The best ideas don’t always arrive

Ready when the thought arrivesfn + shift

Keep your thinking
to yourself.

Local speech recognition gives your words a shorter journey: from your voice to a model on your Mac.

Your audio. On your device.

Use Whisper or Moonshine for local inference. Once the engine and model are installed, local transcription runs on your Mac.

A model that suits your words.

Choose multilingual Whisper models, including an option for Intel Macs. Moonshine for English requires Apple silicon, macOS 15+, Python 3.8+ and ffmpeg. Configure recognition and optional writing cleanup separately.

Room for your vocabulary.

Add the names, phrases and specialist terms you use. Review corrections and keep a transcript history for recovery.

Local processing depends on your chosen engine and settings. Optional cloud providers receive the data required for their requests and may charge separately.

From a thought
to a first draft.

One Line for Mac

$19USD / once

  • Local Whisper and Moonshine speech options
  • Your vocabulary, corrections and history
  • Future app updates included in the offer
  • No recurring app subscription

Early access. Manual installation required. This app is not Apple-notarized. macOS may block it, and updates may require renewed approval and permissions. Local engines and models require separate setup. Read requirements and install instructions before buying.

No refunds, except where required by law. Sold by Sicapo. $19 USD one time.

A few straight answers.

Is it free forever?

One Line costs $19 once. There is no recurring app subscription. Future app updates are part of the offer. Optional external services can have their own charges.

Does my audio leave my Mac?

Not when you select and use a local engine for local inference. If you enable a remote transcription or cleanup provider, the data needed for that step goes to that provider. A local server address alone does not prove local processing.

Can I download it today?

The early-access installer is available after payment. It is not Developer ID signed or Apple-notarized. Read the manual installation guide before purchasing; managed Macs may prohibit installation.

Which Macs and apps will it support?

The package contains Apple silicon and Intel binaries with a macOS 12 deployment target. Older macOS versions and physical Intel Macs have not completed compatibility validation. Engine requirements differ; Moonshine needs Apple silicon and macOS 15+. Text insertion depends on the app, field and permissions.

How do updates work?

Future app updates are included. Download updates manually using your purchase confirmation page. Automatic in-app updates are not implemented. A new build may require macOS approval and permissions again.

Who handles my payment?

Stripe processes the one-time payment for One Line. Sicapo is the legal merchant. No refunds are offered, except where required by law.

An early start. Your own words.

One Line 0.1.22 is available as manual-install early access. Read the installation requirements and limitations before deciding whether it fits your Mac.
