How I Automated 9 YouTube Channels at ₹0/month

I run 9 YouTube channels that post daily. I don't 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.

The 9 Channels

The Stack (All Free)

• Script generation: Gemini API (free tier, 4-key rotation) + Ollama fallback
• Voice: Google Cloud TTS (Wavenet, free 4M chars/month)
• Images: Pexels API (free stock images)
• Video: MoviePy (Python library, 1080x1920 vertical)
• Upload: YouTube Data API v3 (free)
• Scheduling: macOS LaunchAgents (built-in, free)

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)

This avoids hitting rate limits on any single key.

Monthly Cost Breakdown

The Result

9 channels × 1 video/day = 270 videos/month. Zero effort after initial setup.
