  I accidentally built a startup idea validation tool2025 · validationly.com · ▲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/

  Every AI agrees with you. This writes your startup's obituary insteadSep 2026 · theyfell.com · ▲9

  A business, a website, a GitHub, a resume, a career, a side project. An AI reads the real thing and writes the brutal, funny obituary it earned. Free, and it takes about ten seconds. Then order the full autopsy: cause of death, time of death, and how to cheat it.

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
