About this app

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

KOSAK analyzes crypto, Korean stocks and US stocks in one place. 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.

📊 AI prediction & analysis
• AI outlook score — buy/sell/hold from moving averages, RSI, MACD, volume
• 🤖 Deep-learning signal — a neural net trains on each asset to predict the next move (honest walk-forward hit rate)
• 🌐 Server ML — an extra signal pooled across many assets (crypto, KR, US)
• 🔬 Self-verified backtesting — hit rate measured on past data, shown as-is
• 📈 Next-bar & long-term forecasts + similar-pattern analysis

📉 Charts & tools
• Candlestick chart + AI forecast line in one view
• Drawing tools: trendlines, horizontals, Fibonacci, volume profile (full history)
• Minute / hour / day / week / month timeframes

🔔 Alerts (even when the app is closed)
• New-listing alerts — Upbit, Binance, US stock IPOs (toggle each source)
• Price target alerts — loud sound & vibration
• Telegram alerts — watchlist digest

📒 Tracking & market info
• AI trading journal — buy/sell & averaging records → auto avg price/P&L, mistake coaching
• Kimchi premium (Upbit vs Binance)
• Fear & Greed index + market summary (total market cap, BTC dominance)
• US CPI/PPI calendar + news-based impact interpretation
• Liquidation map (Coinglass) quick link

🌏 More
• 📚 Learning center — crypto & stock basics to charts, indicators, strategy
• Crypto (Upbit, Binance $) + KR stocks (KRX) + US stocks, unified
• 14 languages · dark theme · password lock
• Works without login (cross-device sync optional)

✅ Why KOSAK is different
1) Built by an AI researcher
2) Shows its hit rate openly, never hides it
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.
