PROTOCOL // QUICK START
Operational in three steps
Open a video
Open any YouTube video that has captions — manual or auto-generated.
Turn subtitles on
Hit the CC button once. Xtrakt intercepts the caption stream the moment YouTube fetches it — no extra network calls, no API keys.
Search, jump, export
Type to filter the transcript live, click a result or a glowing tick on the progress bar, export as .txt, or hit Read.
FIELD DEMO // 01
The whole transcript, one click.
Download the complete transcript as a .txt file — plain prose or [MM:SS]-timestamped — or copy it all to the clipboard. Yours to keep, quote, or feed to an LLM.

FIELD DEMO // 02
Every word, indexed.
Search inside any YouTube transcript, jump to the exact moment, export it, or read along in an immersive full-screen reader.
The full transcript is captured in the background and filtered live as you type. Every hit becomes a glowing tick on YouTube's native progress bar — click to seek.

FIELD DEMO // 03
Density, measured.
Xtrakt rates the lexical density of every transcript and recommends a playback speed. Dense lecture? Slow down. Light vlog? Speed up.
Search hits on the progress bar
FIELD DEMO // 04
Read along, word by word.
The immersive reader lights up each word in sync with the audio, karaoke-style. Click any word to seek. Scroll freely — auto-follow pauses, then resumes.
