Are AI‑generated UI designs good enough for production apps?

I continue building UI pages for my email marketing platform using AI, and I wondered if AI‑generated UI designs are good enough for production apps? They seem to work great on mobile devices and desktop screens. They load fast. They behave normally. I’m personally perfectly fine and happy to use them in production, but what is your opinion? Am I missing something? Should I be worried about...

How I create UI quickly using Stitch + Lovable

There is a very quick way to create UI for a mobile application or a website. I used this approach to create the UI for one of my side projects. To create the design, I used Google Stitch (https://stitch.withgoogle.com/). Stitch allows you to design using prompts, then edit specific parts of the image by highlighting them and describing what to change. You can download the designs in HTML or...

AI can remove something important without telling you 😅

It’s the third week of working on my little side project, SimploMail.com, and to speed things up I’ve been doing a lot of “vibe coding.” It’s been fun, but a few things became obvious pretty quickly. I stopped using the “auto” model setting in the IDE. When it silently switches models, the quality drops fast. I can feel when the agent all of a sudden looses its intelligence 😅. So now I just...

Hello fellow creators 🙋🏻‍♂️

My name is Sergey and I am a software developer. I am here because I started building a service I wanted to build for a several years now - A pay-as-you-go email marketing platform. I could not find a service that does not charge if I am not sending any email campaigns. So I decided to create one. Building in public is very new to me and I have zero experience sharing about it. But I will try...
