VideoCore YouTube Downloader — Transcripts, Comments, Thumbnails

Download transcripts, comments & thumbnails from any YouTube video — or every transcript in a playlist, Watch Later or channel.

One extension, one job: save what is already on the YouTube page you're looking at — as a file. ▸ TRANSCRIPT DOWNLOADER Copy or download any video's transcript — .txt, .srt or Markdown, with or without timestamps. Works on any video with captions, including Shorts. ▸ BULK TRANSCRIPTS (new) Open a playlist, your Watch Later, or a channel's Videos tab and click "All transcripts ↓". The extension visits each video in turn — visibly, in your tab, cancellable at any time — and collects every transcript into a single Markdown or text file. Up to 100 videos per run. Perfect for studying a channel's scripts, building a research corpus, or archiving your own. ▸ COMMENTS DOWNLOADER Export the comment section of any video — CSV for spreadsheets, or plain text/Markdown — with authors, likes and replies as YouTube shows them. ▸ THUMBNAIL DOWNLOADER Every real size up to full HD (1280×720), probed so you never save a placeholder. One click. Turn each tool on or off from the extension popup — only the buttons you use appear on the page. PRIVATE BY DESIGN No account. No sign-up. No analytics. The extension makes no network requests of its own — it reads what YouTube has already rendered in your browser, and everything stays on your machine. Full policy: https://videocore.uk/extension-privacy-toolkit.php Built by VideoCore (videocore.uk) — the YouTube creator operating system. If you want scores and fixes on every video rather than downloads, try our VideoCore Lens extension instead.
