As answered by people managing QuantLink and WhaleWisdom.
QuantLink's answer
QuantLink brings data that usually sits behind institutional subscriptions into one free-to-start terminal: AI agents that read primary SEC filings, machine learning factor models, congressional trade tracking under the STOCK Act, 13F institutional holdings, and insider Form 4 activity. Most retail tools stop at price and charts. QuantLink adds the primary-source and modeling layers on top.
QuantLink's answer
Screeners like Finviz and Koyfin handle price and charts well but stop at the surface. QuantLink pairs a screener and machine learning factor models with primary-source depth: AI analysis grounded in actual 10-K, 10-Q, and 8-K filings, plus congressional, 13F, and insider data in one place.
QuantLink's answer
We built QuantLink so retail investors could get research tools on par with what professionals use, without the $20,000 Bloomberg Terminal price tag. The filings that matter most, 10-Ks, 10-Qs, and 8-Ks, hold the real business story, but most people never read them. Our AI agents do the reading, and we layered on the data most screeners skip: congressional trades, 13F holdings, and insider activity.
QuantLink's answer
Individual investors, retail traders, financial analysts, and finance students who want institutional-grade research without institutional pricing. Focused on US equities.
