Any advice on differentiating such idea in the YC application, from the herd, building services (an app/website where good design, paired with user traction stands out)?

Shall we focus on? A. Research side (the actual research ideas, tough to explain in 300 words, can be discussed in brainstorming session) B. The product it will enable. (UI based concept demo, with product/market fit that will it will enable)
