    About Harker

    Harker: Private voice-to-text for Mac

    Harker is a voice-to-text app for Mac that types speech into whatever app has the cursor. Transcription runs locally with a Whisper model, so audio stays on the device and dictation works offline. The free tier covers unlimited local dictation, and a Premium tier adds AI writing styles, formatting, grammar cleanup and translation.

    Key Features

    • Local transcription: Speech is processed on the Mac with Whisper models, and every model tier is included in the free plan.
    • Global shortcut: Cmd+Shift+Space opens Harker from any app, with a hold-to-listen option for push-to-talk dictation.
    • Auto-paste anywhere: Text appears in the active text field, from email and docs to Slack, code editors, terminals and AI prompts, with no copy and paste.
    • Offline and account-free: On the free tier no audio is sent to the cloud, dictation works without an internet connection and no account is needed.
    • Context and punctuation: Harker understands context and punctuation while the user speaks at a natural pace, and supports dictation in multiple languages.
    • Writing styles (Premium): Formal, Casual and Concise modes reshape rough dictation into the register the message needs.
    • Smart formatting (Premium): Output can be shaped as an email, bullet points or notes, with grammar and punctuation fixed.
    • Translation and custom instructions (Premium): Dictated text can be translated into any language, and custom instructions and context guide the AI pass.
    • Text-only cloud pass: With Premium, only the finished text goes to the cloud for cleanup, never the audio, and it is not stored or used for training.

    Use Cases

    • Developers: Speaking long prompts, specs and instructions for AI coding tools instead of typing them, without leaving the editor.
    • Writers: Drafting articles, notes and messages by talking through ideas, then using Premium styles to tidy the result.
    • Students: Capturing notes and essay drafts faster than typing.
    • Accessibility: Writing without touching the keyboard for people who find typing difficult.

    Pricing

    The free plan costs $0 and includes unlimited local transcription, all Whisper model tiers, the global shortcut, auto-paste and multi-language input. Premium starts at $5.75 per month on the annual plan and adds writing styles, formatting, grammar fixes, translation and custom instructions, with a 7-day free trial that needs no credit card. Harker requires macOS 12 or later, and a Windows version is listed as coming soon.

    Getting Started

    Harker suits Mac users who want free, on-device dictation in every app, with AI rewriting available as an optional paid layer.
