Questions & Answers

As answered by people managing Diffyn and Nexwin AI.

What makes your product unique?

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.

Nexwin AI's answer:

Nexwin is an Australian-first AI receptionist. Unlike generic global voice tools, it speaks in a natural Australian voice, understands local accents and suburb/street names, keeps data onshore, and is backed by Sydney-based support. It also covers both key inbound channels with two products — N-Voice for phone calls and N-Chat for website chat — and publishes transparent pricing rather than hiding it behind a quote.

Why should a person choose your product over its competitors?

Diffyn's answer

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

Nexwin AI's answer:

Because it's built for Australian businesses and priced in the open. Many rivals are quote-only or optimised for US/enterprise markets; Nexwin publishes plans (N-Voice from A$249/mo +GST, N-Chat from A$124/mo +GST), sets up in minutes via simple call forwarding with no new hardware, and has no lock-in contracts plus a 7-day free trial. You get a local, natural-sounding receptionist that never sends callers to voicemail — at a predictable price.

Which are the primary technologies used for building your product?

Diffyn's answer

React, Next.js, POSTGRESQL

Nexwin AI's answer:

Nexwin combines large language models for natural conversation, speech-to-text and text-to-speech for real-time voice, and cloud telephony for call handling and forwarding, delivered through a modern cloud web platform.

How would you describe the primary audience of your product?

Diffyn's answer

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

Nexwin AI's answer:

Australian small and medium service businesses that lose work to missed calls — tradies (plumbers, electricians, builders, HVAC), medical and dental clinics, real estate agencies, and other appointment-driven or enquiry-driven businesses that can't afford to miss after-hours or overflow calls.

What's the story behind your product?

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.

Nexwin AI's answer:

Founded in 2022, Nexwin was started by a technical founder with 20+ years in software who saw Australian service businesses losing real revenue every time a call went unanswered — voicemail rarely converts, and hiring a receptionist or traditional answering service is costly and still misses after-hours. As AI voice matured, the opportunity became clear: a genuinely Australian AI receptionist that answers 24/7, books the job, and only escalates real emergencies. Nexwin now offers N-Voice and N-Chat to service businesses across Australia.

Who are some of the biggest customers of your product?

Nexwin AI's answer:

Small and medium businesses and real estate agencies and main tradies
