Mac
MurmurAI brings state-of-the-art speech-to-text transcription to macOS. Built for professionals, creators, and privacy-conscious users, MurmurAI runs 100% locally on your Mac using powerful speech engines — including WhisperKit, Parakeet, and Apple Speech — so your audio never leaves your device.
Choose your engine and workflow:
Multiple AI engines - optimized for speed, accuracy, and language support.
Multiple models - from tiny to large models for WhisperKit
File transcription - drop audio/video files and get fast, accurate text.
Speaker identification - automatically detect who’s speaking.
Refine diarization - name speakers, assign segments, merge and split as required
AI refinement - clean, formatted transcripts ready for export.
Export to TXT, SRT, VTT for editing or subtitles.
Privacy & Local-First Design
MurmurAI transcribes directly on your device. Your audio stays on your Mac and is never uploaded for processing. Optional AI refinement features may require internet access if external services are used.
Whether you’re dictating, transcribing interviews, or preparing subtitles, MurmurAI delivers fast, reliable results while keeping your data private and secure.
