Sumari extracts the catalyst behind every stock and crypto move and delivers it as one sentence with a source. Built for retail investors who'd rather know why in 10 seconds than scroll Yahoo, X, and 5 articles for 15 minutes. No predictions. No analyst-speak. Sourced.
Hey Product Hunt 👋
I'm Francis, solo dev behind Sumari, and I’m thrilled to share our public launch with you.
If you pick your own stocks or hold crypto — this one's for you.
You've lived this moment a hundred times: your phone buzzes, NVDA is down 4%, and you do the same dance every time. Open Yahoo Finance. Skim a headline. Switch to X, scroll past five hot takes. Open Google News, click an article — the lede is "analysts are worried." Twelve minutes in, you still don't actually know what happened.
The catalyst is always one sentence. It's always buried.
Sumari extracts that sentence. Source attached, direction tagged, in under 10 seconds. And — this is the part that took months to get right — if the article doesn't actually say what happened, the output is blank. Not fabricated. A blank catalyst is always better than a wrong one.
Here's what's inside ⚙️
📈 One-sentence catalyst on every stock and crypto move — no "could push higher," no "investors are worried"
🔔 Push alerts when something you track moves abnormally — statistical anomaly detection, not noise
📅 Earnings & macro calendar with verdicts pulled from primary sources (SEC, Fed, ECB — not commercial wires)
🎯 Personal watchlist + sector sentiment so the noise filters itself before it reaches you
🧱 Built solo over 12 months by a retail investor tired of the 15-minute scramble
Time To Clarity: 15 minutes → 10 seconds.
If you invest in individual stocks or crypto, you can't miss this — Sumari is built for exactly the person who checks their portfolio daily and wants to actually understand the moves, not just stare at red and green.
We're excited to hear what you think — what works, what's missing, what would make Sumari the first thing you open when your portfolio moves. Help us build the place every retail investor turns to before the headlines spin them up 🧭
As a thank-you for all your love and support, I will give you Pro tier FREE forever 🙌 for the first 100 Product Hunt community members who sign up during launch week 🤑💸
