TL;DR

TL;DR: Aqua Voice is a YC W24-backed desktop and mobile dictation app that uses a proprietary Avalon transcription model to deliver sub-50ms startup, 97% accuracy on technical vocabulary, and natural-language editing commands across Cursor, Slack, Gmail, ChatGPT, and any text field on your system.

Source and Accuracy Notes

What Is Aqua Voice?

Aqua Voice is a voice-driven text input tool built by YC W24 founders Finn and Jack. Finn has been using dictation software since sixth grade to manage dyslexia, and the pair built Aqua after years of frustration with existing tools that focus on raw transcription accuracy but ignore the real problem: turning messy speech into clean, correctly formatted text.

The product ships as a desktop app for Mac and Windows, plus an iPhone app (iOS 17.0+, 42.7 MB). It sits as a system-wide input method, so you can dictate into any text field — code editors, email clients, chat apps, terminal prompts — without switching context.

How Aqua Voice Works

Aqua runs six models in parallel to handle the full pipeline from audio to formatted text:

  1. MoE transcription — a mixture-of-experts speech model handles real-time audio-to-text
  2. Language model sync — determines what should appear on screen as quickly as possible
  3. Intent classification — decides whether your speech is content (transcribe verbatim), a command (execute it), or a rough draft (clean it up)
  4. Formatting pass — applies context-aware formatting based on the target app

The result, per the founders’ HN post:

  • Startup in under 50ms
  • Text insertion in about 1 second (sometimes as fast as 450ms)
  • 97% accuracy on technical vocabulary (API endpoints, model names, programming terms) where generic models score below 70%

Setup and Installation

Mac / Windows Desktop

Download from withaqua.com/download or aquavoice.com/download. The app installs as a system-wide input method.

iPhone

Install from the App Store (requires iOS 17.0+).

Using Aqua Voice

Once installed, activate dictation with a shortcut (configurable). Speak naturally — Aqua handles punctuation, filler-word removal, and formatting. You can also issue editing commands:

"Remove filler words, this is a slack message"
"Translate this to Japanese"
"Make this title case"
"Spell Toni T-O-N-I"
"Format the numbers like $10m"

Aqua works inside any app that accepts text input: Cursor, VS Code, Slack, Gmail, ChatGPT, Claude, terminal, and more.

Supported Languages

Aqua Voice supports six languages for transcription:

  • English
  • French
  • German
  • Japanese

Privacy and Data Handling

Aqua Voice is not a fully local/offline tool. The product uses cloud processing for transcription, and the privacy policy references sharing data with service providers including OpenAI. The founders have been transparent about this in HN comments.

If you need fully local, offline dictation, consider open-source alternatives like VoiceInk or whisper-dictation.

Aqua maintains a Vanta trust page for security compliance details.

Practical Evaluation Checklist

  • [ ] You dictate into code editors (Cursor, VS Code) and need technical term accuracy
  • [ ] You have dyslexia, RSI, or another condition that makes typing difficult
  • [ ] You want voice input that works system-wide, not just in one app
  • [ ] You’re comfortable with cloud-based transcription (not fully offline)
  • [ ] You need sub-second latency for real-time dictation flow
  • [ ] You work in English, French, German, Japanese, Russian, or Spanish

FAQ

Q: Is Aqua Voice open source? A: No. Aqua Voice is a proprietary product. The founders have not announced plans to open-source any part of the platform.

Q: Does Aqua Voice work offline? A: No. Aqua Voice requires an internet connection for cloud-based transcription. The product uses OpenAI as a service provider for some processing.

Q: How does Aqua Voice compare to Apple Dictation or Whisper? A: Aqua Voice focuses on turning messy speech into clean, formatted text with natural-language editing commands. Apple Dictation and raw Whisper models handle transcription but don’t distinguish between content and commands, and don’t auto-format output.

Q: Can I use Aqua Voice with ChatGPT or Claude? A: Yes. Aqua Voice works as a system-wide input method, so you can dictate directly into ChatGPT, Claude, or any other text field on your system.

Q: What platforms are supported? A: Mac, Windows, and iPhone (iOS 17.0+). The founders have mentioned plans to support Linux.

Conclusion

Aqua Voice fills a real gap in the dictation market by treating voice as a first-class input method rather than just a transcription engine. The combination of sub-50ms startup, 97% technical-term accuracy, and natural-language editing commands makes it viable for developers, writers, and anyone who thinks faster than they type. The cloud dependency is a trade-off — you get speed and accuracy but lose offline capability and full data privacy. At $12.99/month or $119/year, it’s priced competitively against other AI-powered productivity tools.
