Every sentence of YouTube,
one click away.

A sentence-level transcript lives next to the player — free, no account needed. Click any line to jump there. Sign in only when you want an AI summary or the idioms and rare expressions natives glide past.

Who said transcripts have to be
coarse blocks of text?

YouTube's built-in transcript lumps lines together by caption cue, not by meaning. Transcript Jump splits the same caption stream on real sentence boundaries, so the next click always lands on a whole thought — not mid-phrase. It's the difference between skimming a textbook and skimming a table of contents.

Features

Everything you need.
Nothing you don't.

A thin panel that respects the video. Five tools stacked behind a single toggle, each one built for the way you actually watch.

Per-sentence transcript with each line timestamped
Free

Per-sentence jumping

Finer than YouTube's default transcript. Every sentence is its own clickable anchor. Click 2:23 and you're at the start of the thought, not four seconds before it. Free, no sign-in.

Bilingual mode showing English and Japanese side by side
Free*

Bilingual, side by side

Pick any two languages from the 99 YouTube supports. Both streams scroll in lockstep with the video, so you can read and listen without swapping tabs. *Free when YouTube already has captions for both languages. When it doesn't, we translate it for you with AI — those translations count toward your plan.

AI-generated summary in Japanese next to the video
Paid

AI summary

A single paragraph, a handful of key points, and a plain-English analogy — written in the transcript's own language. No more 40-minute intros to scrub past.

Expression notes inline with the transcript
Paid

Expressions helper

Idioms, slang and rare vocabulary — underlined under each sentence with a one-line gloss. Built for learners who are past the phrasebook stage.

Export dropdown showing txt and csv options
Free

Export anywhere

Copy plain text, or download .txt / .csv — with or without timestamps. Your notes, your notebook, your flashcard app.

Dark mode summary panel
Included

Dark mode, built in

Matches YouTube's own theme automatically. Nothing glows, nothing blinds. Two a.m. study sessions approve.

How it works

Three clicks to a
readable video.

  1. Install the extension

    One-click install from the Chrome Web Store. It takes about the length of a YouTube pre-roll ad.

  2. Open any YouTube video

    The sidebar appears on the right. If the video has captions — auto-generated count — you're set.

  3. Click the sentence you want

    The player jumps — no account, no setup. Toggle Bilingual, Summary or Expressions whenever you need more; AI features are free for your first three videos once you sign in.

FAQ

Questions we get often.

Which videos does it work on?

Any YouTube video that has captions — both creator-uploaded and auto-generated count. If YouTube can show a transcript for it, Transcript Jump can split that transcript sentence by sentence.

Do I need an account?

No — not for the transcript itself. Per-sentence jumping, coarse view, and export work without signing in. You only sign in with Google when you want an AI feature (Summary, Expressions, or translation) so we can track your trial credits and plan.

How does the AI summary work?

When you click Summarize, we send the transcript to a large language model on your behalf and return a short paragraph, a few emoji-led key points, a plain-language analogy, and a keyword glossary — in the transcript's own language. We don't retain the transcript text.

What's the difference between coarse and per-sentence view?

Coarse view groups lines in ~25-second / ~320-character chunks — roughly what YouTube's own transcript gives you. Per-sentence view splits the same audio into real sentences using language-aware parsing. Same video, one click of a toggle.

Can I cancel anytime?

Yes. Both Monthly and Yearly cancel from your subscription management screen with one click — no email, no retention call. You keep access until the period you've already paid for ends.

Do you store my transcripts or summaries?

Transcripts are passed to our AI provider only to generate Summary / Expressions output, and are not retained on our servers. We store your account email and user ID for billing, trial usage (feature × video ID × timestamp), and the subscription reference our payment provider gives us. That's it. See our privacy policy.
