Frequently Asked Questions
How do I know the file is not uploaded?
You can open browser developer tools and watch the Network tab while transcribing. The media file is not posted to SuperTextHub.
Are model files downloaded?
Yes. The browser downloads model files needed for local AI inference, then caches them.
Can I use this for sensitive work?
The local processing design helps reduce exposure, but you should still follow your professional compliance rules.
