Quantral

Quantral is an investment ideas app built on alternative data. It reads what the finance accounts and communities we track are saying on X, Reddit, Substack and YouTube, alongside Congress trades and insider buys, and scores every stock 0-100. Every voice gets a track record: Quantral grades every call it tracks, losers included, so you can see which ideas are gaining traction and whether the people behind them have been right before. Why I built it: I'm a product designer who started investing on the side, followed the most confident voices in my feeds, and lost money doing it. Nobody was keeping score, so I built something that does. Available on iOS, Android and the web, plus a read-only MCP server for Claude and ChatGPT. Not financial advice.
