1. Define what “one-time purchase” must include
A one-time license means the core product does not require a recurring subscription under the offer reviewed here. It does not automatically promise every future major version, unlimited devices, permanent cloud services, or support for a Mac you buy later.
Write down the job before comparing prices: live text at the cursor, long-form push-to-talk, multiple languages, file transcription, custom vocabulary, local rewriting, optional cloud models, or a developer-specific output. Paying once for the wrong workflow is still wasted money.
- License scope: one Mac, several Macs, family sharing, or a named person.
- Update scope: current major version, lifetime updates, or unspecified.
- Service scope: local core features versus metered or bring-your-own cloud features.
- Artifact: live dictated text versus saved audio, meetings, files, or notes.
2. Test Apple Dictation before buying another app
Apple Dictation is included with supported versions of macOS and remains the correct first test for ordinary voice typing. Turn it on under System Settings → Keyboard, inspect the processing disclosure for the active language and configuration, and dictate the same passage in the field you actually use.
Before paying, also test Google AI Edge Eloquent if your missing capability is a no-subscription dedicated Mac app, Voice Edit, or local audio and video file transcription. Google’s reviewed Mac sources position it as no-cap and without a subscription, but still English-only on the current FAQ and without a published permanent Mac price.
Buy another app only after naming the missing capability. Common gaps include a different local model, a held-key or toggle workflow, broader language coverage, custom vocabulary, file transcription, persistent history, local cleanup, or a structured developer brief.
3. Compare the current pay-once shortlist
The reviewed first-party pages publish seven distinct one-time offers. Voice Type lists a US $19.99 lifetime unlock after a seven-day trial. Whryte lists US $24.99 once with local Parakeet processing, a three-day trial, file transcription, and diarization. VoiceInk lists lifetime plans from US $25 for one Mac to US $49 for three Macs and also publishes its source code.
TypeVox lists a permanently capped free tier and a US $39 Pro Lifetime license for two devices. Sotto lists US $49 once for three Macs, local models, file transcription, and optional OpenAI or Groq transcription with the user’s own key. Susurr lists €19.99 once for three active Macs and focuses on local WhisperKit dictation and robust insertion. IraVoice lists IraVoice Local at US $79 once for one computer, US $109 for two, or US $149 for three after a 3-day free trial, with an optional IraVoice Cloud subscription coming soon (not yet on sale); it focuses on on-device Parakeet dictation that spells code names in terminals and coding agents.
Currencies, taxes, launch discounts, refunds, device allowances, and update promises differ. Follow the current vendor page before purchasing; this dated guide is not a price guarantee.
4. Choose the speech path before the price
A local default can reduce recurring infrastructure cost and keep core speech recognition available after model setup. It can still require network access for the installer, model download, license delivery, updates, receipt verification, or an optional provider.
Voice Type, Whryte, TypeVox, VoiceInk, Susurr, Sotto, and IraVoice all document local speech paths for the configurations described in their current sources. Voice Type exposes optional rewrite tools; VoiceInk can use configured cloud providers; Sotto offers optional OpenAI and Groq transcription. IraVoice Local keeps speech recognition on the computer; the optional IraVoice Cloud subscription, coming soon, will send audio and text to IraVoice Cloud for recognition and polish, where IraVoice’s servers never store them, Groq does not retain them, Anthropic deletes API inputs and outputs within 30 days, and neither trains on them.
Do not transfer a local claim from one mode to every feature. Check the selected model, cleanup path, history, sync, destination app, and any provider key before sensitive use.
5. Compare total cost without pretending the future is known
For a pay-once app, the known starting cost is the purchase price plus any tax and optional provider usage. For a subscription, multiply the current monthly or annual price by the period you expect to use it, then add usage charges. Keep those calculations separate from feature value.
Do not assume a one-time vendor will operate forever or that a subscription will never change price. Download availability, macOS compatibility, model support, code signing, updates, and vendor continuity matter more than a simplistic three-year bar chart.
The strongest purchase is the least expensive option that reliably produces the artifact you need on the Mac you own. That can be Apple Dictation at no extra charge, a lower-priced local utility, or a subscription whose connected services are genuinely useful.
6. Verify the license and trial on the current checkout
Before paying, confirm the number of Macs, whether the license follows a person or device, the refund period, what happens after a trial, which updates are included, and whether a license server or store receipt is required. Save the receipt and installer according to the vendor’s terms.
A trial should be tested in the real destination apps, not only a demo box. Check microphone and Accessibility permissions, the global shortcut, names, numbers, punctuation, long pauses, insertion fallback, model download size, CPU and memory pressure, and behavior with no network connection.
7. Choose IraVoice only for its narrow fit
IraVoice 1.2.2 Local costs $79 once after a 3-day free trial that starts with the first dictation. A license covers one, two, or three computers at the same time (US $79, US $109, or US $149) and can be moved to a new computer. It runs on macOS 13+ on Apple silicon, Windows 10 or 11 (64-bit), and Linux (beta). Speech recognition runs on the computer with NVIDIA Parakeet after a one-time model download; the license checks in weekly and keeps working offline for 30 days.
Choose IraVoice when held-key dictation with Right Command on a Mac or Right Ctrl on Windows, on-device recognition, code names spelled from your Git project in terminals, editors, and coding agents, and one tool across Mac, Windows, and Linux match the job. The default model is English; other offline models cover 25+ languages.
Choose another product when you need a lower price, Intel Mac support, saved-file or meeting transcription, diarization, or a long searchable transcript history. IraVoice is not the universal winner and is not the cheapest pay-once option in this reviewed set.
