Frequently Asked Questions
Is my audio data private?
Yes! All processing happens locally in your browser. Your audio files are never uploaded to any server. We cannot see or access your data.
How large can audio files be?
There's no hard limit since processing is local. However, very long files (over 30 minutes) may take longer to process depending on your device.
What audio formats are supported?
WAV, MP3, M4A, FLAC, OGG, WebM, and most common audio formats. The audio is decoded by your browser before processing.
Why is the first use slower?
The Whisper AI model (~150 MB) needs to download once. After that, it's cached in your browser for instant re-use, even offline.
