Design feedback

What it does

AI made it insanely easy to build apps. But many still feel like prototypes. Great ideas get ignored because the UX just feels off. Design Feedback helps you get clear, actionable UI/UX feedback from real designers—focused on improving conversion, not just looks. For developers: understand what’s wrong and fix it fast (or use it with AI tools). For designers: work on real products and build meaningful portfolios. No vague comments. Just feedback you can ship.

Drop your design. Get honest reviews from real designers. Apply the fixes with AI in minutes. Free to start.

  Hi HN, As PMs (Google, Gopuff, Shiji), my cofounder and I ran hundreds of user tests over the years. And every time it felt broken: It could take 2–5 days just to get enough usable results We spent hours watching recordings to extract a handful of insights “Professional testers” rushed through tasks for pay, creating biased feedback Platforms often started at €10k+ per year, with hidden fees on top The result: slow iteration cycles, unreliable feedback, and user testing that often felt like a tax rather than a tool. We started asking: what if AI could help? Could synthetic users replicate…

  As a founder, I've always had the hardest time building landing pages. You either buy a template and spend hours editing, or scream at Cursor to "make it beautiful". It's exhausting and waste of our time as founders. We simply need AI to generate beautiful landing pages that we can ship. I'd been working on this problem statement for a while and was able to get great results when I provided AI with a detailed design system to follow. So I ended up building a collection where I've curated 100s of design systems for AI tools to use. Now, after launch of Nano-Banana, I updated our flow to first…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
