Aqua Voice vs Resonant summary
Resonant is a free, local-first dictation app for Apple Silicon Macs: it runs open, on-device speech models, works fully offline, and keeps your audio on your machine. Aqua Voice is a managed cloud app built around Avalon, its own proprietary model, which scored 97.3% on the AISpeak benchmark and ranked #1 among proprietary systems on the public OpenASR leaderboard at its October 2025 debut. The honest tradeoff: Resonant wins on free unlimited local dictation and privacy, while Aqua wins on raw accuracy, real-time context, and breadth across Mac, Windows, and iPhone. Notably, both charge the same for their paid tier, $8/month billed annually ($96/year), so this is a choice about approach, not price.
Cloud accuracy vs on-device privacy
Resonant is built on a simple, opinionated idea: dictation should be free, fast, and never leave your device. Everything runs locally on Apple Silicon, so it works in airplane mode, on air-gapped networks, and without an account. That design is why Reddit threads keep recommending it as a free, offline alternative to Wispr Flow and Superwhisper. The cost of that approach is that transcription quality is bounded by what a small model can do on your laptop's Neural Engine.
Aqua Voice makes the opposite bet. It streams audio to Avalon, a proprietary model Aqua trained specifically for dictation, and uses live context from your screen to get names, jargon, and formatting right. That requires an internet connection, and your audio is processed in the cloud (Aqua is SOC 2 Type II). In exchange, you get higher accuracy, real-time correction, and the same experience on Mac, Windows, and iPhone rather than Apple Silicon only.
What model does Resonant use?
Resonant is refreshingly open about its stack: it runs open, on-device speech models rather than a proprietary in-house engine, and it names them publicly. Its own documentation says it ships Moonshine models optimized for Apple Silicon, and its writing covers the broader open-model family (Parakeet, Qwen, Whisper) that local apps draw from. Because these run entirely on your machine, they are chosen to be small and fast enough for the Neural Engine, which is a genuine engineering feat but also a ceiling on accuracy.
Aqua takes a different path. Avalon is Aqua's own model, built and tuned for dictation rather than adapted from a general-purpose open checkpoint, and it runs in the cloud where it is not constrained by a laptop's memory or battery. That is why a purpose-built model matters: the same words spoken into an off-the-shelf local model and into Avalon can produce very different transcripts, especially on technical terms, proper nouns, and messy real-world audio.
We built Avalon on a benchmark of real clips of developers and AI researchers talking naturally, and measured it against Whisper Large v3:
Model
AISpeak accuracy
Avalon (ours)
97.3%
Whisper Large v3
65.1%
Aqua publishes this comparison as its core proof point: on the AISpeak benchmark, Avalon scores 97.3% while Whisper Large v3, a widely used open model, scores 65.1%. Avalon also ranked #1 among proprietary systems on the public OpenASR leaderboard at its October 2025 debut. One honest caveat: Whisper is used here as a well-known reference for off-the-shelf open ASR, not as a stand-in for Resonant specifically. Resonant openly ships its own choice of open on-device models (such as Moonshine), so treat the 65.1% as an illustration of the general open-versus-purpose-built gap, not a measured score for Resonant.

Where Resonant wins
Free, unlimited local dictation. Resonant's free tier gives you unlimited on-device speech-to-text with no account and no word cap. Aqua's free Starter tier is capped at 1,000 lifetime words, so for basic, high-volume dictation that never needs the cloud, Resonant is simply the more generous starting point.
Privacy and offline by default. Because Resonant processes everything on your Mac, your audio never leaves the device, and dictation keeps working with no internet at all, whether on a plane or an air-gapped network. If your work is sensitive, regulated, or often offline, that local-only guarantee is hard to beat, and it is the main reason Resonant shows up on Reddit as a recommended private alternative.
One price note in Resonant's favor at the top of the funnel: you can do real work for $0 indefinitely. Aqua's free tier is meant as a trial rather than a permanent free plan, so if you never want to pay, Resonant is the better fit.
