Summarize YouTube Videos & Chat About Content with GPT-4o-mini via Telegram

Description

This n8n workflow automates the process of summarizing YouTube video transcripts and enables users to interact with the content through AI-powered question answering via Telegram. It leverages the GPT-4o-mini model to generate summaries and provide insights based on the video’s transcript.

How It Works

1. Input: The workflow starts by receiving a YouTube video URL. This can be submitted through:

   • A Telegram chat message.
   • A webhook (e.g., triggered by a shortcut on Apple devices).

2. Transcript Extraction: The URL is processed to extract the video transcript using the custom youtubeTranscripter community node (available here). The transcript is concatenated into a single text and stored in a Google Docs document.

3. Summarization: The GPT-4o-mini AI model analyzes the transcript and generates a structured summary, including:

   • A general overview.
   • Key moments.
   • Instructions (if applicable).
     The summary is then sent back to the user via Telegram.

4. Interactive Q&A: Users can ask questions about the video content via Telegram. The AI retrieves the stored transcript from Google Docs and provides accurate, context-based answers, which are sent back through Telegram.

Setup Instructions

To configure this workflow, follow these steps:

1. Import the Workflow: Download the provided JSON template and import it into your n8n instance.
2. Install the Community Node: Install the youtubeTranscripter community node via npm:

   npm install n8n-nodes-youtube-transcription-kasha
   

   Important: This node requires a self-hosted n8n instance due to its external dependencies.
3. Configure Nodes:
   • Webhook: Set up the webhook to receive YouTube URLs. Alternatively, configure the Telegram node if using Telegram as the input method.
   • Google Docs: Provide valid credentials to enable writing the transcript to a Google Docs document.
   • AI Model: Set up the GPT-4o-mini model for summarization and Q&A functionality.
4. Test the Workflow: Send a YouTube URL via your chosen input method (Telegram or webhook) and confirm that the summary is generated and delivered correctly.

Customization

• Language: Adjust the AI prompts to generate summaries and answers in any desired language.
• Output Format: Modify the summary structure by editing the prompt in the summarization node.
• Input Methods: Replace the Telegram node with another messaging or input node to adapt the workflow to different platforms.
