I made a tool to help collect and validate startup ideas▲38
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!

I accidentally built a startup idea validation tool▲15
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/

A site to help you validate ideas in bulk▲93
Hi HN! I made a really quick web app to help people validate their ideas. The app is a simple landing page builder, but every page includes a really simple Yes/No "Are You Interested?" poll. Every vote is recorded and tracked, and if they click yes they are brought to a page where they can submit an email. This makes validating ideas super easy because you can post your link to different communities and get statistically significant results as well as build an email list. Given an hour, you could easily create 50 different landing pages and be able to validate your ideas in bulk. The…
