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.

SocialDeck's answer:

The project started when our team of social media enthusiasts noticed a growing "privacy gap" on Instagram. We realized that many people felt hesitant to view stories because of the social pressure of the "seen" notification. We built SocialDeck.ai to democratize access to public information, giving users the freedom to explore content without the fear of being tracked, all while maintaining a clean, ad-light interface that prioritizes user experience over profit.

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.

SocialDeck's answer:

The uniqueness of SocialDeck’s tool lies in its "Zero-Footprint" philosophy combined with extreme speed. Unlike many tools that require a browser extension or display intrusive ads, our viewer is a pure web-based solution. It offers a seamless, high-definition (HD) preview and download experience that bypasses the need for an Instagram API login, ensuring that the user’s identity remains 100% encrypted and hidden from the story creator's "seen" list.
