Short answer: VoiceInk is a well-built, open-source, one-time-payment voice-to-text app that runs only on macOS (Apple Silicon, macOS 14.4+). AICHE runs on macOS, Windows, Linux, iPhone, iPad, Apple Watch, Android, Chrome, Obsidian, and a REST API - 9 platforms, with a team plan and a Software Development recognition profile, starting at $3.99/mo billed annually. If you live entirely inside macOS and want a local-first lifetime purchase, VoiceInk is a solid pick. If your day touches a Linux box, a Windows laptop, an Android phone, a browser text field, or your own scripts, you need the wider platform reach.
What VoiceInk is selling
VoiceInk pitches itself as "the best open-source alternative to Superwhisper & Wispr Flow." The homepage tagline is "write at the speed of thought," and the positioning is built around three things: it runs locally on your Mac, the source is public on GitHub under GPL v3, and you pay once instead of every month. Their headline use case is the same as most dictation apps - press a hotkey, talk, get text inserted into whatever app you're in.
The local-first claim is real. By default, VoiceInk transcribes audio on-device using Whisper or Parakeet models, with Apple's native speech recognition and Ollama also supported. Their privacy policy spells out that audio, transcripts, custom vocabulary, and settings stay on your Mac unless you turn something on. Cloud is opt-in: users can plug in their own API keys for OpenAI, Anthropic, Groq, Gemini, Mistral, Deepgram, ElevenLabs, Speechmatics, and a handful of others to polish transcribed text. Eleven supported providers, BYO key, you pick who sees your text.
The product also ships a "Power Mode" that auto-switches recognition settings (model, prompt, behavior) based on the active app, a personal dictionary for custom words and replacements, and small enhancement presets (Polish, Email, Chat, Post) plus an AI Assistant for follow-up questions. Pricing is $25 lifetime for one Mac, $39 for two Macs ("most picked"), $49 for three Macs. Free trial download, 14-day money-back guarantee. The free iOS / iPad / Watch / Vision companion is a separate app on the App Store that syncs back to the desktop.

Where VoiceInk wins
Three places, plainly.
Open source and auditable. VoiceInk's code is on GitHub under GPL v3. You can read what the app actually does instead of trusting a marketing page. For users who care about that - and there's a real audience that does - this is the headline. AICHE is closed source. We publish what we do, but you take our word for it.
One-time payment, no subscription. $25 for one Mac, $39 for two, $49 for three. If you only need dictation on a single Mac for the next five years, the math beats every subscription product including AICHE. A $3.99/mo subscription over five years is roughly $240. VoiceInk Solo is $25 forever. The tradeoff: no Windows, no Linux, no Android, no API, no team plan, no developer profile, no E2EE multi-device sync. But for a solo Mac user with no plan to move, the price is hard to beat.
Truly local processing on macOS by default. Whisper or Parakeet run on your machine. Audio never leaves the Mac unless you specifically enable a cloud enhancement step with your own API key. AICHE is honest about being cloud transcription (Groq, audio purged within seconds). If "no audio ever leaves my machine, full stop" is your hard requirement, VoiceInk meets it and AICHE doesn't.
Honorable mentions: Power Mode (per-app context switching) is a slick feature; the BYO-key model for enhancement gives privacy-conscious users a lot of control; the solo developer ships fast - 120 releases as of v1.77 and an active Discord.
If you're a Mac-only indie developer who wants a one-time-payment, open-source, local-by-default dictation app and you don't need any of the things in the next section, VoiceInk is a good choice and we'll be the first to say so.
Where AICHE wins
Platform coverage
This is the headline.
VoiceInk's paid product is macOS only. Apple Silicon, macOS 14.4+. If you have an Intel Mac, you're out. The free iOS / iPad / Watch / Vision companion exists, but it's a separate, free app from the paid macOS product, and App Store reviewers report it's buggy ("the voice recognition doesn't work as well as the one on macOS").
