Does it save my data?

No. Inputs are processed in your browser and never uploaded to a server.

Can I use it on mobile?

Yes. The interface is fully responsive and works on iOS and Android.

What if my episode is over 25 MB?

OpenAI's API limit is 25 MB. Compress to a lower bitrate (e.g. 64 kbps mono MP3) or split the episode into chunks first.
