Questions & Answers

As answered by people managing NVOX and Diffyn.

Why should a person choose your product over its competitors?

NVOX's answer

NVOX provides a clinically valid ADHD diagnostic process at an accessible price. Assessments are based on AI-powered analysis and behavioral data, reviewed and signed by both a licensed MD and a PhD in educational psychology. The final report is widely accepted by schools, universities, and institutions for accommodations. Compared to manual Zoom-based evaluations, NVOX offers a faster, more affordable, and institutionally recognized alternative, without compromising on quality.

Diffyn's answer:

Diffyn is the platform that specializes on both change management and multi-model analysis.

What makes your product unique?

NVOX's answer

NVOX is the only ADHD diagnostic platform that combines AI-driven analysis, biometric tracking (like eye movements and blink rate), and psychologist validation into a fully remote process. While other services rely on Zoom-based evaluations or self-reports alone, NVOX blends automation with clinical rigor, delivering results in days, not weeks.

Diffyn's answer:

Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.

How would you describe the primary audience of your product?

NVOX's answer

Our primary audience is parents of children aged 8–18 in the United States who are struggling with school, attention, or behavior, and need a clear, professional ADHD diagnosis. We also serve adults seeking documentation for college accommodations or workplace support. Support for adults over 18 is expanding and will soon be available more broadly.

Diffyn's answer:

Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.

What's the story behind your product?

NVOX's answer

NVOX was founded by Shlomi (David) Grandes, who was diagnosed with dyslexia and ADHD at age 30 after a lifetime of frustration, failure, and being misunderstood by the education system. Despite being identified as gifted in early childhood, he was labeled a failure throughout school. A chance conversation with a psychologist working in a U.S. maximum-security prison exposed a shocking reality: over 50% of inmates have undiagnosed ADHD, and many of them could have been helped earlier with proper diagnosis and intervention. That realization drove him to act. Together with childhood friend and physician Dr. Johnathan Leemor, and AI expert Gil Cohen, David developed a scalable diagnostic platform that combines machine learning, biometric analysis, and clinical oversight. The result is NVOX: an AI-powered ADHD assessment system that delivers fast, accurate, psychologist-reviewed results from the comfort of home. Unlike traditional diagnostic processes, NVOX was designed from the ground up to address systemic failures - long wait times, high costs, and inconsistent evaluation methods. David fully funded NVOX personally, ensuring the company remains mission-driven and free from short-term investor pressure. Today, NVOX is setting a new standard for ADHD and learning disability diagnostics - fast, accessible, clinically sound, and built by people who lived it.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.

Which are the primary technologies used for building your product?

Diffyn's answer:

React, Next.js, POSTGRESQL