AICHE runs on:
- macOS (Intel and Apple Silicon)
- Windows
- Linux (.deb, .rpm, AppImage, Flatpak)
- iPhone (iOS 15+)
- iPad
- Apple Watch
- Android (phone and tablet, home-screen widget)
- Chrome extension (inserts into browser text fields)
- Obsidian plugin (voice notes inside Obsidian)
- REST API (Pro tier)
9 platforms. Same hotkey muscle memory on the desktops, same account, same custom vocabulary, same transcripts synced across all of them. If your day involves moving between a Windows work laptop, a personal Mac, a Linux dev box, an Android phone, and a Chrome tab, AICHE is one product. VoiceInk is one Mac.
Real public REST API
AICHE Pro exposes a REST API. You can call it from a shell script, a CI job, a Slack bot, a custom IDE plugin, whatever you build. VoiceInk does not advertise a public API. If you're the kind of person who wants to automate around voice transcription (or even build something on top of it), this matters. If you're not, it doesn't.
Software Development recognition profile
AICHE Pro ships a Software Development recognition profile - a recognition mode tuned for code identifiers, CLI flags, library names, and developer jargon. Speak --no-cache-dir and you get --no-cache-dir, not "no cash dur." Speak useState, kubectl, pnpm, OAuth, tsconfig, you get them spelled right.
VoiceInk relies on the user's personal dictionary. You can teach it the words you use, one at a time. There's no built-in dev profile. Voibe's review of VoiceInk (Voibe is a competing dictation product, disclosed in the post) explicitly notes "no VS Code or Cursor support" and that "developers who dictate code comments or documentation miss out on file name resolution and workspace-aware vocabulary." For someone whose voice transcripts are mostly normal English prose, that's fine. For someone whose transcripts are 30% code-flavored tokens, the difference is felt in every dictation.
Voice Code for AI coding agents
AICHE Pro has a Voice Code mode designed for the agent loop: pause-aware auto-send into Claude Code, Codex, Cursor, and Antigravity. You speak the prompt, you stop, AICHE ships it to the agent. No Enter, no Send button. Voice confirmations let you approve or reject agent actions by voice.
VoiceInk inserts text into whatever has the cursor, the same as any system-wide dictation app. There's no agent-loop feature. If you spend your day dictating into coding agents and you want the workflow tuned for that, AICHE is built for it. If you mostly dictate into Notes or Mail, that's table stakes and either app handles it.
Real team plan
AICHE Pro includes a team plan: seats, roles, admin panel, unified billing. If you're equipping a team of writers, support agents, or developers with voice dictation, you manage them in one place.
VoiceInk licenses are per-device individual. The "Extended" $49 tier covers three macOS devices for one user. There's no team admin, no shared billing, no shared vocabulary across team members. For a team of five, you'd buy five Solo licenses (or three Extended licenses if you're doing it that way) and manage them independently.
Speed and the post-Whisper pipeline
AICHE: sub-100ms cold start to recording. 15 minutes of audio becomes ready-to-use text in roughly 3 seconds. For comparison, raw local Whisper Large v3 on current Apple Silicon processes 15 minutes of audio in 40-60 seconds before any post-processing - an order of magnitude slower on the same hardware.
The speed gap is half the story. The other half is what happens after Whisper. Raw Whisper output is not finished text: the model regularly produces phantom phrases ("thanks for watching" / "subscribe" inserted into unrelated recordings is a documented Whisper failure mode), filler-word artifacts, and mistranscribed proper nouns. AICHE runs a multi-stage polish pipeline after Whisper - hallucination filter built from empirical dictionaries, filler / stutter removal, custom vocabulary enforcement, profile-specific recognition tuning, fast LLM polish through Groq with zero retention. That pipeline is the product, not the Whisper call. It runs in ~3 seconds because the polish stage alone needs more compute than a laptop offers at flow-state speed.
VoiceInk: independent reviewer Danny Smith, who switched from Wispr Flow to VoiceInk, wrote: "It's slightly slower to respond to keypresses than Wispr, which means I often lose the first or last word." Local Whisper / Parakeet inference speed depends on your Mac. On a current M-series, it's good. On older hardware, it's slower than cloud. Local Whisper Large is also GPU-heavy and drains laptop battery noticeably faster than a cloud round-trip with ~no client compute.
