Bilingual captions on the player
A Relingo-style dual-subtitle overlay sits on the YouTube player so you can read the original line and a translation without leaving the video.

What TalkClips Captions does
Bilingual captions, transcripts, and Word Coach on YouTube
≡
Synced transcript sidebar
A scrollable transcript follows playback. Click a cue to seek. Keep your place when you pause to study a sentence.
Aa
Word Coach on any caption word
Click a word in the overlay or sidebar to open Word Coach: definition, examples, and a quick check based on the caption context.
↻
Shared vocabulary with browsing
Words you save on YouTube sync to the same TalkClips account used by Vocabulary Mastery, so reading and watching feed one word list.
✦
Batch caption translation
Caption lines are translated in short batches so the sidebar stays readable without waiting on the whole video.
▣
Video word stats
See which words in the current video you already know, which are new, and which still need review — then jump into a review session.
How it works
Four steps from install to a word list you will actually review.
1
Install the extension
Add TalkClips Captions from the Chrome Web Store. Pin it if you want one-click access to sign-in and settings.
2
Open any YouTube video
The bilingual overlay and transcript sidebar appear on the watch page when captions are available.
3
Read, click, and save
Follow dual captions, click a line to seek, and click a word to open Word Coach. Saved words go to your shared vocabulary.
4
Review later
Open review from the sidebar, or continue the same words in Vocabulary Mastery while you read articles.
Who it is for
English learners on YouTube
Use videos you already watch — news, explainers, vlogs — instead of a separate course library.
Immersion learners
Keep native audio on, read a translation only when you need it, and mine sentences without leaving the player.
Students building a word list
Capture vocabulary from lectures and tutorials, then review with AI stories instead of copying into a spreadsheet.
Built for YouTube, not a clone of Netflix tools
TalkClips Captions is a YouTube-first Language Reactor alternative. It does not add dual subtitles to Netflix or Disney+. If your study time is mostly YouTube, that focus keeps the overlay fast and the transcript useful.
Word learning, not only hover-translate
Hover dictionaries are helpful. Word Coach goes further: it uses the caption line as context, saves the word to your account, and connects to review stories and sentence practice in Vocabulary Mastery.
One account across watching and reading
Most subtitle extensions stop at the video. TalkClips treats YouTube and the rest of the web as one study loop — captions for input, Vocabulary Mastery for lookup and review.
Use it with Vocabulary Mastery
Keep the same word list when you leave YouTube. Select words on articles, docs, and social posts, then review them with AI stories.
Frequently asked questions
Does TalkClips Captions work on Netflix?
No. It runs on YouTube watch pages. If you need dual subtitles on Netflix, Language Reactor, Trancy, or Sabi are better fits. Use TalkClips Captions when YouTube is your main input source.
Is TalkClips Captions a Language Reactor alternative?
Yes, for YouTube. You get bilingual captions, a transcript, word lookup, and a saved vocabulary list. You do not get Netflix support, PhrasePump, or Anki export.
Do I need captions on the video?
The extension reads YouTube caption tracks for the video you are watching. Auto-generated and uploaded tracks both work when YouTube exposes them. Videos with no captions cannot show a transcript.
Is it free?
You can install it for free. A free plan includes a limited number of videos with processed captions. Unlock more with a TalkClips membership, which is shared with Vocabulary Mastery and the TalkClips app.
Does it work on mobile?
TalkClips Captions is a Chrome extension for desktop YouTube. For speaking practice on a phone, use the TalkClips Android app.
Add TalkClips Captions to Chrome
Free to install. Works on YouTube in Chrome. Membership is shared with the rest of TalkClips.
