Honest AI forecasts for crypto and stocks. KOSAK analyzes cryptocurrency (Bitcoin, Ethereum and more), Korean stocks and US stocks in one dashboard — with an AI outlook score for each. Built by a developer who works in AI and deep learning, and unlike most apps, KOSAK never inflates its accuracy: short-term hit rate is usually ~50% (a coin flip), and we show it honestly, including the misses.

🧠 Honest AI investment forecasts, built by an AI researcher

It's built by a developer who actually works in AI, machine learning and deep learning — and unlike most apps, KOSAK shows its hit rate honestly (usually ~50%, coin-flip level). No hype, just honest info to help you decide for yourself.

✅ Why KOSAK is different

3) One of the few apps with BOTH on-device deep learning and pooled server ML
4) Crypto, KR & US stocks in one app

⚠️ All scores/forecasts are reference only and do not guarantee profit. Short-term markets are near-random (~50%). KOSAK is an information app with no trading, wallet, or advisory functions. Your decisions and responsibility are your own.
