Feature Comparison

Agent to Agent Testing Platform

Automated Scenario Generation

This feature enables the platform to create diverse test scenarios automatically. It simulates chat, voice, hybrid, or phone interactions, ensuring that AI agents are tested against a wide array of real-world situations. This helps in identifying potential flaws that could affect user experience.

True Multi-Modal Understanding

Agent to Agent Testing Platform goes beyond text-based interactions. Users can define detailed requirements or upload various inputs—such as images, audio, and video—to assess the expected outputs of the agents under test. This capability mirrors real-world scenarios, enhancing the testing process.

Diverse Persona Testing

With this feature, users can leverage a variety of personas to mimic different end-user behaviors and needs. By simulating interactions with personas such as International Caller or Digital Novice, organizations can ensure that their AI agents perform effectively across a diverse user base.

Autonomous Testing at Scale

This feature provides a comprehensive analysis of the AI agent from the perspective of synthetic end-users. It evaluates key metrics including effectiveness, accuracy, empathy, and professionalism. This ensures that the AI maintains consistent intent and tone across various interactions.

Dual-Engine On-Device Recognition

Hush Touch doesn't rely on a single method. It intelligently blends Apple's DictationTranscriber for natural flow and punctuation with SFSpeechRecognizer to spot custom vocabulary. This dual-input is then refined with an Apple Intelligence final pass. The magic? Every step of this process happens on your Mac. This means no lag waiting for a cloud server and, crucially, your private conversations and drafts never leave your device, setting a new bar for local processing power.

Adaptive Custom Vocabulary & Learning

This is where Hush Touch moves from a simple transcriber to a smart writing assistant. You can manually add up to 500 terms—perfect for technical jargon, brand names, or medical terminology. Even better, it learns automatically. When you correct a transcription mistake, Hush Touch detects it and adds the right word to your personal vocabulary. It even creates per-app profiles, boosting relevant terms whether you're in your code editor or email client.

Smart Text Processing & Hands-Free Commands

The app actively cleans up your spoken word in real-time. It strips out filler words ("um," "like," "you know"), auto-corrects common flubs, and can format numbered lists from your speech. For true hands-free operation, use a Siri shortcut or say "Okay send message" to dispatch an email. It auto-inserts text after a pause and supports a double-tap hotkey to stop listening, making the entire dictation-to-insertion flow seamless.

Lightweight Design & Context Modes

Weighing in at just 5.5 MB, Hush Touch is a marvel of efficiency. It launches in a flash and runs without bogging down your system. To further enhance accuracy, it offers four distinct context modes: General, Email, Code, and Notes. Switching modes tailors the engine's focus, helping it better predict punctuation and vocabulary relevant to the task at hand, from writing a formal email to commenting code.

Use Cases

Drafting Long-Form Content and Reports

For writers, researchers, and students, speaking ideas is often faster than typing them. Hush Touch allows you to dictate drafts of articles, essays, or reports naturally. Its smart punctuation and paragraph formatting let you speak in complete thoughts, while the on-device privacy ensures your unpublished ideas and sensitive research data remain completely confidential throughout the creative process.

Managing Professional Communication

Tackle an overflowing inbox hands-free. Dictate emails and messages with tone-appropriate phrasing aided by the Email context mode. The ability to say "Okay send message" allows you to compose and send replies without ever touching the keyboard, perfect for when you're multitasking, on the move, or dealing with repetitive communication throughout a busy workday.

Technical and Specialized Documentation

Software engineers, doctors, lawyers, and academics finally have a dictation tool that understands their language. By learning complex terms like "Kubernetes," "metatarsophalangeal," or legal citations, Hush Touch accurately transcribes technical notes, patient observations, code comments, and research summaries that would stump generic cloud-based services, saving immense time on corrections.

Accessible and Ergonomic Computer Use

For individuals with RSI, carpal tunnel, or other conditions that make typing painful, Hush Touch provides a robust, private alternative for controlling their Mac. The fully hands-free operation via Siri integration and voice commands enables full participation in digital work and communication without strain, all maintained with the dignity of complete data privacy.

Hush Touch | Voice-to-Text for MacOS FAQ

Is Hush Touch really 100% offline and private?

Yes, absolutely. This is its cornerstone feature. Every component—from the two Apple speech recognition engines to the Apple Intelligence final pass—processes your audio directly on your Mac. No audio or transcript data is ever sent to external servers. Your voice input and the resulting text never leave your computer, ensuring total privacy.

How does the vocabulary learning actually work?

Hush Touch employs adaptive learning. When you manually correct a word in the transcribed text, the app detects this correction and automatically adds the intended word to your personal vocabulary list. It also uses frequency weighting, so terms you use often in specific apps (like "diagnosis" in your notes app) become prioritized, making the engine smarter with each use.

Can I use Hush Touch completely hands-free?

You can. You can activate dictation using a Siri voice command ("Hey Siri, start touch"). Once listening, it will automatically insert the transcribed text after a short pause (roughly 2 seconds of silence). You can also use voice commands like "Okay send message" to send an email or message, and configure a hotkey to stop listening with a double-click.

What happens after the 7-day free trial?

The free trial gives you full access to all features for 7 days. After that, you need to purchase a lifetime license to continue using the app. There is no subscription. It's a single, one-time payment of $20 that grants you permanent access to the app and all its current features, with no recurring fees.
