    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…

    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…

    http://www.upboat.us Demo: http://www.upboat.us/idea/upboat Screenshot of logged-in view: http://i.imgur.com/vUZXfZc.png Upboat is an idea validation platform, somewhere inbetween Kickstarter and LaunchRock. If the idea you pitch receives over 200* "upboat"s (consented would-be users) within one week, you get the whole emailing list of all those who upboat'd it. If not, you get nothing. This is helpful for those who have ideas for side-projects, but lack the strong-enough incentive to get to work and just hack something together. Should you put up…

    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/

    Inspired by the following post by photon_off... http://news.ycombinator.com/item?id=1683309 I made karmurl last night. It's a simple app where you submit a URL for feedback, then for every piece of feedback you give to someone else's, you get to read one piece of feedback for yours. http://karmurl.com

    this is an open-source project. the MVP to end all MVPs. made by me, a teenage developer angry at FAANG employees for creating a soulless, consumer-oriented world. The future is in creation, and the future is in teaching people to slam shit together with ChatGPT. Welcome to the start. :P
