UmamiQR's answer

UmamiQR is unique because it combines digital QR menus with AI-powered menu management.

The QR code stays the same while the menu can be updated live behind it.

UmamiQR's answer

UmamiQR is mainly built for restaurants, cafes, food trucks, bakeries, cloud kitchens, and small food businesses that want an easy way to create and manage a digital menu. It is especially useful for owners and managers who do not want to deal with technical setup, design tools, POS integrations, or repeated menu reprinting.

Diffyn's answer:

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

UmamiQR's answer

UmamiQR was created to make digital menus easier for restaurant owners. Many small food businesses still rely on printed menus or QR menu tools that require manual updates and technical effort. UmamiQR solves that by letting owners create a digital menu, manage it with plain-language AI prompts, and share it instantly with a QR code. Its goal is to give restaurants a modern, low-friction menu experience without the cost or complexity of traditional restaurant software.

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.
