YouTube Daily Digest: Auto Monitor & Summary 🥥Meow

A Python bot that monitors YouTube channels via RSS, summarizes new videos using Google Gemini AI (with audio fallback for videos without subtitles), and sends bilingual (Chinese + English) summaries to a Telegram chat daily.

YouTube 每日视频总结 Telegram 机器人

This skill deploys a YouTube monitoring bot that:

1. Polls configured YouTube channels via RSS feed (no API key needed for this step)
2. Extracts video transcripts using youtube-transcript-api
3. Falls back to audio download via yt-dlp if no subtitles are available
4. Summarizes content using Google Gemini 2.5 Flash (supports both text and audio input natively)
5. Sends a beautifully formatted bilingual (Chinese + English) summary to Telegram

Prerequisites

You need these three secrets configured in your environment:

• GEMINI_API_KEY — from Google AI Studio
• TG_BOT_TOKEN — from Telegram @BotFather
• TG_CHAT_ID — your personal or group Telegram chat ID

File Structure

File	Purpose
config.py	All configuration, API keys, and YouTube channel settings
youtube_monitor.py	RSS polling and local deduplication via db.json
extractor.py	Transcript fetching or audio download fallback
ai_summarizer.py	Gemini API integration (text + audio)
tg_notifier.py	Telegram message delivery with chunking
main.py	Main entry point with daily 8:00 AM scheduling
requirements.txt	All Python dependencies

Setup & Usage

Step 1: Configure channels and secrets

Edit config.py and add your API keys and the YouTube Channel IDs you want to monitor:

YOUTUBE_CHANNELS = {
    "UCxxxxxxxxxxxxxxxxxxxxxx": "Channel Name Here"
}

Step 2: Install dependencies

pip install -r requirements.txt

Step 3: Run

For a one-off immediate check:

python main.py

For long-running background mode (runs daily at 8 AM Izmir time):

nohup python main.py > bot.log 2>&1 &

How to Find a YouTube Channel ID

1. Go to the YouTube channel page
2. Click the channel name, then go to About
3. Click "Share Channel" and copy the link — the ID starts with UC...
4. Or use commentpicker.com/youtube-channel-id.php

Notes

• The bot tracks processed videos in db.json so it never sends duplicate summaries
• If Gemini API is not configured, the bot will fail gracefully with a clear error message
• Long videos with audio fallback may take 1–2 minutes to upload and process
