I made this for people like myself who keep a list of ideas for apps / startups. I also made it for people who are curious to see what projects others have "in their drawer"... and who may want to have a say in which idea should see the light of day. https://ideas.dynamate.io/ The site allows creators to anonymously showcase their idea: Title. Description text. Maybe some mockups... I've tried to make it so that it's quick and easy to just dump an idea in there that's been sitting on some list of yours for months - and hopefully get some feedback on it. If someone else on…

Validate Before You Create - See If Your Idea Already Exists

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 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 started a newsletter sending out daily startup ideas. After a year, I transitioned to weekly ideas with more in-depth details. I recently posted all of them to the website and made them searchable. Check it out and let me know what you think. By providing more than just an idea, my hope is to help someone start their next business. https://www.startupsfromthebottom.com/

I built a tool (https://1mil.app/hn) to help me test my intuition about various weird business ideas that were on my mind. Initially, I wanted to create a database with 1 million business ideas (hence the name - "1 million opportunities"). But turned out to be a dumb idea already. So instead I built this tool that returns only 10 ideas. It's all based on your input, market + your background. The first release scored on demand only and it gave false confidence. So I rebuilt the the scoring around "winnability": can a solo founder with a specific background "win" against what…

So I've been obsessed with a weird question for the past 6 months, what happens to SEO when everyone starts asking ChatGPT for recommendations instead of Googling? The answer, apparently, is chaos. And maybe opportunity? I built FirstClick because I noticed something strange. My previous startup was getting zero traffic from AI assistants, but our competitor (objectively worse product, sorry not sorry) was getting mentioned by Claude and Perplexity constantly. It drove me crazy. So I reverse engineered why. Turns out there's a whole new game being played and most founders don't even know it…

I’ve been studying real-world SaaS ideas — some that took off, others that failed hard. I turned it into a small side project: StartUp or Flop? You get two real startup ideas. One became successful, the other didn’t. You guess which is which, then you get the actual answer plus a short explanation of what made it work (or not). It’s a lightweight way to learn from real startup outcomes, uncover the patterns behind success and failure, sharpen your product instinct — and maybe even confront some of your own startup biases along the way. It’s surprising, humbling, and kind of addictive. Would…
