Feature Comparison

Agent to Agent Testing Platform

Autonomous Multi-Agent Test Generation

Leverage a dedicated team of 17+ specialized AI agents designed to act as synthetic testers. These agents autonomously generate diverse, complex test scenarios, simulating countless real-world user interactions to ruthlessly uncover edge cases, bias, toxicity, and hallucination risks that human testers would never think to try, ensuring comprehensive coverage.

True Multi-Modal Understanding & Testing

Go far beyond text-based testing. Define requirements or upload PRDs (Product Requirement Documents) that include diverse inputs like images, audio, and video files. The platform gauges your AI agent's expected output against these multi-modal inputs, mirroring the complex, real-world scenarios your agent will actually face, from analyzing an uploaded image to processing a voice command.

Diverse Persona Testing at Scale

Simulate real human diversity with a library of customizable user personas, such as the "International Caller" or "Digital Novice." This allows you to validate how your AI agent performs for different user types, behaviors, and needs, ensuring inclusivity and effectiveness across your entire user base through autonomous, large-scale synthetic user testing.

Actionable Evaluation with Risk Scoring

Get beyond pass/fail results. Receive detailed, actionable reports in minutes with deep visibility into business metrics, conversational flow, and interaction dynamics. Integrated risk scoring highlights potential areas of concern, allowing teams to prioritize critical issues and optimize performance based on concrete data, not guesswork.

Dual-Engine Recognition

Hush Touch employs a dual-engine recognition system that combines the strengths of DictationTranscriber and SFSpeechRecognizer. This powerful pairing not only ensures natural flow and accurate punctuation but also boosts your custom vocabulary recognition for more precise transcription results.

Custom Vocabulary

With the ability to learn from your corrections, Hush Touch can store up to 500 unique terms, including technical jargon and brand names. This feature allows the app to adapt to your specific needs, making it particularly beneficial for professionals in specialized fields who require accurate terminology.

Smart Text Processing

Hush Touch features intelligent text processing capabilities that remove filler words and auto-correct common errors in real-time. It even allows you to format lists and voice snippets for repeated phrases, enhancing your dictation experience and resulting in cleaner, more polished output.

100% On-Device Privacy

Privacy is paramount with Hush Touch, as it processes all voice data entirely on your Mac. This means there is no reliance on cloud services, ensuring that your voice and text are kept confidential. Enjoy peace of mind knowing that your data is secure and never leaves your device.

Use Cases

Agent to Agent Testing Platform

Pre-Production Validation for Customer Service Bots

Before launching a new customer support chatbot, use the platform to simulate thousands of customer inquiries, from simple FAQ requests to complex, emotional, or poorly-phrased problems. Validate intent recognition, escalation logic to human agents, policy compliance, and tone to ensure a flawless, brand-safe launch.

Compliance and Safety Auditing for Financial AI Agents

For AI agents in regulated industries like finance or healthcare, proactively test for data privacy violations, biased lending or advice, and hallucinated information. The platform's specialized agents (e.g., Data Privacy Agent) can systematically probe for compliance failures and safety risks, providing an audit trail for regulators.

Continuous Regression Testing for Voice Assistants

Every update to your voice AI's model or knowledge base risks breaking a previously working function. Implement autonomous regression testing suites that run with each deployment, checking for consistent intent understanding, tone, and reasoning across key user journeys to prevent updates from degrading the customer experience.

Performance Benchmarking Across Agent Versions

When developing a new version of your AI agent, use the platform's scenario library to run identical test batteries against both the old and new versions. Objectively compare key metrics like effectiveness, accuracy, and empathy to quantify improvement and ensure no regression in core capabilities before switching versions.
