TranscriptTube

One-click YouTube transcript: read along, jump by timestamp, translate, AI summary, export .txt/.srt. No account.

TranscriptTube puts a small button above the suggested videos on every YouTube watch page (and a circle above the like button on Shorts). One click, and the full transcript of the video opens right there — no copying URLs, no external websites, no accounts. EXTRACT — in one click • Works on any video with subtitles or auto-captions • Works on Shorts too — transcript button above the like button • All available languages detected automatically • Consecutive duplicate caption lines removed automatically SUMMARIZE — with AI (optional) • One click summarizes the video: TL;DR, key points, chapters • Duration-aware: short videos get crisp key points, long videos get a chapter-by-chapter breakdown (very long ones are summarized in parts, then merged) • Timestamps in the summary are clickable — jump straight to any moment • Runs on OpenRouter's free models: paste your own free API key once • Free models can be busy at times — if a summary fails, try again shortly • The key is stored only in your browser and sent only to openrouter.ai READ — like a teleprompter • Timestamped lines: click any time to jump the video to that exact moment • Follow mode (toggle on/off): the spoken line is highlighted and the panel auto-scrolls as the video plays — perfect for studying and language learning TRANSLATE — into ~150 languages • Machine translation via YouTube's own translation service • Timestamps stay in sync — seek and Follow keep working on translated text • YouTube sometimes limits translation requests. The extension retries automatically; if it is still limited, try again in about a minute EXPORT — your way • Copy the transcript to the clipboard • Preview the .txt file content before downloading • Download as .txt (clean paragraphs) or .srt (standard subtitle file that works in VLC, Premiere, CapCut, and every video editor) PRIVATE BY DESIGN • No account, no analytics, no tracking • By default the extension talks only to YouTube, the same way the page itself does • The optional AI summary uses YOUR OWN OpenRouter key, stored locally. The transcript goes to OpenRouter and its AI model providers only when you ask for a summary, and their own privacy terms apply • The transcript is never stored; it exists only in your browser until you copy or download it Keyboard accessible, dark UI matching YouTube, works on watch pages, Shorts and live URLs. NOTES: videos with captions disabled by their creator cannot be extracted. Timestamps cannot move the video while a YouTube ad is playing.
