The full intelligence stack for prediction market data
News Signals
Articles clustered and matched to markets in real time. Each story is tagged New, Update, or Rehash based on how much genuinely new information it carries.
Cross-Platform Pricing
Same event on Polymarket vs Kalshi, unified. Embedding similarity + LLM validation finds matches with zero false positives.
Event Relationships
Automatic classification of how markets relate: partitions, term structures, hierarchies. See what your positions imply.
Portfolio P&L
Paste a wallet, see complete trade history, realized P&L chart, open positions, and resolved outcomes with win rate.
Semantic Search
Search markets by meaning, not keywords. "Will inflation drop?" finds rate cut markets, CPI contracts, and more.
