Does it work with every app?
CapCrush listens to the sound of the app you’re watching through the iOS screen broadcast. Some apps restrict capture or protect their content, so CapCrush may not work with every app or video.
Does it read the translation out loud?
No. The iPhone app shows captions only. For interpreter voice, use BizCrush Live in Chrome or Edge on a computer.
Is it free?
The app is free to download. Try it for 5 minutes in total without logging in, then continue with your BizCrush account — the free plan included.
Which languages are supported?
Choose from 60 caption languages. The app menu is in English and Korean.
How fast are the captions?
Sentences update as they are spoken. Translations may be delayed or contain errors, and Easy Read mode can appear later than the video.
What happens to the audio?
Audio from your video app is sent to our server for recognition and translation, and the recognized and translated sentences are stored on the server. You can end captions and capture any time.
How do I delete my account?
You can request deletion of your account and data on our account deletion page, without logging in.
