Secret Mode
Introducing Secret Mode, a new feature in Nikke. When transcribing sensitive audio data, many users worry about their data being stored on servers. Secret Mode is our answer to those concerns.
In Secret Mode, audio files and transcription results are never stored on our servers. All processing happens in your browser, and everything is completely erased when you close the browser. Perfect for medical consultations, legal discussions, HR interviews, and other sensitive audio.
Using it is simple. Just click the Secret Mode icon in the top right corner to switch to a dark-themed private workspace. Drop your audio file just like normal mode, and download results in txt, srt, or csv format.
Secret Mode is available for Basic plan subscribers and above. Use it whenever privacy is your top priority.
