Why this fits

Halopen, paired with Bolt.

Halopen is a native macOS dictation app that lands voice-typed app briefs at the cursor in Bolt — StackBlitz's AI app builder running at bolt.new in Safari, Chrome, Arc, Firefox, or Brave. Hold the function key, speak the full app brief (data model, user flows, design language, integrations), release; the verbatim description appears in the Bolt prompt input through the macOS Accessibility API on Apple Silicon and Intel.

Bolt is StackBlitz's AI app builder. You describe the app you want — the data model, the user flows, the design language, the integrations — and Bolt scaffolds, builds, and previews it in seconds. The constraint that bounds Bolt's output is the same constraint that bounds every AI app generator: the description.

Halopen is the Mac voice layer for that description. Hold the function key in the Bolt prompt input, talk through the full app brief, release. The complete description lands at the cursor verbatim. Compare the reviewed draft with your usual typing workflow.

Mac users running Bolt with voice typing tend to ship more variant apps. The marginal cost of "let me try a different version of this idea" drops to near zero, because the brief is the work and the brief is voice-cheap.

About Bolt

What is Bolt?

Bolt is the in-browser AI app builder from StackBlitz. It generates full-stack applications from natural-language descriptions, runs them in WebContainer, and lets developers iterate on the result by chat — all without local environment setup.

The workflow

How to use Halopen with Bolt.

  1. 1

    Open Bolt in your browser

    Try a short, harmless draft in the exact Bolt field you use. Halopen is designed for standard Mac text fields; permissions, focus, Secure Input and custom widgets can affect insertion. Confirm that the text arrived and review it before submitting.

  2. 2

    Click into the prompt input

    The cursor sits in the field where the full app description goes.

  3. 3

    Hold the function key — describe the app fully

    "Build a habit-tracking app. Each user has up to twelve habits. Each habit has a name, an icon from a fixed set, a target frequency (daily, three-times-a-week, weekly), and a streak count. The home screen shows today's habits as cards; tapping a card marks it done for today. The history screen shows a calendar grid for each habit with check-marks on completed days. Use TailwindCSS, calm editorial register, no neon. Mobile-first responsive."

  4. 4

    Submit the brief; review the generated app

    The full description lands at the cursor verbatim. Submit. Bolt generates the app; you preview it in the WebContainer; you iterate.

  5. 5

    Iterate by voice

    The next prompt — feature add, design tweak, edge-case fix — comes the same way. The iteration loop runs at thinking speed because the prompt-construction cost dropped.

What matters for Bolt

The Halopen features that earn their place.

  • Verbatim — your product vision survives

    For Bolt, Verbatim is the default output mode, with optional cleanup available. Recognition can still mishear a word or omit a detail. Review the completed draft for names, wording and constraints before using it.

  • Long-form holds — for the multi-paragraph brief

    A full app description ships in one hold. The live preview shows the partial transcript as you speak.

  • Evaluate your intended Mac app and input field

    Try a short, harmless draft in the exact Bolt field you use. Halopen is designed for standard Mac text fields; permissions, focus, Secure Input and custom widgets can affect insertion. Confirm that the text arrived and review it before submitting.

  • Live preview catches misreads

    For Bolt, check names, identifiers and punctuation against your intended draft. Optional live partials are provisional and may differ from the final transcript; repeating a term does not guarantee replacement. Type or paste exact strings when needed.

  • Native Mac app

    Halopen is a native Mac app. Resource use depends on your hardware, recognition mode, model and other apps. Test a representative session before relying on it alongside your usual software.

  • Free for 14 days, no credit card

    Use the 14-day trial to evaluate a representative draft, including correction and review. Pro is $19/mo or $179/yr; Lifetime is $499 once.

Try it yourself

A typical Bolt app brief dictated into the prompt input:

Example to read aloud — not a recorded result

“"Build a reading-list app for people who save articles to read later. The core entity is a saved article — URL, title (auto-fetched from the URL's page title), author, estimated reading time in minutes, optional cover image URL, status (unread, reading, read, archived), tags (free-form, comma-separated), date saved, optional date read. The home view defaults to the unread list, sorted newest-first. There's a saved-search bar that filters by tag, text search across title and author, and status. Users can mark articles as read with one tap; archived articles disappear from the home view but remain searchable. Use TailwindCSS for styling, editorial register — cream paper, warm graphite text, magenta accent on links and tag pills. Source Serif 4 for headlines, Inter for body text. Mobile-first responsive layout. Light mode only for the first version."”

  • · Illustrative practice text, not a recorded Halopen result.
  • · Read a short section aloud, then check the inserted draft for errors.
  • · Keep exact names, numbers and formatting under your own review.

Why Halopen

The dictation tool that earns its place.

AI app generators reward thorough briefs. The difference between a Bolt-generated app that ships at MVP quality and one that ships at portfolio quality is description specificity — every product detail, every design preference, every "don't do this" the developer wanted honored.

Halopen is the calmest Mac voice layer for those briefs. Verbatim by default; long-form holds for multi-paragraph specs; system-wide so the same hotkey covers Bolt and every adjacent surface — the marketing site you'll write next, the Stripe Dashboard you'll wire up, the launch tweet you'll post.

For Mac users running Bolt, voice typing is the fastest path from "I know the app I want" to "Bolt has the full spec."
