If you want to spend less time watching YouTube videos but still get the gist of what's going on, Eightify is a good choice. The AI-powered service offers key ideas and summaries instantly, and in more than 40 languages. It also offers TLDR summaries, timestamped breakdowns and the ability to upload your own video for summarization, all through extensions for iOS, Chrome and Safari.
Another good option is Video Highlight. It offers AI-generated summaries and transcripts, a chat interface for live Q&A, and integration with the note-taking tool Notion. Its smart search and ability to export summaries to Notion or Readwise means you can find and analyze videos more easily, for example to research markets or quickly understand what's going on.
