Astera AI

Real-time intelligence for sports and markets. Free to use. Ask any question about any sporting event, any stock, any crypto, any election. Get real, accurate answers backed by live and historical data, not guesswork. The best pricing, the deepest analysis, and every market you care about, all in one place.

ASK SHARPE ANYTHING
Sharpe is an AI agent built for markets. It outperforms every frontier AI model on independent finance and sports benchmarks. And it is free. Sharpe does not just answer questions. It surfaces the most relevant questions for you, live, based on whatever event or market you are looking at. Open a sporting event and Sharpe already knows to ask about the spread, the total, and recent trends. Open a stock and it surfaces the earnings question, the competitive risk, the sector rotation. Purpose-built knowledge graphs, not generic web search.
Sports: "How often do the Clippers cover on the road?" / "Does this pitching matchup favor the over?"
Stocks: "How does AMZN's AWS growth compare to Azure and GCP?" / "What are NVDA's key risks after earnings?"
Elections: "Who controls the House? What do the prediction markets say?"
Crypto: "Is BTC breaking out or faking out?" / "How does ETH correlation with equities change in risk-off?"
Climate: "Will a Category 5 hurricane make US landfall before 2027?"
Culture: "Will a new streaming service win an Emmy before 2028?"
