Aqua Voice vs Handy summary
Aqua Voice and Handy both dictate into any app with a hotkey, on opposite philosophies. Handy is free and open-source, running open models (Whisper, Parakeet) locally on Mac, Windows, or Linux. Aqua Voice runs its own model, Avalon (97.3% on technical terms), in the cloud, with zero setup plus iPhone. Pick Handy for free and offline; Aqua Voice for accuracy and convenience, $8/mo billed annually.
Free and on-device vs managed and cloud
Handy is a free, open-source (MIT) dictation app from solo developer CJ Pais. You download it, it pulls open speech models onto your machine, and everything runs locally on Mac, Windows, or Linux. Your audio never leaves the device, there's no account, and there's nothing to pay.
Aqua Voice takes the opposite approach. We run our own model, Avalon, in the cloud, so there's nothing to download or configure, the model is larger and more accurate than what fits on a laptop, and it keeps improving without you updating anything. The tradeoff is honest: it's a paid, cloud service rather than a free, on-device one.
What models does Handy use?
Handy is open about its models: it runs OpenAI's Whisper (via whisper.cpp) and NVIDIA's Parakeet locally, and you pick which one. These are strong, general-purpose models, freely available and well-documented.
The tradeoff with general-purpose models is that they weren't designed for specialized vocabulary. Everyday speech is fine, but technical terms, programming keywords, and AI tooling are where they struggle. That's the gap a purpose-built model closes, so we trained our own and published its results.
We built Avalon on a benchmark of real clips of developers and AI researchers talking naturally, and measured it against Whisper Large v3, one of the open models Handy can run:
Model
AISpeak accuracy
Avalon (ours)
97.3%
Whisper Large v3
65.1%
On the public OpenASR leaderboard, Avalon ranked #1 among proprietary systems at its October 2025 debut, ahead of Whisper on that leaderboard. Handy also offers NVIDIA's Parakeet, which we haven't benchmarked head-to-head; either way, the technical-vocabulary gap is what matters most to developers and power users. Try Aqua Voice free.
Where Handy wins
Free and open-source. Handy is MIT-licensed and completely free, with the source on GitHub. If you want to read the code, self-host, or avoid a subscription entirely, that's a real advantage Aqua Voice doesn't offer.
Fully on-device and offline. Handy runs the model locally, so your audio never leaves your machine and it works with no internet connection. If on-device privacy is non-negotiable, Handy has the edge.
Linux and full control. Handy runs on Linux (Aqua Voice doesn't), and because it's open-source you can swap models and customize it. The flip side is that you manage the model and setup yourself.
Where Aqua Voice is better
Accuracy without the setup
Avalon is purpose-trained for technical and AI speech and benchmarked publicly: 97.3% on AISpeak where Whisper Large v3 scores 65.1%, and #1 among proprietary systems on the OpenASR leaderboard at its October 2025 debut. Handy's accuracy depends on which open model you download and how powerful your machine is.
Zero setup, always current
Aqua Voice runs server-side, so there are no models to download, no hardware requirements, and no configuration. The model keeps improving on its own, where a local tool is frozen to whatever you've installed until you update it.
Real-time on a bigger model
Because Avalon runs in the cloud, it streams text as you speak on a model larger than a laptop can run. On-device tools are gated by your machine: the more accurate the local model, the slower it goes.
iPhone and screen context
Aqua Voice runs on iPhone as well as Mac and Windows, on one subscription, and the desktop app reads the active window for context, code-aware in your editor, casual in Messages. Handy is desktop-only (Mac, Windows, Linux).
A model developers can build on
The same model is available through the Avalon API, OpenAI-compatible, at $0.39/hour of audio, so you can put Avalon-grade accuracy into your own tools.

How to decide
Pick Aqua Voice if: You want the most accurate dictation with nothing to set up; you dictate code, AI prompts, or technical terms and want accuracy you can verify; you want real-time cloud processing, iPhone support, and ongoing improvements; or you'd rather not manage a local model yourself.
Pick Handy if: You want a free, open-source tool; you need everything to run on-device and offline; you're on Linux; or you like reading the code, swapping models, and self-managing your setup.
Aqua Voice is free to start, so you can compare it against Handy on the words you actually dictate before paying anything.

Frequently asked questions
Is Aqua Voice a good Handy alternative?
It depends on what you value. Handy is free and open-source, and runs entirely on your own machine. Aqua Voice is a managed service on its own model, Avalon, with higher accuracy on technical speech (97.3% on AISpeak), zero setup, iPhone support, and ongoing improvements. If you want a free, on-device, do-it-yourself tool, Handy is great; if you want the most accurate dictation with nothing to configure, Aqua Voice is the stronger choice.
What's the difference between Aqua Voice and Handy?
They're built on opposite philosophies. Handy is free and open-source (MIT), running open speech models like OpenAI's Whisper and NVIDIA's Parakeet locally on your Mac, Windows, or Linux machine. Aqua Voice is a managed cloud app running Avalon, its own purpose-trained model, with real-time streaming, screen-context awareness, and iPhone support. Both dictate into any app with a hotkey.
Is Aqua Voice more accurate than Handy?
On technical and AI speech, yes. Handy runs general-purpose open models (Whisper, Parakeet), and its accuracy depends on which model and hardware you choose. Aqua Voice runs Avalon, trained specifically for technical vocabulary: it scores 97.3% on AISpeak (our benchmark of AI and technical terms) where Whisper Large v3 scores 65.1%, and it ranked #1 among proprietary systems on the public OpenASR leaderboard at its October 2025 debut.
Is Aqua Voice free like Handy?
Handy is fully free and open-source. Aqua Voice has a free Starter tier (1,000 words), then Pro is $8/month billed annually. You're paying for a purpose-built, benchmarked model, zero setup, real-time cloud processing, iPhone support, and ongoing model improvements and support, rather than running and maintaining an open model yourself.
Does Aqua Voice work offline like Handy?
No. Handy runs on-device, so it works offline and your audio never leaves your machine. Aqua Voice processes audio in the cloud to run the Avalon model, so it needs an internet connection. If fully offline, on-device dictation is a requirement, Handy is the better fit.
Does Aqua Voice run on Linux?
No. Aqua Voice runs on Mac, Windows, and iPhone. Handy also supports Linux, so if you need Linux dictation, Handy is the option. Aqua Voice covers iPhone, which Handy does not.
Why pay for Aqua Voice when Handy is free?
For accuracy and convenience. Avalon is purpose-trained and benchmarked publicly: on AISpeak it scores 97.3% to Whisper Large v3's 65.1% (Whisper is one of the open models Handy runs). Aqua Voice also requires zero setup (no model downloads or tuning), runs a large model server-side that no laptop can match, adds screen-context awareness and iPhone support, and keeps improving with ongoing updates and support. Handy is an excellent free, on-device option if you'd rather self-manage an open model.
Is Aqua Voice good for coding and AI prompting?
Yes, it's what Aqua Voice is built for. Avalon was trained on the speech developers and AI users produce, reaching 97.3% accuracy on technical terms like programming keywords, framework names, and CLI commands. It also reads the active app for context and offers the Avalon API for developers.