Where Aqua Voice is better
Higher benchmark accuracy
Avalon scored 97.3% on the AISpeak benchmark and ranked #1 among proprietary systems on the public OpenASR leaderboard at its October 2025 debut. Resonant publishes no comparable benchmark, and its on-device models are tuned for speed on the Neural Engine rather than top-end accuracy.
Real-time context awareness
Aqua reads live context from your screen to nail names, jargon, and formatting as you speak, and it corrects in real time. Resonant's local pipeline transcribes what it hears without that screen-aware context layer.
Mac, Windows, and iPhone
Aqua runs the same on macOS, Windows, and iPhone. Resonant is Apple Silicon Mac only, with Windows still in alpha and no mobile app, so it can't follow you across devices the way Aqua can.
A developer API, too
Beyond the app, Aqua exposes Avalon through an OpenAI-compatible developer API at $0.39/hour, so teams can build the same accuracy into their own tools. Resonant is an end-user app without a comparable hosted API.

How to decide
Pick Aqua Voice if: Choose Aqua Voice if accuracy is the priority, you dictate technical or domain-heavy content, you want real-time context and formatting, or you need the same tool on Windows and iPhone as well as Mac. You'll need an internet connection, and Pro is $8/month billed annually ($96/year) after the free Starter tier.
Pick Resonant if: Choose Resonant if you want free, unlimited dictation that runs entirely on your Apple Silicon Mac, you care most about privacy or working offline, and you don't need Windows, iPhone, or the last few points of accuracy. Its Pro tier matches Aqua at $8/month billed annually, but its free local tier may be all you ever need.
Aqua Voice is free to start, so you can compare it against Resonant on the words you actually dictate before paying anything.
Frequently asked questions
Is Resonant free?
Yes. Resonant's free tier includes unlimited local, on-device speech-to-text with no account required. Its paid Pro plan (cloud cleanup, rewrites, and summaries) is $8/month billed annually ($96/year), with a monthly option and a 7-day trial. Aqua's free Starter tier is capped at 1,000 lifetime words, and Aqua Pro is also $8/month billed annually.
Does Resonant use Whisper?
Resonant openly runs open, on-device speech models and names them publicly; its own docs say it ships Moonshine models optimized for Apple Silicon, and it discusses the wider open-model family (Parakeet, Qwen, Whisper). Aqua instead runs Avalon, its own proprietary model, in the cloud. Neither app hides its approach, they just make opposite choices.
Which is more accurate, Aqua Voice or Resonant?
Aqua publishes a 97.3% score on the AISpeak benchmark and an October 2025 debut at #1 among proprietary systems on the public OpenASR leaderboard. Resonant publishes no benchmark, and small on-device models generally trade some accuracy for speed and privacy. If raw accuracy on hard audio and technical terms matters most, Aqua has the edge.
Does Aqua Voice work offline?
No. Aqua is a managed cloud app: it streams audio to Avalon and needs an internet connection. Resonant is the opposite, running fully on-device so it works in airplane mode and on air-gapped networks. If offline use is a hard requirement, Resonant is the better fit.
What platforms does each app support?
Aqua runs on Mac, Windows, and iPhone (no Android) and supports 49 languages. Resonant runs on Apple Silicon Macs, with a Windows alpha and no mobile app, and supports around 40 languages. If you work across a Mac, a PC, and a phone, Aqua covers all three.
Is my audio private with each app?
Resonant keeps audio fully on your device by default; its paid cloud features send only transcript text to what it describes as zero-retention infrastructure. Aqua processes audio in the cloud and is SOC 2 Type II certified. Both are defensible, but if you want audio to never leave your machine, Resonant's local-only model is the stronger privacy guarantee.
Do Aqua Voice and Resonant cost the same?
At the paid tier, yes: both Aqua Pro and Resonant Pro are $8/month billed annually ($96/year). The real difference is the free tier. Resonant's free plan is unlimited local dictation, while Aqua's free Starter tier is 1,000 lifetime words, so Resonant is cheaper if you never need cloud features.
