DownSub - Subtitle & Transcript Downloader: YouTube, Netflix

Download and display video subtitles from YouTube, Netflix, and more sites. Translate in real-time. Pro: AI summaries.

Download subtitles from YouTube, Netflix, and the other sites you watch in one click - SRT, VTT, or TXT - translate them to 100+ languages, and show the translation right on the video. DownSub adds a clean "Download" button right where you need it - next to the share/save bar or inside the player controls, styled to match each site. No URL copy-paste, no third-party sites. ━━━━━━━━━━━━━━━━━━━━━━━━━ WORKS EVERYWHERE YOU WATCH ━━━━━━━━━━━━━━━━━━━━━━━━━ The Download button appears automatically on every supported video page - including the major international streaming platforms for K-dramas, C-dramas, and anime. The full, up-to-date list of supported sites is at https://downsub.com. Two site-specific tips: • On some sites, start playback once so the player loads the subtitle tracks • A few sites only serve subtitles to signed-in viewers - sign in and reload the page if the widget asks ━━━━━━━━━━━━━━━━━━━━━━━━━ FREE FEATURES ━━━━━━━━━━━━━━━━━━━━━━━━━ • Download subtitles in SRT, VTT, plain text, or text-with-timestamps • Auto-translate captions to 100+ languages via the site's own translation engine where available - never costs credits • Full transcript panel with click-to-seek timestamps and live search • Dual subtitles: show two languages stacked on the player at once - perfect for language learners (works on every supported site) • Copy transcript to clipboard for notes, blogs, or LLM prompts • Smart filename: video title + language + format • Strip non-speech tags ([Music], [Applause], (laughs)…) for clean reading • Dark / light theme that follows the site's appearance • UI available in 36 languages ━━━━━━━━━━━━━━━━━━━━━━━━━ PRO FEATURES (with DownSub account) ━━━━━━━━━━━━━━━━━━━━━━━━━ • Auto-download every video you open - pick your preferred subtitle language once in Settings, then never click again. The file lands in Downloads while you watch. • AI Summary - bullet points with timestamps in your preferred language. Pick a style: timeline, key points, action items, technical, educational, movie/novel (with optional spoiler-free mode). Works on every supported site. • Translate subtitles on sites without native auto-translate - pick any target language, then choose your engine: on-device translation (free, no credits, powered by Chrome's built-in translator) or DownSub AI for higher quality. • Show subtitles on the video - overlay the chosen track (original or translated) directly on the player; translate once and keep watching (the result is reused, so re-showing never re-charges) • Comments analysis (YouTube) - sentiment breakdown, top topics with quotes, and highlighted top comments • AI subtitles for videos with no captions (YouTube) - transcribe the video's audio into a ready-to-download subtitle with AI, optionally translated to your language ━━━━━━━━━━━━━━━━━━━━━━━━━ WHO IT'S FOR ━━━━━━━━━━━━━━━━━━━━━━━━━ • Language learners watching K-dramas, C-dramas, anime, and Asian shows - translate the subtitle and show it (or both languages) right on the player • Students & researchers turning lectures into searchable notes • Content creators repurposing videos into blogs / scripts • Anyone who hates wading through 30-minute videos for 2 minutes of insight • Archive-builders who want a subtitle copy of every video they watch - set Auto-download once and let it run in the background ━━━━━━━━━━━━━━━━━━━━━━━━━ PRIVACY ━━━━━━━━━━━━━━━━━━━━━━━━━ DownSub only requests access to the supported video sites plus downsub.com - no <all_urls>, no tracking, no ads. Subtitles download straight from the video site to your machine, and on-device translation runs entirely in your browser (no credits, no upload). AI summary and AI translation run on DownSub's own servers; nothing is shared with third parties. DownSub is a first-party extension from the team behind downsub.com. ━━━━━━━━━━━━━━━━━━━━━━━━━ SUPPORT ━━━━━━━━━━━━━━━━━━━━━━━━━ Got a question, bug report, or feature request?
