AI Analysis

●MidEye CandyShip It

Polished Arc-inspired email mockup, but it's a PoC with fake data.

Strengths

•Arc-style sidebar navigation adapted thoughtfully for email workflows.
•Clean visual design with attention to animation details.

Weaknesses

•Frontend PoC only — no actual email backend or AI agents working.
•Email client space is crowded; Superhuman, Spark, Hey already exist.

Post Description

Email is one of those tools we check daily but its underlying experience didn’t evolve much. I use Gmail, as probably most of you reading this.

The Arc browser brought joy and taste to browsing the web. Cursor created a new UX with agents ready to work for you in a handy right panel.

I use these three tools every day. Since Arc was acquired by Atlassian, I’ve been wondering: what if I built a new interface that applied Arc’s UX to email rather than browser tabs, while making AI agents easily available to help manage emails, events, and files?

I built a frontend PoC to showcase the idea.

Try it: https://demo.define.app

I’m not sure about it though... Is it worth continuing to explore this idea?
