Superwhisper: Offline AI Voice-to-Text Dictation for Mac (2026)

What Is Superwhisper? A Complete Overview (2026)

Superwhisper is an AI-powered voice-to-text dictation application designed for macOS (13 and later) and iOS. Built on the whisper.cpp framework -- an optimized C++ implementation of OpenAI's open-source Whisper speech recognition model -- Superwhisper runs transcription entirely on your device without sending audio data to external servers. This local-first architecture ensures both privacy and offline functionality.

The app works system-wide, meaning you can dictate text into any application on your Mac: Slack, Gmail, VS Code, Notion, Pages, or any other text field. Simply press the default keyboard shortcut (Option + Space) and start speaking. Superwhisper transcribes your speech in real time and pastes the result directly into the active text field.

Core Features

• Offline Processing -- All transcription runs locally using Apple Silicon or Intel hardware. No internet connection is required, and no audio leaves your device.
• Multiple AI Models -- Choose from Nano (fastest, smallest), Fast, Standard, Pro, and Ultra models. Larger models deliver higher accuracy at the cost of more processing power.
• 100+ Languages -- Superwhisper supports over 100 languages and dialects out of the box, powered by Whisper's multilingual training data.
• Custom Modes -- Create personalized dictation modes with specific AI instructions for formatting, summarization, or writing style adjustments.
• BYO API Keys (v2.0) -- Bring your own API keys from OpenAI, Anthropic, Deepgram, or Groq to access cloud-based AI models for enhanced text processing.
• File Transcription -- Upload audio and video files to generate accurate transcripts, in addition to live dictation.

Since its launch on Product Hunt and Hacker News, Superwhisper has gained a dedicated following among developers, writers, and professionals who need fast, private dictation. The version 2.0 update introduced bring-your-own API key support, expanding the app beyond purely local processing into a hybrid local-cloud architecture.

Best Superwhisper Alternatives in 2026

While Superwhisper excels at offline, privacy-focused dictation on Mac, several competing apps offer different strengths. Here are the top alternatives based on features, pricing, and platform support:

Superwhisper Pricing Breakdown (2026)

Superwhisper uses a freemium model with a permanent free tier and three paid options. All paid plans unlock the same Pro features -- the difference is billing frequency. One license covers both Mac and iOS devices. Students can get 40% off through Student App Centre.

Does Superwhisper Have a Free Version?

Yes. Superwhisper offers a permanent free tier that remains available indefinitely after installation. The free version includes unlimited access to three AI voice models (Nano, Fast, and Standard), the ability to create up to 3 custom dictation modes, and 25 AI text-processing prompts per day. These smaller models provide good accuracy for everyday dictation tasks.

New users also receive 15 minutes of complimentary access to Pro features, including the larger Pro and Ultra AI models. This trial period lets you experience the enhanced accuracy of larger models before deciding whether to upgrade. After the 15-minute trial expires, all free tier features continue working without restriction.

What the Free Version Cannot Do

• No Pro or Ultra model access -- The most accurate transcription models require a paid subscription
• Limited to 3 custom modes -- Pro users get unlimited custom modes with personalized AI instructions
• 25 prompts/day cap -- AI text reformatting and processing prompts are limited on the free tier

How to Use Superwhisper: Beginner's Guide

Getting started with Superwhisper takes about five minutes. Here is a step-by-step walkthrough for new users on macOS.

Step 1: Install Superwhisper

Download Superwhisper from the Mac App Store (search for "Superwhisper" or use App ID 6471464415). Alternatively, install via Homebrew by running brew install --cask superwhisper in Terminal. The app requires macOS 13 Ventura or later and works on both Apple Silicon and Intel Macs.

Step 2: Grant Permissions and Download a Model

On first launch, Superwhisper's onboarding wizard guides you through essential setup: granting Accessibility permission (required for pasting text into other apps), granting Microphone permission (required for recording your voice), and selecting an audio input device. You will also download your first AI model -- the Nano or Fast model is recommended for quick setup, as larger models require more disk space and RAM.

Step 3: Start Dictating

Open any app where you want to type -- a browser, email client, code editor, or notes app. Press Option + Space (the default keyboard shortcut, which is customizable). A small waveform indicator appears, showing that Superwhisper is listening. Speak naturally, and when you stop or press the shortcut again, the transcribed text is automatically inserted into the active text field.

Step 4: Customize Your Modes

Click the Superwhisper icon in the macOS menu bar to access settings. Create custom modes that define how your dictation is processed -- for example, a "Clean Prose" mode that removes filler words and formats paragraphs, or a "Code Comments" mode optimized for technical vocabulary. Each mode can include specific AI instructions for text transformation.

Best AI Dictation and Audio Tools in 2026

The AI dictation and speech-to-text landscape in 2026 offers specialized tools for different workflows. Here are the standout platforms across dictation, transcription, and audio/video editing:

• Superwhisper -- Best for privacy-focused, offline dictation on Mac using local Whisper models. Supports 100+ languages with Pro/Ultra models for maximum accuracy.
• Wispr Flow -- Best cross-platform dictation tool with generous free tier (2,000 words/week) and availability on Mac, Windows, and iOS.
• MacWhisper -- Best for batch transcription of recorded audio and video files. Clean, focused interface with local Whisper processing.
• Aqua Voice -- Best for long-form writers who want polished, publication-ready text from dictation with real-time visual feedback.
• NemoVideo -- AI-powered agentic video editing with built-in smart captions, audio editing, and chat-based workflow. Ideal for content creators who need both audio and video capabilities.
• OpenWhispr -- Best free, open-source option for cross-platform dictation on Windows, Mac, and Linux with hybrid processing.

Does Superwhisper Have an API?

Superwhisper does not offer a public REST API or SDK for third-party developers to integrate its dictation capabilities into external applications. It is designed as a standalone desktop and mobile app, not as a platform or service with programmatic access.

However, Superwhisper version 2.0 introduced a "Bring Your Own API Key" feature that allows users to connect their own API keys from AI providers such as OpenAI, Anthropic, Deepgram, and Groq. This enables access to cloud-based language models within the Superwhisper interface for enhanced text processing, reformatting, and summarization tasks beyond what local models can do.

Developer Integrations

For developers looking to use Superwhisper in their workflow, an Alfred workflow (alfred-superwhisper) is available on GitHub for automating Superwhisper controls via Alfred on macOS. Superwhisper also pairs well with AI coding tools like Cursor AI, enabling hands-free coding where you dictate instructions that the AI assistant translates into code.
