How I Automated 9 YouTube Channels at ₹0/month

#automation #python #youtube #ai

I run 9 YouTube channels that post daily. I dont touch any of them. Total cost: ₹0.

The Architecture

Topic CSV → AI Script (Gemini/Ollama) → Google TTS → MoviePy Video → YouTube Upload

All scheduled via Mac LaunchAgents. Each channel has its own plist file that triggers at a specific time.

Key Trick: 4-Key Rotation

import random

API_KEYS = [
    "key_1_from_project_A",
    "key_2_from_project_B",
    "key_3_from_project_C",
    "key_4_from_project_D",
]

def get_api_key():
    return random.choice(API_KEYS)
