Summify AI is a Chrome extension that uses ChatGPT to generate summaries of YouTube videos. It integrates directly into the YouTube interface and adds a summarization button that appears when watching any video on the platform. The extension is designed for viewers, students, professionals, and content creators who want to extract key information from video content without watching the full duration.
Key Features
- Instant video summaries: generates an overview of any YouTube video in approximately 3 seconds using ChatGPT, giving users the core ideas without watching the entire video
- Timestamped summaries: summarizes specific sections of a video and provides clickable timestamps to jump directly to relevant moments, skipping unnecessary parts
- Custom ChatGPT prompts: allows users to create, save, and reuse personalized prompt templates for extracting specific types of information from videos, such as book mentions, key people, or actionable steps
- Inline Q&A: users can ask ad-hoc questions about a video content and receive immediate answers based on the transcript, without needing to rewatch segments
- Transcript search: searches the full video transcript for any word or phrase and navigates directly to matching timestamps, useful for navigating long interviews, podcasts, or lectures
- Full transcript access: copies and saves the entire video transcript with a single click for offline reference or further analysis
- Summary coverage tracker: displays how much of the video ChatGPT can summarize based on current token limits, giving users visibility into the completeness of summaries
- Multiple ChatGPT model selection: users can choose from different ChatGPT models to customize the summarization process to their needs
