Why this fits

Halopen, paired with Aider.

Try a short, harmless draft in the exact Aider 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.

Aider runs in your terminal and edits your codebase by AI. You give it a natural-language instruction; Aider proposes edits, applies them, and commits. The entire loop is text in, text out — and the more precise your instructions, the better Aider performs.

Halopen is the dictation tool built for this loop. Hold the function key, speak the instruction the way you’d say it to a co-worker, release. The text lands in the Aider prompt input verbatim. Aider acts. You review the diff. You speak the next instruction.

About Aider

What is Aider?

Aider is an open-source AI pair programming CLI by Paul Gauthier. It works with GPT, Claude, and many open models, runs in any Mac terminal, and supports Python, JavaScript, TypeScript, Swift, Go, Rust, and most other major languages.

The workflow

How to use Halopen with Aider.

  1. 1

    Run Aider in your terminal

    `aider` opens a session bound to your repo. The prompt input is a standard terminal text field.

  2. 2

    Hold the function key on Halopen

    Recording indicator appears.

  3. 3

    Speak your instruction

    "In auth-handler-dot-ts, replace the JWT-decode logic with the verifyToken helper from auth-utils. Update the error handling to throw an UnauthorizedError instead of returning null."

  4. 4

    Release

    Text lands in the Aider input. Hit return. Aider proposes the edit; you accept or refine.

  5. 5

    Iterate by voice

    Refinements, file additions, scope adjustments — all dictated.

What matters for Aider

The Halopen features that earn their place.

  • Test your Aider input field

    iTerm2, Apple Terminal, Warp, Ghostty, Alacritty, kitty — Halopen runs system-wide.

  • Verbatim technical prompts

    File names with hyphens and dots, helper-function names, error-class names — captured as spoken.

  • Live preview for symbols

    For Aider, 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.

  • Idles light

    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.

  • Privacy by default

    Halopen sends audio to a transcription service only while you hold the key. Your code stays where you keep it.

  • Free for 14 days

    Hundreds of Aider instructions per month free; Pro $19/mo for unlimited.

Try it yourself

Aider instruction dictated for a multi-file refactor:

Example to read aloud — not a recorded result

“"Add aider-files for src-api-routes-orders-dot-py and src-models-order-dot-py. Then refactor the create-order endpoint so all the validation runs through pydantic instead of the manual asserts. Keep the response shape unchanged. Don’t touch the get-order endpoint."”

  • · 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.
