I built Rumor.io, beautifully visualized social media sentiment data for investors. Have you ever wondered what other investors are talking about? This is it, visualized.
Rumor.io tracks over 14,000 stocks, cryptocurrencies, and ETFs across 1.5 billion social media posts with a 15+ year history. It merges the Firm-Foundation and Castle-in-the-Air theories to help investors choose assets with both solid fundamentals and crowd attention. The tool can be connected to an AI assistant for natural language queries.

score
score 5 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
