Pls suggest a good video summarizer ai tool for youtube

Honestly, I got tired of those “AI summarizer” extensions that either stop working, limit you after three uses, or require sign-ins everywhere.

So I started doing it the nerdy way — with command-line tools and a bit of Python.
Here’s how I built my own little workflow to summarize YouTube videos fast and privately, without depending on any Chrome add-ons.

(1) Command-line method with yt--dllp + whisper + ChatGPT

If you like keeping things local, this combo is gold.

Steps:

yt---dilp -x --audio-format mp3 https://www.youtube.com/watch?v=xxxx whisper video.mp3 --model small

That gives you a full transcript.
Then just paste it into ChatGPT (or Claude) and ask:

“Summarize the key points and main ideas.”

✅ Pros: Totally offline, accurate, and private.
⚠️ Cons: Needs Python setup — takes a few minutes at first.

This setup basically turns your PC into a small video summarizer ai, no browser plugins needed.

(2) Python automation method

If you want your own local video summarizer ai, you can automate it with the YouTube Transcript API + OpenAI.

from youtube_transcript_api import YouTubeTranscriptApi import openai transcript = YouTubeTranscriptApi.get_transcript("video_id") text = " ".join([t['text'] for t in transcript]) response = openai.ChatCompletion.create( model="gpt-3.5-turbo", messages=[{"role": "user", "content": f"Summarize this video:\n{text}"}] ) print(response["choices"][0]["message"]["content"])

✅ Pros: You control everything — format, tone, and detail level.
⚠️ Cons: Needs an API key and some Python basics.

I’ve been using this for long tech talks and tutorials — once it’s running, it feels like having your own video summarizer ai that listens and writes summaries just the way you want.