The tradeoff is real: cloud transcription needs internet on desktop (AICHE doesn't pretend otherwise; on a plane with no Wi-Fi, VoiceInk's pure-local mode wins for real-time transcription). AICHE's answer for that case is a local encrypted queue - recordings save on disk and process automatically when connectivity returns. If you're tied to your desk on fast internet, AICHE is faster end-to-end and ships polished output rather than raw Whisper. If you're offline often and want real-time results without any cloud round-trip, VoiceInk fits that case.
Multilingual stability
AICHE supports 99 transcription languages with the same engine across every platform. Speak Russian into your Linux laptop, get Russian text. Mobile UI is localized in 28 languages.
VoiceInk relies on Whisper and Parakeet. App Store reviews on the iOS companion: "The current local model, Parakeet, doesn't seem to work well for multi-language use." Reviewers report Parakeet sometimes misdetects language when you switch mid-dictation. Whisper handles multilingual better but at a speed/size tradeoff.
Cross-device sync
AICHE syncs notes end-to-end encrypted across all 9 platforms with AES-256-GCM at rest and Argon2id-derived keys (you set the passphrase). Record on your phone walking back from coffee, the note is on your Linux desktop when you open it.
VoiceInk's paid product is one Mac (or 2-3 Macs at higher tiers). The iOS companion syncs back to the desktop. Cross-device transcript sync at the scale of AICHE - Mac to Linux to Android to iPhone, all encrypted - isn't part of the product.
Price for the broad feature set
VoiceInk Solo is $25 lifetime, which is genuinely cheap. But it's one Mac, no API, no team, no Windows, no Linux, no Android.
AICHE Personal annual is $3.99/mo ($47.99/yr), 3 devices, every platform, AI cleanup, multilingual, E2EE sync. Pro annual is $8.33/mo ($99.99/yr), 10 devices, plus API, team plan, Software Development profile, Voice Code for agents. See pricing for the full breakdown.
7-day free trial, no credit card.
Privacy: two honest models
This isn't a contrast where one of us is hiding something. Both apps publish their model and both are roughly honest about it.
VoiceInk: local-first by default. Whisper or Parakeet run on your Mac. Audio doesn't leave the device unless you turn on opt-in cloud enhancement with your own API key. The source is on GitHub under GPL v3, so the claim is auditable - you can read what the binary actually does, not just what the marketing says. Retention on-device is indefinite by default with an optional 7-day auto-cleanup. The privacy policy doesn't describe analytics or telemetry.
AICHE: cloud transcription via a named provider (Groq). Audio is streamed, processed in seconds, and discarded - typically 2-3 seconds during processing, within 1 second after processing worst case. No persistent audio storage. Transcripts live locally on your device by default; cloud sync is opt-in and end-to-end encrypted with AES-256-GCM (Argon2id-derived passphrase key that we never see). Modern TLS in transit, with certificate pinning on iOS and Android. No global keystroke logging, no clipboard monitoring outside explicit user action, no active-window-title transmission, no background recording. On desktop, no automatic telemetry - diagnostics flow only when you initiate them (the OS-level "share with developer" prompt after a crash, or a manual "Send Diagnostic Report" button). On mobile, Firebase for ad attribution is the only third-party telemetry.
Different models, both stated plainly. If your hard requirement is "no audio ever leaves my machine," VoiceInk meets it and AICHE doesn't. If your requirement is "audio doesn't sit on a server, transcripts are E2EE across all my devices, and the company isn't logging my keystrokes," both apps meet it - but only AICHE syncs across more than one Mac.
What to look for in any voice app you're evaluating: a named transcription provider (not "the cloud"), a stated audio retention window, an E2EE option for synced transcripts, and an explicit statement about what the binary monitors outside recording (keystrokes, clipboard, window titles). Both AICHE and VoiceInk publish this. Many competitors don't.
Common questions
Q: I'm on Linux. Which one of these works for me?
