I invest only in stocks that meet my own criteria, which I built around a paper called "Buffett's Alpha" (Quality Minus Junk, Betting against Beta). If they meet the criteria I buy, once they don't I sell.

I wanted to define this only once and automate all the research and matching. So I started "Critivest" back in 2020 and launched it just now.

It let's you define your own investment strategy and notifies you whenever a stock on your watchlist matches or fails it. Would love feedback if you find it useful and usable.

It's free and there's a demo without registration.
