The transcript, right beside the video

UpSolo puts the full transcript next to the YouTube player, synced as it plays, so you can follow it, search it and study from it without leaving the page.

Add to Chrome

FREE · NO ACCOUNT NEEDED TO READ

Free, no account needed

Read along with what you watch

Install it and open any video with captions. The panel sits in YouTube's right column, above the recommendations.

Follows the video

The line being spoken is highlighted as it plays. Click any timestamp to jump there.

Three ways to read

Lines, Paragraphs or Plain text, split by the video's chapters.

Search

Find a word and jump straight to the moment it's said.

About 150 languages

Switch caption tracks, or auto-translate and read the original under each line.

Copy or download

Take the text as .txt, .md, .srt, .vtt or .json.

Where you are

The chapter you're in shows at the bottom of the panel.

With a free UpSolo account

Study tools, in the same panel

Connect your account from the panel and the study tools join the transcript. Everything you save goes to your library, where the full workspace adds notes, highlights, quizzes, mind maps and more.

The extension's Summary tab: the video's main idea, then three key moments with their timestamps

A summary with key moments

The main idea, a short recap, then the moments that matter, each linked to its timestamp.

The extension's Tutor tab: a question about the video and an answer that cites the 0:27 moment

Ask the tutor

It knows the whole video. Answers point to the moments they come from, and a click takes you there.

A transcript line selected in the extension, with Quote and Card buttons above it

Any line as a quote or a card

Select the text and pick one. It lands in your UpSolo library, ready for spaced review.

The extension's transcript auto-translated into Vietnamese, with the playing line highlighted

Read it in your language

Auto-translate the transcript line by line, synced to the video like the original.

The summary and tutor use credits: free ones every day, no card required, a few of them usable right in the extension.

Fair questions

Is it free?

Yes. Reading, searching, translating and downloading transcripts are free and need no account. The summary and tutor use credits from your UpSolo account; you get free ones every day, no card required, and a few of them can be spent in the extension (the rest work on upsolo.me, and purchased credits work in both). Saving a line as a quote or a flashcard costs nothing.

Which videos does it work on?

YouTube videos with captions, auto-generated ones included. On a video with no captions at all, you can turn on live captions (Chrome transcribes the audio as it plays, free, nothing is sent to UpSolo) or, with an account, generate a transcript for credits.

What does it send to UpSolo?

Without an account, nothing: the captions go straight from YouTube to your browser. Once you connect, it tells UpSolo which video you open (to check your library), and saving a video sends its captions to keep in your library. No ads, no analytics, no tracking.

What about Edge, Firefox and Opera?

The Edge version is in review with Microsoft. Firefox and Opera come later.