A: AICHE. VoiceInk is macOS only (Apple Silicon, macOS 14.4+). AICHE ships on Linux as .deb, .rpm, AppImage, and Flatpak. Same global hotkey (Ctrl+Alt+R), same recording model, same custom vocabulary as the Mac and Windows builds.
Q: I'm on Windows. Same question.
A: AICHE. VoiceInk has no Windows build. AICHE ships a native Windows app with Ctrl+Alt+R as the global hotkey, full E2EE sync to your other devices, and the Software Development profile if you're on Pro.
Q: I dictate a lot into Cursor and Claude Code. Which handles snake_case and CLI flags correctly?
A: AICHE, when you turn on the Software Development profile (Pro). It's a recognition mode tuned for code identifiers, library names, and CLI flags. Speak --no-cache-dir and you get --no-cache-dir. VoiceInk relies on your personal dictionary - you'd have to teach it your code tokens one by one, and there's no equivalent built-in profile.
Q: I'm a privacy purist. I don't want my audio touching any cloud, ever.
A: VoiceInk is the better fit. By default, Whisper or Parakeet run on your Mac and audio doesn't leave the device. AICHE is cloud transcription (named provider, audio purged within seconds), so if "audio never leaves my machine" is your bright line, AICHE doesn't clear it.
Q: I only own one Mac and I hate subscriptions. Why not just buy VoiceInk for $25?
A: That's a reasonable read. If your work is entirely on one Mac, you don't need an API or team plan, you don't write much code, and you're confident about subscription fatigue, VoiceInk Solo at $25 is a good deal. The honest version of this comparison: if AICHE doesn't have features you'll use, the cheap one-time payment wins.
Q: I work on a Mac at home and a Windows laptop at work. What's the workflow?
A: AICHE - the same account, the same custom vocabulary, the same encrypted transcripts on both machines, same hotkey behavior. VoiceInk doesn't have a Windows build, so you'd need a second product for the work laptop.
Q: Does AICHE work offline?
A: Not for real-time transcription on desktop. It streams audio to a cloud provider for processing. AICHE's answer for offline moments is the never-lose-your-recording guarantee: the recording saves to a local encrypted queue (AES-256 on disk), and the queue processes automatically the moment connectivity returns - so a plane, subway, or basement doesn't cost you the recording. If you need genuine offline transcription that produces text right then with no network, VoiceInk's local Whisper / Parakeet is the answer.
Q: Open source matters to me. AICHE isn't open source, right?
A: Right. AICHE is closed source. We publish what we do (audio purged within seconds, named provider, E2EE sync, no keystroke logging, no window-title transmission), but you take our word for it. VoiceInk is GPL v3 on GitHub - readable, buildable from source, auditable. If that's a hard requirement, VoiceInk wins.
Q: I run a team. Five seats, want one bill.
A: AICHE Pro. Real team plan with seats, roles, admin panel, unified billing. VoiceInk licenses are per-device individual; there's no team admin or shared billing.
The honest summary
VoiceInk is a good Mac app. The developer ships fast, the source is public, the price is genuinely fair, and the local-first model is real. For a Mac-only solo user who doesn't need an API, a team plan, a dev-tuned profile, or any non-Apple device support, it's a solid pick.
AICHE is built for users whose lives don't fit on one operating system. macOS, Windows, Linux, iPhone, iPad, Apple Watch, Android, Chrome, Obsidian, and an API. A team plan that's actually a team plan. A Software Development profile for people whose transcripts are full of code. Voice Code for AI agents. End-to-end encrypted sync across all of it. Starting at $3.99/mo with a 7-day free trial, no credit card.
Result: if you live on macOS and want a one-time-payment, open-source, local dictation app, VoiceInk is honest about what it is and worth the price. If your work crosses operating systems, you write code, you build automations, you run a team, or you want one voice layer for every device you touch, AICHE is the broader product.
Try it now: open a 7-day AICHE trial, press ⌃+⌥+R on Mac or Ctrl+Alt+R on Windows/Linux, and dictate one prompt into the tool you use most.
