Vantafin is an investing and market research platform designed to make institutional-grade data and AI tools accessible to individual investors and developers. Its web app brings market information, company research, charts, screening, alerts, and AI chat together in one place, with free access to get started and paid plans for additional capabilities.
Users can explore more than 20,000 stocks, ETFs, and funds, review company financials and SEC filings dating back to 1994, follow market news, and track earnings events. The platform offers live quotes for over 9,000 tickers on Pro, along with a screener covering more than 80 fundamental and technical metrics. Price, filing, and news alerts can be delivered by email or Telegram. Brokerage syncing displays holdings, cost basis, and daily profit and loss.
Vantafin’s AI Chat provides answers grounded in financial data, filings, and transcripts, with citations to sources. Developers can access the same data through REST and WebSocket APIs or an MCP server compatible with tools such as Claude and Cursor.
