo and cd into the app folder:

git clone https://github.com/browser-use/browser-use.git
cd browser-use/examples/apps/msg-use

Initial Login

First-time setup requires QR code scanning:

python login.py

• Scan QR code when browser opens
• Session will be saved for future use

Normal Usage

1. Edit your schedule in messages.txt:

- Send "Hi" to Magnus on the 13.06 at 18:15
- Tell hinge date (Camila) at 20:00 that I miss her
- Send happy birthday message to sister on the 15.06
- Remind mom to pick up the car next tuesday

2. Test mode - See what will be sent:

python scheduler.py --test

3. Run scheduler:

python scheduler.py

# Debug Mode - See the browser in action
python scheduler.py --debug

# Auto Mode - Respond to unread messages every ~30 minutes
python scheduler.py --auto

Programmatic Usage

import asyncio
from scheduler import schedule_messages

async def main():
    messages = [
        "Send hello to John at 15:30",
        "Remind Sarah about meeting tomorrow at 9am"
    ]
    await schedule_messages(messages, debug=False)

asyncio.run(main())

Example Output

The scheduler processes natural language and outputs structured results:

[
  {
    "contact": "Magnus",
    "original_message": "Hi",
    "composed_message": "Hi",
    "scheduled_time": "2025-06-13 18:15"
  },
  {
    "contact": "Camila",
    "original_message": "I miss her",
    "composed_message": "I miss you ❤️",
    "scheduled_time": "2025-06-14 20:00"
  },
  {
    "contact": "sister",
    "original_message": "happy birthday message",
    "composed_message": "Happy birthday! 🎉 Wishing you an amazing day, sis! Hope you have the best birthday ever! ❤️🎂🎈",
    "scheduled_time": "2025-06-15 09:00"
  }
]
