Captionshaper runs on your computer. Your videos, audio and captions never leave it.
What the app does with your files
Captionshaper reads the video or audio you open, recognises the speech and writes captions, all on your computer. It saves your edits in its own folder so you can come back to them. Nothing is sent anywhere.
Network requests
The app makes one kind of request: downloading a speech model from Hugging Face (huggingface.co) when you click Download. That request contains nothing about your files. After that, Captionshaper works with the internet off.
Accounts, analytics and tracking
There are none, in the app or on this website.
