No. SoundProof Legal runs 100% offline. All transcription, speaker identification, and OCR processing happens locally on your Mac's Neural Engine.
SoundProof Legal supports common formats including MP3, M4A, WAV, MP4, MOV, and most other formats that macOS can play natively.
Transcription accuracy depends on audio quality. For clear recordings, expect 90-95% accuracy. SoundProof generates rough draft transcripts intended for review and editing.
