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

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

ProperDietPlan's answer:

People who want a realistic, preference-aware plan for weight loss, maintenance or muscle gain — busy individuals tired of generic diet PDFs who want targeted calories and macros without hiring a nutritionist. It suits budget-conscious, high-protein, meal-prep and balanced-diet eaters alike.

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.

ProperDietPlan's answer:

ProperDietPlan started from a simple frustration: generic diet plans ignore real food preferences and lifestyles, so people abandon them within days. We built an AI-driven planner that turns a short quiz into a plan people actually stick to — realistic, preference-aware, and paired with free educational content so users understand the reasoning behind their macros.
