Overview
MacWhisper addresses the critical privacy concerns of transcribing sensitive meetings, client interviews, and lectures without transmitting private audio to third-party cloud servers. By executing speech-to-text models directly on Apple Silicon processors and local Neural Engines, the utility guarantees that audio files and transcripts remain stored exclusively on the user's personal hardware.
The application accepts drag-and-drop media imports across common audio and video formats, and can record directly from system microphones or internal computer audio during video conferencing sessions. An integrated transcript reader syncs recorded speech with generated text blocks, allowing users to scrub through timestamps, inspect playback segments, and correct typos or punctuation intuitively.
For power users, MacWhisper expands into automated processing pipelines. It features speaker diarization to separate conversation turns between distinct voices, watch folder monitoring for automatic background transcription, and flexible export formats suitable for subtitles and text editing.
Features and functionality
- Local on-device transcription: Executes speech recognition models offline on macOS hardware without sending audio data across the network.
- Multiple Whisper model weights: Accommodates lightweight models such as Tiny and Base alongside high-accuracy options including Medium and Large.
- Speaker diarization: Automatically distinguishes between different speakers throughout multi-voice discussions.
- System and microphone recording: Captures internal Mac system audio alongside active microphone feeds during video meetings.
- Comprehensive subtitle and document exports: Generates SRT, VTT, PDF, DOCX, CSV, and plain text files with precise timestamp alignment.
Use cases
- Journalistic and confidential interviews: Transcribe long audio recordings while maintaining strict source protection and data confidentiality.

Required experience level
MacWhisper is straightforward for beginners immediately following installation, requiring only a simple drag-and-drop action to yield complete transcripts. Advanced practitioners can explore technical configurations, such as custom prompt vocabularies, private external API keys for post-processing summaries, and automated directory monitoring.
Integrations
The software is engineered exclusively for Apple computers running macOS. It integrates with macOS productivity workflows through watch folders, system audio capture extensions, and native keyboard shortcuts. Users can optionally connect third-party AI API keys to generate automated meeting summaries and formatting enhancements.
Plans and access
MacWhisper operates under a freemium model. The permanent free edition allows unlimited local transcriptions using smaller speech models such as Tiny and Base. The Pro edition is available as a one-time lifetime license purchase via Gumroad, unlocking larger model weights, speaker diarization, and batch transcription. On the Mac App Store, the app is offered as Whisper Transcription with subscription and in-app purchase alternatives.
Because the tool executes machine learning models offline on local hardware, it provides a dependable privacy profile with zero cloud data retention requirements.
