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.

GetQRcard's answer:

I built GetQRcard because it was a service I personally needed and could not find in the form I wanted: simple, app-free, and genuinely free for individual users. A digital business card should not become obsolete when a phone number or job title changes. That led to the permanent QR code and editable contact page. To keep personal use free, the business model is limited to paid organizational needs such as bulk creation, centralized administration, and large-scale email signature deployment.
