Summarify

Summarify is an iOS and Mac app, also available as a Chrome extension, that condenses YouTube videos into text summaries so users can grasp the content without watching the full video. It uses ChatGPT and OpenAI's models to generate the summaries, offering a choice of styles such as simple, bullet-point, or detailed, depending on how much depth a user wants. Summaries include timestamps linked back to the moments they cover, along with chapter breakdowns and the ability to summarize a custom segment of a video rather than the whole thing. A built-in search lets users look across a video's transcript for specific topics, and a time-savings tracker shows how many hours a user has reclaimed by reading summaries instead of watching. Users can export summaries in PDF, Markdown, or plain text formats, and download full transcripts separately. A share extension lets people generate a summary for a YouTube video without leaving the YouTube app itself. Summarify is built for students and professionals who want to quickly extract the key points from lecture, tutorial, or interview videos rather than watching them in full. Because each summary request calls ChatGPT and longer videos are broken into roughly 10-minute chunks that each cost a separate request, the free tier only covers a single chunk before requiring payment.
