Free YouTube video transcript in one click: text with timestamps, AI video summarizer and key takeaways, TXT/SRT download. Get the transcript of any YouTube video in one click, right next to the player. Read it, search it, copy it or download it, and get an AI summary with the key takeaways when there is no time to watch. No sign-up, no account, no credit card. HOW IT WORKS 1. Open a video on youtube.com 2. Click "Transcribe & summarize" in the panel beside the player 3. The text appears in a few seconds, with clickable timestamps FEATURES • The full text with timestamps: click a line and the player jumps to that moment • Search inside the text • Copy to the clipboard, or download as TXT, SRT subtitles or Markdown • AI summary and key takeaways • Chapters for longer talks and lectures • Flashcards and a quiz on sozai.app, for studying • Save to SozAI on the web for notes, a quiz and chat in your own library (free account) WHERE THE TEXT COMES FROM The extension reads the captions a clip already has, written by its author or generated automatically, so results are fast. When there are no captions, SozAI on the web can transcribe the audio itself, using your account's minutes. FREE TO USE A free monthly allowance on every browser, no sign-up needed. PRIVACY When you click the button, the extension sends our server the link to that one video and an anonymous install ID that counts the free allowance. There is no account and no personal data, and nothing about your browsing is collected. Each transcript is also published as a public page on our website, so it opens instantly the next time anyone asks for it.
