How to Summarize YouTube Videos with ChatGPT (4 Methods)

The fastest way to summarize YouTube videos with ChatGPT is using a browser extension like "YouTube Summary with ChatGPT & Claude" that automatically extracts transcripts and sends them to ChatGPT. For videos without extensions, you can copy the transcript manually from YouTube and paste it into ChatGPT with a summarization prompt. Both methods work with free ChatGPT and improve significantly with GPT-4.

Method 4: ChatGPT API (For Developers)

Automate video summarization using the OpenAI API and YouTube Data API.

Basic Implementation Concept

# Conceptual workflow (pseudocode)
# 1. Get video transcript using youtube-transcript-api
# 2. Send transcript to OpenAI API
# 3. Receive and process summary

import openai
from youtube_transcript_api import YouTubeTranscriptApi

def summarize_video(video_id):
    # Get transcript
    transcript = YouTubeTranscriptApi.get_transcript(video_id)
    full_text = " ".join([t['text'] for t in transcript])
    
    # Send to ChatGPT API
    response = openai.ChatCompletion.create(
        model="gpt-4",
        messages=[
            {"role": "system", "content": "Summarize video transcripts."},
            {"role": "user", "content": f"Summarize: {full_text}"}
        ]
    )
    
    return response.choices[0].message.content

API Costs Consideration

GPT-4 vs GPT-3.5 for Video Summaries

We tested both models on the same set of video transcripts:

When to Use Each Model

Use GPT-3.5 (Free) When:

• Video is under 30 minutes
• Content is straightforward
• Speed matters more than depth
• You're on a free account

Use GPT-4 (ChatGPT Plus) When:

• Video is complex or technical
• You need high accuracy
• Content requires nuanced understanding
• Length exceeds 45 minutes

Common Issues and Solutions

Problem: Transcript Too Long for ChatGPT

I'll send this video transcript in 3 parts. After I send all parts, summarize the entire video.

Part 1 of 3:
[FIRST THIRD OF TRANSCRIPT]

This transcript is very long. First, identify the 5 most important 
topics covered, then I'll ask for details on specific sections.

Problem: Summary Misses Key Points

Summarize this video, making sure to capture:
- The main thesis (stated around 2:30)
- The 3-step framework discussed
- The case study about [specific topic]
- The controversial opinion at the end

Problem: ChatGPT Hallucinates Information

Summarize only information explicitly stated in this transcript.
Do not add external information or make assumptions.
If something is unclear, note it as "[unclear in transcript]".

Problem: Extension Not Working

Solutions:

1. 1.Refresh both YouTube and ChatGPT pages
2. 2.Check if ChatGPT is logged in
3. 3.Disable conflicting extensions
4. 4.Clear browser cache
5. 5.Try incognito mode

Best Practices for ChatGPT Video Summaries

1. Start Broad, Then Narrow

First: "Give me a one-paragraph overview"

Then: "Now list 7 key points"

Finally: "Explain point 3 in detail"

2. Specify Output Format

Format the summary as:
## Main Topic
[2-3 sentences]

## Key Points
- Point 1: [explanation]
- Point 2: [explanation]
...

## Actionable Takeaways
1. [action item]
2. [action item]

3. Include Context

This is a video about machine learning basics for beginners.
The speaker is a professor at MIT.
Summarize for someone with basic programming knowledge.

4. Request Timestamps (When Available)

The transcript includes timestamps. In your summary, reference
timestamps for the most important moments (e.g., "At 12:34, 
the speaker explains...").

For daily use, install an extension. For research or detailed analysis, combine NoteLM.ai's clean transcripts with ChatGPT's conversational analysis capabilities.

Quick Start:

1. 1.Install "YouTube Summary with ChatGPT & Claude" extension
2. 2.Keep ChatGPT open in a browser tab
3. 3.Navigate to any YouTube video
4. 4.Click the summary button
5. 5.Read your summary in 10-20 seconds
