Content is uploaded faster than anyone can watch it. These apps extract the main points from any YouTube video instantly — and for breaking down videos, they can even beat ChatGPT. In this roundup, the picks get better with every entry.

The 7 Apps

Gravity Write

YouTube Summarizer

Extracts captions, then feeds your favourite AI

More than a summarizer. It pulls the captions from any video and hands them to tools like Claude, ChatGPT or Gemini for accurate summaries in seconds.

Get the app via the link, install the APK, then open YouTube
Tap Share on a video and select YouTube Summarizer
Share the transcript to Claude, Gemini, ChatGPT or Grok
The prompt is inserted automatically — edit it if you want

Claude is recommended for the most accurate and detailed summaries.

Video Summarizer

Summaries plus on-demand Q&A

Install it from the Play Store, copy a YouTube link, paste it in, and the summary appears. Then ask follow-up questions about the video and get instant answers based on its content.

The same question-and-answer feature also works in the earlier Gumroad app after you generate a summary in Claude.
