What's the story behind your product?

Sendwishonline's answer

Sendwishonline was created after identifying a common workplace problem: teams wanted to wish someone together, but there was no simple way to do it digitally. Offices often relied on paper cards or had to send multiple single eCards, which felt disconnected and inconvenient—especially for remote teams.

To solve this, Sendwishonline introduced a shared digital space where everyone can contribute in one place. Messages from multiple people are combined into a single wishboard or slideshow, enhanced with photos, GIFs, music, and attractive designs. The platform was built to be easy to share, quick to use, and accessible to everyone, offering a free option at a time when many similar tools were paid.

The goal behind Sendwishonline is to make group wishes more meaningful, collaborative, and effortless for modern teams and workplaces.

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.
