The Buffett Screen: Screen any stock through Warren Buffett's eyes

Hey Product Hunt! 👋 I'm Takarudana — solo builder, 15-year trader, and the person who spent way too many evenings manually running Warren Buffett's 10 criteria on stocks I was researching. The problem was always the same: Buffett's framework is brilliant, but applying it properly means checking ROE, net margins, debt-to-equity, free cash flow, P/E ratios, earnings growth, pricing power, competitive moat, management quality, and margin of safety — for every single stock. That's not analysis. That's homework. So I built The Buffett Screen. Enter any ticker. In seconds you get: → A BUY, WATCH, or NO BUY verdict → A Buffett conviction score out of 100 → A plain-English analysis written in Buffett's own voice → Your stock's moat type and competitive position It's completely free. No signup. No credit card. A few stocks worth running through it to see what I mean: KO, AAPL, BRK.B — Buffett's own holdings. Then try something speculative like a meme stock and watch the score crater. That contrast alone will show you exactly what the tool does. This is one piece of a bigger platform — Market Investigation — where I'm building the research stack for startup founders and serious investors. 70+ guides already live, five more AI tools alongside this one. Building in public, bootstrapped, and genuinely grateful for every upvote today. Ask me anything below — I'll be here all day. 🙏
