Offline Dictation for Mac
Three on-device transcription engines. No internet required. No data leaves your Mac. Whisperer is the most private dictation app available — and at $14.99 lifetime, the most affordable.
100% offline voice-to-text for macOS with Whisper (Metal GPU), Parakeet (Neural Engine), and Apple Speech. Code Mode for developers. Per-app profiles. Personal dictionary. No subscription.
Why Offline?
Cloud dictation sends your voice to remote servers. Whisperer keeps everything on your Mac — faster, cheaper, and completely private.
Complete Privacy
Your voice data never leaves your Mac. No cloud servers, no third-party processing, no data collection. What you say stays on your device.
Zero Latency
No network round-trip means instant results. Whisperer processes speech locally with ~300ms live preview — faster than any cloud service.
Works Anywhere
Airplane mode, coffee shop without WiFi, secure network — Whisperer works everywhere because it never needs the internet after the initial model download.
No API Keys or Accounts
No sign-up required. No API keys to manage. No cloud quotas or rate limits. Download, install, and start dictating immediately.
No Per-Minute Charges
Cloud dictation services charge per minute of audio. Whisperer is $14.99 once — dictate unlimited hours without worrying about costs.
Apple Silicon Optimized
Metal GPU acceleration for Whisper, Neural Engine for Parakeet. Whisperer is built specifically for Apple Silicon to maximize speed and efficiency.
Three Transcription Engines
Hot-swap between engines without restarting. Each optimized for different hardware and use cases.
Whisper
DefaultOpenAI's Whisper via whisper.cpp. Best accuracy and broadest language support. Uses Apple Silicon Metal GPU for fast inference.
Parakeet
FastestNVIDIA Parakeet via CoreML. Runs on the dedicated Neural Engine, leaving GPU free. Supports CTC vocabulary boosting from your dictionary.
Apple Speech
NativeApple's SpeechAnalyzer framework. Zero setup, no model downloads. Best for quick dictation when you don't need maximum accuracy.

Frequently Asked Questions
Is Whisperer really 100% offline?
Yes. After the initial model download (75MB–2.9GB depending on model), Whisperer never contacts any server. All transcription, AI post-processing, and text insertion happen entirely on your Mac.
What is the best offline dictation app for Mac?
Whisperer is the most feature-rich offline dictation app for Mac, with three transcription engines (Whisper, Parakeet, Apple Speech), Code Mode for developers, per-app profiles, and personal dictionary — all for $14.99 lifetime. No competitor offers this combination at any price.
How does offline dictation compare to cloud-based?
Offline dictation is faster (no network latency), more private (no data leaves your device), and cheaper (no per-minute charges). Cloud-based services may have slightly higher accuracy for niche languages, but for English and major languages, local Whisper models match or exceed cloud quality.
Does offline dictation work on Intel Macs?
Yes, but Apple Silicon is recommended. Whisper runs on CPU for Intel Macs (slower). Parakeet and Apple Speech require Apple Silicon. Most models work well on M1 and later.
How much storage do the models require?
Whisper models range from 75MB (Tiny) to 2.9GB (Large V3). The recommended balanced model is about 500MB. Parakeet models are 100–200MB. You choose which models to download.
Can I use offline dictation in any app?
Yes. Whisperer inserts text into any focused field on your Mac — VS Code, Cursor, Slack, Gmail, Notion, Terminal, and any other app. It uses Accessibility insertion with a paste fallback.
Is there a free offline dictation app for Mac?
Apple Dictation is free and runs on-device on Apple Silicon Macs. However, it lacks Code Mode, per-app profiles, personal dictionary, and file transcription. Whisperer's base app is $2.99 — essentially free compared to $99–$249 competitors.
Does Whisperer support multiple languages offline?
Yes. Whisper supports 99+ languages offline. Parakeet supports 25 languages. You can set different languages per app with per-app profiles and use AI translation between languages — all offline.
