Common questions.
Live transcripts, real-time search, which sites are supported, and when you need the Chrome extension.
What is LiveScript?
LiveScript is a web app and Chrome extension that turns live audio into a real-time, searchable transcript. Paste a YouTube or Twitch URL in the web app, or install the extension to transcribe any other site that plays audio - sports streams, news, webinars, conference calls. Within seconds every spoken word is searchable in your browser.
How do I get live YouTube transcriptions?
Open LiveScript, paste a YouTube live or VOD URL, and we transcribe the audio in real time. You get a live transcript you can search and skim - like live YouTube captions, but built for full-text search, keyword alerts, and anyone who needs to find a specific spoken word the moment it's said.
How does LiveScript work?
LiveScript listens to the audio of a YouTube live stream, transcribes it as it plays, and streams the text into your browser within seconds. Every word is searchable the moment it is spoken.
Is LiveScript just a YouTube caption scraper?
No. For live streams, LiveScript transcribes the audio in real time as it airs and pushes new lines to your browser within seconds - you do not have to wait for the broadcast to end. That is different from link-pasting tools that only pull YouTube's finished caption file after a stream is over. LiveScript also supports finished videos: we can fetch existing YouTube captions or generate a full transcript from the audio, but the core live product is real-time speech-to-text while the stream is still running.
Are YouTube auto-captions the same as LiveScript?
YouTube's on-screen captions are great for accessibility; LiveScript focuses on a fast, searchable transcript with timestamps and keyword alerts - built for people who need to find words the moment they are spoken.
Is LiveScript free?
LiveScript has a free plan with a 5-minute transcript delay and 30-minute history. Pro ($19.99/month) unlocks real-time transcripts, unlimited streams, and keyword alerts with sound. A $4.99 Day Pass gives full Pro access for 24 hours.
Which YouTube live streams does LiveScript support?
LiveScript supports any publicly accessible YouTube live stream. Paste the full youtube.com/watch, youtu.be, or youtube.com/live URL and LiveScript begins transcribing immediately.
Does LiveScript work with Twitch live streams?
Yes - paste any twitch.tv/<channel> URL and LiveScript transcribes the live audio in real time, the same way it does for YouTube. YouTube remains our primary focus, but Twitch live channels are fully supported.
Can LiveScript transcribe sites other than YouTube and Twitch?
Yes. YouTube and Twitch work straight from the web app - just paste a URL. For any other site that plays audio - sports streams, news sites, webinars, conference calls, Kick, and more - install the free LiveScript Chrome extension. It captures the audio playing in your browser tab and transcribes it in real time, so you can search the full transcript and set keyword alerts even on sites we can't reach from a URL alone.
Why do I need the Chrome extension for some sites?
For YouTube and Twitch we can fetch the stream's audio from its URL, so the web app works on its own. Most other sites don't expose their audio that way. The Chrome extension solves this by capturing the audio already playing in your tab - no URL required - which is why it's needed to transcribe arbitrary sites. The extension is free and your Pro features carry over automatically.
How fast is the real-time transcription?
Pro users receive transcripts with effectively zero delay - words appear in the browser within 1-2 seconds of being spoken. Free users see a 5-minute delay to encourage upgrading.
Can I set alerts for specific keywords?
Yes. You can tag any phrase and LiveScript will highlight it in the live transcript. Pro users can also enable an audio alert (beep) that fires the instant the tagged word is detected. Multiple tags are supported per stream.
Can I get notified when a YouTube channel goes live?
Yes. Pro users can add channel drop alerts: paste a YouTube channel URL or @handle and LiveScript emails you the moment that channel posts a new video or starts a live stream - usually within a minute, and more reliably than YouTube's own bell notifications. You can also have it auto-start a real-time transcript so it's already building when you open the email.
Who is LiveScript built for?
Anyone who needs to find a specific phrase spoken on a live stream the instant it's said: journalists monitoring press conferences, researchers tracking live events, investors following earnings calls, compliance teams watching partner broadcasts, and other professionals who can't afford to scrub through hours of video. Some users also rely on it for prediction-market and trading research where information speed matters.
Can I upload my own audio or video file to transcribe?
Yes. Upload an audio or video file (mp4, mov, mkv, mp3, m4a, wav, and more) and LiveScript returns a fully searchable, timestamped transcript with an audio player you can scrub by clicking any line. Upload transcription draws from the same monthly minute pool as the live API - around 1,000 minutes on the Day Pass and 10,000 minutes on Pro, with top-up packs available. Free accounts get a starter pool of minutes to try it, with files up to 200 MB (5 GB on paid plans).
