    Hey HN, I’m Kyrylo. I recently created a small tool that lets you gather, refine, and validate SaaS/startup ideas using AI. I used to jot down my product ideas in a note apps, but it wasn’t very practical for collecting feedback or refining them. So, I built this tool to make the process easier. Here’s how it works: 1. Enter a brief description of your idea. 2. The app uses AI to generate project details. 3. Share your idea via a link that includes a feedback form. It’s pretty straightforward, and I’d love to hear your thoughts or any suggestions!

    A passion project I started recently. Please submit your own (or any) website you suspect might score high as "AI-slop" and we'll publish a roast soon. Note that my goal is two-fold: I'll use (most) submitted websites in some research I'm going to be publishing later. Thanks!

    I was working on validating some of my own project ideas. While trying to find how to validate my idea, I realized the process itself could be turned into a tool. A few late nights later, I had something that takes any startup idea, fetches discussions, summarizes sentiment, and gives a quick “validation score.” It’s very rough, but it works, and it’s already making me rethink a few of my own ideas. It's still a work in progress. I don't actually know what I'm doing, but I know it's worth it. Honest feedback welcomed! Live demo here: https://validationly.com/

    Hey HN, I’m Ishan, a 23-year-old, and this is my first time launching something here. I built a simple (free) tool that uses AI to roast websites. Just enter your URL, and it gives a fun, sometimes brutal, review. It’s mostly for laughs, but it also points out things you can improve on your website. I’d love for you to try it out and give me feedback!
