Common questions

Does it work with headphones? +
Yes. LiveLingo captures audio from the browser tab itself, not from your microphone or speakers. It works the same whether you use headphones or not.
Does it work on Netflix? +
Yes. LiveLingo works on Netflix, YouTube, Disney+, Prime Video, Twitch, university portals, and any other site that plays video in Chrome.
How accurate are the subtitles? +
Very accurate for clear speech. Heavy background music or strong accents may reduce accuracy slightly, but it handles fast speech and natural conversation very well.
How much is free? +
Without an account you get 30 minutes per day, free. Create a free LiveLingo account and that doubles to 60 minutes per day. Your daily allowance resets every night at midnight.
Does LiveLingo store what I'm watching? +
No. Audio is processed in real time and never stored anywhere. We don't record what you watch, what is said, or any audio from your device.
Why do I need to refresh the page after installing? +
When you first install LiveLingo, it needs to load into any browser tabs that were already open. Refreshing the tab once lets it load in. After that you never need to do it again for that site.
Is the access key really free? +
Yes. The key gives you access to a free tier that is more than enough for everyday use. No credit card is required to create an account or generate a key.
