Questions about Online Tuner

Is a Vidgo account required?

You can start these utilities without signing in, and they do not consume generation credits.

Are all input modes processed locally?

Calculations and most editing controls run in the page. Browser speech recognition and some spoken voices may use your browser provider’s service; file-based Whisper transcription runs locally.

Do I have to install an app?

No desktop installation is needed. A feature may fetch its processing library or model the first time you use it.

Can I work from a phone?

A current mobile browser supports many of these tasks. Keyboard, mouse, screen-capture and larger-model workflows depend on device support and are often easier on a computer.
